Evaluating the use of ram and suction during prey capture by cichlid fishes. (1/403)

We characterized prey-capture strategies in seven species of cichlid fishes representing diverse trophic habits and anticipated feeding abilities. The species examined were Petenia splendida, Cichla ocellaris, Cichlasoma minckleyi, Astronotus ocellatus, Crenicichla geayi, Heros severus (formerly Cichlasoma severum) and Cyprichromis leptosoma. Three individuals per species were filmed with video at 500 Hz as they captured live adult Artemia sp. and Poecilia reticulata. For each feeding sequence, we measured the contribution of predator movement towards the prey (i.e. ram) and the movement of prey towards the predator due to suction. The use of ram differed significantly among prey types and predator species, varying as much as sixfold across predator species. High values of ram resulted in high attack velocities. Jaw protrusion contributed as much as 50% to overall ram values in some species, verifying its role in enhancing attack velocity. Suction distance did not vary significantly among species. Diversity in prey-capture behavior was therefore found to reflect differences among species in the strategy used to approach prey. Limited variation in the distance from which prey were sucked into the mouth is interpreted as the result of an expected exponential decline in water velocity with distance from the mouth of the suction-feeding predator. We propose that this relationship represents a major constraint on the distance over which suction feeding is effective for all aquatic-feeding predators.  (+info)

Spironucleus vortens, a possible cause of hole-in-the-head disease in cichlids. (2/403)

Hole-in-the-head disease is recorded in 11 discus Symphysodon discus Heckel, 1840 and 1 angelfish Pterophyllum scalare Lichtenstein, 1823 obtained from local aquarists within the Southwest of the UK. Spironucleus vortens Poynton et al. 1995, was isolated from the kidney, liver, spleen and head lesions of discus showing severe signs of the disease and from the intestines of all fish. The hexamitid was also recorded from the head lesions of the angelfish. The identity of these flagellates was confirmed as S. vortens on the basis of topographical features seen with the aid of SEM. A modified in vitro culture method was successfully developed for the detection, isolation and long-term maintenance of S. vortens. The flagellate was sub-cultured at 3 to 5 d intervals, new media being supplemented with fresh liver from Oreochromis niloticus (Linnaeus, 1757) free from infection. The results are discussed in relation to S. vortens as the causative agent for hole-in-the-head disease following systemic infection via the digestive tract.  (+info)

Phylogenetic relationships and ancient incomplete lineage sorting among cichlid fishes in Lake Tanganyika as revealed by analysis of the insertion of retroposons. (3/403)

Lake Tanganyika harbors numerous endemic species of extremely diverse cichlid fish that have been classified into 12 major taxonomic groups known as tribes. Analysis of short interspersed element (SINE) insertion data has been acknowledged to be a powerful tool for the elucidation of phylogenetic relationships, and we applied this method in an attempt to clarify such relationships among these cichlids. We studied insertion patterns of 38 SINEs in total, 24 of which supported the monophyly of three clades. The other 14 loci revealed extensive incongruence in terms of the patterns of SINE insertions. These incongruencies most likely stem from a period of adaptive radiation. One possible explanation for this phenomenon is the extensive incomplete lineage sorting of alleles for the presence or absence of a SINE during successive speciation events which took place about 5-10 MYA. The present study is the first to report the successful application of the SINE method in demonstrating the existence of such possible "ancient" incomplete lineage sorting. We discuss the possibility that it might potentially be very difficult to resolve the species phylogeny of a group that radiated explosively, even by resolving the genealogies of more than 10 nuclear loci, as a consequence of incomplete lineage sorting during speciation.  (+info)

History and timing of human impact on Lake Victoria, East Africa. (4/403)

Lake Victoria, the largest tropical lake in the world, suffers from severe eutrophication and the probable extinction of up to half of its 500+ species of endemic cichlid fishes. The continuing degradation of Lake Victoria's ecological functions has serious long-term consequences for the ecosystem services it provides, and may threaten social welfare in the countries bordering its shores. Evaluation of recent ecological changes in the context of aquatic food-web alterations, catchment disturbance and natural ecosystem variability has been hampered by the scarcity of historical monitoring data. Here, we present high-resolution palaeolimnological data, which show that increases in phytoplankton production developed from the 1930s onwards, which parallels human-population growth and agricultural activity in the Lake Victoria drainage basin. Dominance of bloom-forming cyanobacteria since the late 1980s coincided with a relative decline in diatom growth, which can be attributed to the seasonal depletion of dissolved silica resulting from 50 years of enhanced diatom growth and burial. Eutrophication-induced loss of deep-water oxygen started in the early 1960s, and may have contributed to the 1980s collapse of indigenous fish stocks by eliminating suitable habitat for certain deep-water cichlids. Conservation of Lake Victoria as a functioning ecosystem is contingent upon large-scale implementation of improved land-use practices.  (+info)

Iridovirus infections in farm-reared tropical ornamental fish. (5/403)

A systemic viral infection in both gourami Trichogaster spp. and swordtail Xiphophorus hellerii and an outbreak of lymphocystis in scalare Pterophyllum scalarae and gourami are reported to have occurred in fish reared in ornamental fish farms in Israel. The systemic infection developed in endothelial cells that became hypertrophic and their contents were modified. The presence of such cells in light-microscopically examined stained smears and sections provides an initial indication for this systemic viral infection. Infection in gourami caused hemorrhagic dropsy. Transmission electron microscopic (TEM) images of iridovirus-like particles recovered from gouramies showed them to be 138 to 201 nm from vertex to vertex (v-v); those from swordtails were 170 to 188 nm v-v. TEM images of lymphocystis virions from scalare were 312 to 342 nm v-v and from gourami 292 to 341 nm v-v. Lymphocystis cells from the gourami were joined by a solid hyaline plate, which was lacking in the infection in scalare where the intercellular spaces between the lymphocystis cells consisted of loose connective tissue.  (+info)

Patterns in fish radiation are compatible with Pleistocene desiccation of Lake Victoria and 14,600 year history for its cichlid species flock. (6/403)

Geophysical data are currently being interpreted as evidence for a late Pleistocene desiccation of Lake Victoria and its refilling 14,600 years ago. This implies that between 500 and 1000 endemic cichlid fish species must have evolved in 14,600 years, the fastest large-scale species radiation known. A recent review concludes that biological evidence clearly rejects the postulated Pleistocene desiccation of the lake: a 14,600 year history would imply exceptionally high speciation rates across a range of unrelated fish taxa. To test this suggestion, I calculated speciation rates for all 41 phylogenetic lineages of fish in the lake. Except for one cichlid lineage, accepting a 14 600 year history does not require any speciation rates that fall outside the range observed in fishes in other young lakes around the world. The exceptional taxon is a lineage of haplochromine cichlids that is also known for its rapid speciation elsewhere. Moreover, since it is unknown how many founding species it has, it is not certain that its speciation rates are really outside the range observed in fishes in other young lakes. Fish speciation rates are generally faster in younger than in older lakes, and those in Lake Victoria, by far the largest of the young lakes of the world, are no exception. From the speciation rates and from biogeographical observations that Lake Victoria endemics, which lack close relatives within the lake basin, have such relatives in adjacent drainage systems that may have had Holocene connections to Lake Victoria, I conclude that the composition of the fish assemblage does not provide biological evidence against Pleistocene desiccation. It supports a hypothesis of recent colonization from outside the lake basin rather than survival of a diverse assemblage within the basin.  (+info)

What, if anything, is a Tilapia?-mitochondrial ND2 phylogeny of tilapiines and the evolution of parental care systems in the African cichlid fishes. (7/403)

We estimated a novel phylogeny of tilapiine cichlid fish (an assemblage endemic to Africa and the Near East) within the African cichlid fishes on the basis of complete mitochondrial NADH dehydrogenase subunit 2 (ND2) gene sequences. The ND2 (1,047 bp) gene was sequenced in 39 tilapiine cichlids (38 species and 1 subspecies) and in an additional 14 nontilapiine cichlid species in order to evaluate the traditional morphologically based hypothesis of the respective monophyly of the tilapiine and haplochromine cichlid fish assemblages. The analyses included many additional cichlid lineages, not only the so-called tilapiines, but also lineages from Lake Tanganyika, east Africa, the Neotropics and an out-group from Madagascar with a wide range of parental care and mating systems. Our results suggest, in contrast to the historical morphology-based hypotheses from Regan (1920, 1922 ), Trewavas (1983), and Stiassny (1991), that the tilapiines do not form a monophyletic group because there is strong evidence that the genus Tilapia is not monophyletic but divided into at least five distinct groups. In contrast to this finding, an allozyme analysis of Pouyaud and Agnese (1995), largely based on the same samples as used here, found a clustering of the Tilapia species into only two groups. This discrepancy is likely caused by the difference in resolution power of the two marker systems used. Our data suggest that only type species Tilapia sparrmanii Smith (1840) should retain the genus name TILAPIA: One particular group of tilapiines (composed of genera Sarotherodon, Oreochromis, Iranocichla, and Tristramella) is more closely related to an evolutionarily highly successful lineage, the haplochromine cichlids that compose the adaptive radiations of cichlid species flocks of east Africa. It appears that the highly adaptable biology of tilapiines is the ancestral state for all African cichlids and that the more stenotypic lifestyle of the haplochromine cichlids is derived from this condition. We reconstructed the evolution of the highly variable parental care systems on the basis of the most inclusive composite phylogeny to date of the African, Neotropical, and Madagascan cichlids with special emphasis on a group of tilapiines comprising the substrate-spawning genus Tilapia, and the mouthbrooding genera Sarotherodon and OREOCHROMIS: We demonstrate several independent origins of derived mouthbrooding behaviors in the family Cichlidae.  (+info)

Mosaic structure and retropositional dynamics during evolution of subfamilies of short interspersed elements in African cichlids. (8/403)

The African cichlid (AFC) family of short interspersed elements (SINEs) is found in the genomes of cichlid fish. The alignment of the sequences of 70 members of this family, isolated from such fish in Africa, revealed the presence of correlated changes in specific nucleotides (diagnostic nucleotides) that allowed us to categorize the various members into six subfamilies, which were designated Af1 through Af6. Dividing the SINE consensus sequence into a 5'-head and 3'-tail region, these subfamilies were defined by various combinations of four types of head region (A-D) and three types of tail region [X, Y, and (YX)], with each region of each type including unique diagnostic nucleotides. The observed structures of the subfamilies Af1 through Af6 were AX, AY, CY, A(YX), BY, and DX, respectively. The formation of such structures might have involved the shuffling of head or tail regions among preexisting and existing (or both) subfamilies of the AFC family (and, probably, even another SINE family or a pseudogene for a tRNA in the case of the Af6 subfamily) by recombination at the so-called core region during the course of evolution. By plotting the timing of the retroposition of individual members of each subfamily on a phylogenetic tree of AFCs, we found that the Af3 and Af6 subfamilies became active only recently in the evolutionary history of these fish. The integrity of the 3'-tails of SINEs, which are, apparently, recognized by reverse transcriptase, has been reported to be indispensable for retention of retropositional activity. Therefore, we postulate that recombination might have been involved in the apparent recent activation of the retroposition of the Af3 and Af6 subfamilies via introduction of active tails (types Y and X, respectively) into potential ancestral sequences that might have had inactive tails. If this hypothesis is correct, shuffling of tail regions among subfamilies by recombination at the core region might have played a role in the recycling of dead copies of AFC SINEs.  (+info)

Despite teleosts being the largest and most diverse group of vertebrates, fish models currently used to study photoperiodic effects on fish physiology have been limited to a few species, most of which are temperate seasonal breeders. The overall aim of this work was to expand our knowledge on circadian biology and environmental physiological effects in Nile tilapia (Oreochromis niloticus niloticus), a continuous breeding species of tropical-subtropical origin. The circadian light axis of Nile tilapia is described with regards to melatonin production. Circadian melatonin profiles of fish under 12L:12D photoperiods were observed to be low at day and high at night, suggesting melatonin to be an entraining signal as observed in all other vertebrates. When constant light (LL) was used, such day and night fluctuations where abolished. However when fish where exposed to constant darkness (DD) a strong robust endogenous melatonin rhythm was found, suggesting the presence of circadian oscillators in this ...

Abstract Traditionally, fish oil (FO) has been used extensively in aquafeeds. The stagnation in global fish oil production coupled with an increased demand for its use in aquaculture feeds, especially salmonid feeds, has greatly inflated fish oil prices. Therefore, in order to sustain the rapid growth of the tilapia industry, the dependence on these commodities in feeds should be reduced through use of cheaper and more sustainable sources of dietary lipids, such as palm oil. This study therefore investigated several, previously poorly understood, effects of palm oil on reproductive performance of the commercial tilapia species, Oreochromis niloticus; which currently ranks as second most popular species in world aquaculture. In the present study broodstock were fed on experimental diets at full and half ration regimes throughout their entire life cycle from exogenous feeding. Studies were conducted in standardised and controlled hatchery conditions, thereby reducing the potential influence of ...
Pseudomonas aeruginosa (P. aeruginosa) produces a suite of virulence factors that are coordinated by Quorum Sensing (QS) contributing to its disease-causing ability in aquaculture. The present study is first of its kind to obtain information regarding the presence and distribution of five QS genes, three virulence genes viz: lasI, lasR, rhlI, rhlR, rhlAB, toxA, aprA and plcH and seven of the Extended-spectrum βlactamases (blaVEB, blaPER, blaTEM,, blaSHV, blaCTX-M1, blaCTX-M2 and blaCTX-M3) of Pseudomonas species isolated from fish meat by direct PCR. Bacterial identification was based mainly on conventional biochemical techniques using the Vitek 2, automated system. Phenotypic sensitivity of antibiotics was established by the agar disc diffusion technique through 16 various antimicrobial drugs. Quantification of their in vitro production of numerous virulence genes outside the cell that are QS dependent namely, pyocyanin, elastase, alkaline protease, biofilm and cytotoxicity of Vero cell was as
Sex chromosomes change more frequently in fish than in mammals or birds. However, certain chromosomes or genes are repeatedly used as sex determinants in different members of the teleostean lineage. East African cichlids are an enigmatic model system in evolutionary biology representing some of the most diverse extant vertebrate adaptive radiations. How sex is determined and if different sex-determining mechanisms contribute to speciation is unknown for almost all of the over 1,500 cichlid species of the Great Lakes. Here, we investigated the genetic basis of sex determination in a cichlid from Lake Tanganyika, Astatotilapia burtoni, a member of the most species-rich cichlid lineage, the haplochromines. We used RAD-sequencing of crosses for two populations of A. burtoni, a lab strain and fish caught at the south of Lake Tanganyika. Using association mapping and comparative genomics, we confirmed male heterogamety in A. burtoni and identified different sex chromosomes (LG5 and LG18) in the two
article{9cc27631-773b-4625-add5-aeb353c7d0cb, abstract = {,p,Parasite diversity and abundance (parasite load) vary greatly among host species. However, the influence of host traits on variation in parasitism remains poorly understood. Comparative studies of parasite load have largely examined measures of parasite species richness and are predominantly based on records obtained from published data. Consequently, little is known about the relationships between host traits and other aspects of parasite load, such as parasite abundance, prevalence and aggregation. Meanwhile, understanding of parasite species richness may be clouded by limitations associated with data collation from multiple independent sources. We conducted a field study of Lake Tanganyika cichlid fishes and their helminth parasites. Using a Bayesian phylogenetic comparative framework, we tested evolutionary associations between five key host traits (body size, gut length, diet breadth, habitat complexity and number of sympatric ...
Cichlids are a diverse group of fish from the family Cichlidae. There are an estimated 1300 to 3000 species of cichlids. They come in a variety of shapes and sizes, ranging from 2.5 cm to 1 meter in length and can live for 4-10 years. Cichlids originated in Africa but can be found in South America as well; most notably, they are found in Lake Malawi, Lake Tanganyika and Lake Victoria. In Lake Malawi alone, there are an estimated 1,000 different types of cichlid species (Evolutionary Biology). They prefer fresh to brackish water and usually live near the waters surface. Many cichlids are herbivores that feed on algae, but some are predatory and consume other small fish or insect larvaes.. Why study Cichlids? Cichlids are great model organisms to study because they represent rapid and convergent evolutionary radiation in vertebrates. Also, there is a large variety of cichlids which makes it easier for scientists to study multiple phenotypic traits.. Cichlid Reproduction. Cichlids demonstrate four ...
The hundreds of endemic species of cichlid fishes in the East African Great Lakes Tanganyika, Malawi, and Victoria are a prime model system in evolutionary biology. With five genomes currently being sequenced, eastern African cichlids also represent a forthcoming genomic model for evolutionary studies of genotype-to-phenotype processes in adaptive radiations. Here we report the functional annotation and comparative analyses of transcriptome data sets for two eastern African cichlid species, Astatotilapia burtoni and Ophthalmotilapia ventralis, representatives of the modern haplochromines and ectodines, respectively. Nearly 647,000 expressed sequence tags were assembled in more than 46,000 contigs for each species using the 454 sequencing technology, largely expanding the current sequence data set publicly available for these cichlids. Total predicted coverage of their proteome diversity is approximately 50% for both species. Comparative qualitative and quantitative analyses show very similar ...

The jewel cichlid (which is a pearl color with blue dots) has been acting strange lately. She does not swim around only stays at the top of the tank. Her fins are all down and she curves her tailfin. She eats a little but not like she use to. She does not swim around although she has always kept to herself but now she is not acting normal. I have isolated her in a tank but I am at a loss as to what to do for her. Any advice would be appreciated. Thanks! Leslie , Clamped fins are a sign of a disease. Treat with Rid-Ich and salt for now.

Heritability estimates were determined for six phenotypes in Oreochromis niloticus for 180, 210 and 300 days old: body weight (BW), total length (TL), standard length (SL), body height (BH), caudal tail height (CTH) and head length (HL). Heritability estimates were calculated by half-sib analysis from an experiment that contained 3 paternal half-sib families and 11 full-sib families. Heritabilities ranged from 0.00-0.88. These results suggest that because heritabilities of BW, TL, SL, BH, CTH and HL for sires in Oreochromis niloticus for 180 and 210 days old are low, family selection or progeny testing can proposed for selection. But, therefore heritabilities of all traits both male and female for 300 days old are high, selection will propose for are mass selection.. ...
The ram cichlid, Mikrogeophagus ramirezi, is a species of freshwater fish endemic to the Orinoco River basin, in the savannahs of Venezuela and Colombia in South America. The species has been examined in studies on fish behaviour and is a popular aquarium fish, traded under a variety of common names, including ram, blue ram, German blue ram, Asian ram, butterfly cichlid, Ramirezs dwarf cichlid, dwarf butterfly cichlid and Ramirezi. The species is a member of the family Cichlidae and subfamily Geophaginae. Wild ram cichlids are often more colorful than the tank-bred fish, which suffer from poor breeding and also being injected with hormones for more color, although this makes as many as one in four males infertile.[citation needed] Male specimens of the ram usually have the first few rays of the dorsal fin extended, but breeding has made some females also show this. When close to spawning, female rams have a pink or red blush on the abdomen. Females also have a blue sheen over the spot just ...

Many shell-dwelling species are adaptations of these cave spawners and include Neolamprologus ocellatus. Their caves are made up of the empty, calcified shells of Neothauma snails which are preserved by the hard alkaline water. Shell dwellers can be kept in small tanks and make fascinating residents.. Mouthbrooders. These are also very popular with hobbyists, with the rock dwelling, algae grazing Tropheus, the large sedate, predatory Frontosa and the slender, open water Sardine cichlids making up the bulk of all such fish sold. The three are very different in their requirements, despite inhabiting the same lake, so should not be kept together in the same tank.. Tropheus look and behave like Pseudotropheus from Lake Malawi. Their diet is poor, consisting of short algae strands growing from rocks and the odd invertebrate found within the algae. This growth is commonly referred to as aufwuch. Tropheus are aggressive and territorial in the aquarium, as in nature they fight to protect their algae and ...
Population boundaries are largely determined by local environment, the strength of barriers to migration, and the organisms inherent dispersal abilities. The interaction among these and genetic factors determines the potential for evolutionary divergence, and is at the heart of our understanding of ecological adaptation and ongoing speciation processes. When individuals can easily cross barriers between suitable habitat patches, gene flow acts to homogenize most neutral genetic diversity and may swamp the effects of any local phenotypic selection whereas low levels of migration may facilitate ecological divergence, even when selection is modest. Evolutionary divergence through fine-scale geographic isolation is believed to be one of the main mechanisms promoting speciation in the cichlid radiations of the African Great Lakes [1-3]. Many lake species are extreme local endemics, with distributions limited to small patches of ecologically distinct habitat. Many narrowly endemic cichlid species are ...
Background Cichlid fishes have radiated into hundreds of species in the Great Lakes of Africa. Brightly colored males display on leks and vie to be chosen by females as mates. Strong discrimination by females causes differential male mating success, rapid evolution of male color patterns and, possibly, speciation. In addition to differences in color pattern, Lake Malawi cichlids also show some of the largest known shifts in visual sensitivity among closely related species. These shifts result from modulated expression of seven cone opsin genes. However, the mechanisms for this modulated expression are unknown. Results In this work, we ask whether these differences might result from changes in developmental patterning of cone opsin genes. To test this, we compared the developmental pattern of cone opsin gene expression of the Nile tilapia, Oreochromis niloticus, with that of several cichlid species from Lake Malawi. In tilapia, quantitative polymerase chain reaction showed that opsin gene ...

The firemouth cichlid (Thorichthys meeki) is a species of cichlid fish native to Central America. They occur in rivers of the Yucatán Peninsula, Mexico, south through Belize and into northern Guatemala. Their natural habitat is typically shallow, slow-moving, often turbid, water with a pH of 6.5 - 8.0. It has also been reported to live in underground cave systems. As fish with a tropical distribution, firemouth cichlids live in warm water with a temperature range of 23-30 °C (75-86 °F). The common name, firemouth, is derived from the bright orange-red colouration on the underside of the jaw. Males in particular flare out their gills, exposing their red throats, in a threat display designed to ward off male rivals from their territory. Like most cichlids, brood care is highly developed; this species is an egg-layer. Firemouth cichlids form monogamous pairs and spawn on flattened surfaces of rocks, leaves or submerged wood. Breeding males are primarily responsible for territorial defense, while ...

In this study, we wanted to take the first step in understanding vision in cichlids and to know whether they have true color vision. Further studies are needed to dissect the cichlid visual system as well as its adaptations and limitations but, given our visual modeling and behavioral results, we can infer the physiological characteristics of the cichlid retina. Initially, based on previous fish-vision studies applying the RNL model, we assumed a Weber fraction of 0.05 (Champ et al., 2016; Cheney et al., 2009; Dalton et al., 2016; Wilkins et al., 2016) for the LWS channel. However, in order to better predict cichlid performance, we adjusted this to a higher Weber fraction of 0.1. We did this because, even though we are not evaluating color discrimination thresholds, increasing the Weber fraction, and hence lowering chromatic distance, would partially explain the mistakes fish made (Figs 2 and 3). In general, a Weber fraction of 0.05 is accepted for most animals (Vorobyev and Osorio, 1998) but it ...
Although it is widely assumed that the evolution of jaw kinesis in the ray-finned fishes was an innovation to enhance suction feeding performance, the lack of phylogenetic replication of this event across fishes has hindered direct tests of this hypothesis. Our results reveal that within the East African cichlid radiations, multiple transitions between biting and suction feeding have occurred, and that these functional transitions are accompanied by evolutionary reduction of jaw kinesis over short evolutionary timescales of 4 Myr or less (figure 3). These rapid and repeated shifts are consistent with the hypothesis that high jaw kinesis is selectively maintained in suction feeding fishes and provides evidence supporting upper jaw protrusion as a major evolutionary innovation for ray-finned fishes.. Our power to detect associations between jaw kinesis and transitions in feeding mode is directly connected to the sheer number of dietary transitions that have occurred in these cichlid radiations, ...
Among multigene families, ribosomal RNA (rRNA) genes are the most frequently studied and have been explored as cytogenetic markers to study the evolutionary history of karyotypes among animals and plants. In this report, we applied cytogenetic and genomic methods to investigate the organization of rRNA genes among cichlid fishes. Cichlids are a group of fishes that are of increasing scientific interest due to their rapid and convergent adaptive radiation, which has led to extensive ecological diversity. The present paper reports the cytogenetic mapping of the 5S rRNA genes from 18 South American, 22 African and one Asian species and the 18S rRNA genes from 3 African species. The data obtained were comparatively analyzed with previously published information related to the mapping of rRNA genes in cichlids. The number of 5S rRNA clusters per diploid genome ranged from 2 to 15, with the most common pattern being the presence of 2 chromosomes bearing a 5S rDNA cluster. Regarding 18S rDNA mapping, the
The Yellowfin Borleyi Cichlid, also known as Haplochromis barlowi, originates from the Southern part of Lake Malawi, Africa. The males have a blue body with striking yellow fins, and are one of the larger Copadichromis Cichlids reaching a maximum size of 7. When mature, the females remain brown to silver in color, and will be slightly smaller than the males. A large aquarium with plenty of caves and hiding places is ideal for the Yellowfin Borleyi Cichlid. Caves can be formed from limestone or any other type of inert rock, as well as African Driftwood. An aragonite-based substrate is recommended in order to maintain the necessary high pH and alkalinity. They do not like bright lighting, and the aragonite should ideally be either mixed with or covered by darker gravel to reduce the amount of glare in the aquarium. The Yellowfin Borleyi Cichlid requires a substrate deep enough to burrow in during breeding time. For best results in spawning, the males should be kept with at least three females. ...
Swim-up fry (average weight, 14 mg) were obtained from Oreochromis niloticus (Chitralada strain) held in concrete tanks. In experiment 1 (1985), fry were fed diets treated with 17 alpha-methyltestosterone (MT) or progesterone at 60 mg/kg for 40 days. Control fish were fed untreated diet. Fingerlings (average weight, 2.86 g) were subsequently stocked at 1/square m. in earthen ponds receiving septic tank slurry at 150 kg COD/ha/day and fine rice bran as supplementary feed for about 5 months. In experiment 2 (1986), similar procedures were followed but the fry were fed MT at 40 mg/kg for 40 days and pond stocking rates of 1,3,5 and 7 fingerlings/sq. m were compared. Individual size, sex and stage of maturity were determined. In experiment 1, the average individual size was greatest in the MT-treated group (263 g), compared with the untreated (232 g) and progesterone-treated fish (189 g). The final size of fish in experiment 2 decreased significantly (P0.05) with density, from an average of 249 g at ...

And flourish it did in the Rift Valley lakes. If you were to visit these lakes, snorkel or scuba in their waters, you would most likely notice a wide variety of fish. You would not be wrong in this assessment; however, you might be surprised to find that most of these types of fish are belonging to a group called the cichlids (SICK-lids), and that all 1,650 plus species of these cichlids descended from a common ancestor. While the dates of when the common ancestor of the various cichlids came to be trapped in their respective lakes, it has been estimated that the cichlids of Lake Malawi all evolved from a common ancestor trapped 700,000 years ago, and those of Lake Victoria around 12,000 years ago. Trapped in these growing lakes while they were being formed, this small group of fish quickly came to dominate their new home, exploding in biodiversity to adapt to the wide variety of niches left open to them ...
in the mid to late 1980s. Its parentage has been highly disputed, but the most commonly speculated pairings are Midas Cichlid (Amphilophus Citrinellus) with the Redhead Cichlid (Paratheraps Synspilum). One of the more wild theories is the Severum (Heros Severus) with the Red Devil Cichlid (Amphilophus Labiatus). Blood Parrots have a round body, a beak shaped head with an upside down triangle mouth. They are often seen in bright orange in coloration, but seen in other colors such as red, yellow, brown, and tan. A further developed variety is the Convict Parrot Cichlid, which is also called the Jellybean Parrot or Bubble Gum Parrot. This is actually a double hybrid fish. It is a cross between a female hybrid Blood Parrot and a pink male Convict Cichlid Archocentrus (Cichlasoma) nigrofasciatus. Blood Parrots have reportedly been crossed with other cichlid species such as the Severum and the Texas Cichlid. So there may be other new varieties showing up down the road ...
Sensory adaptation to the local environment can contribute to speciation. Aquatic environments are well suited for studying this process: The natural attenuation of light through water results in heterogeneous light environments, to which vision-dependent species must adapt for communication and survival. Here, we study visual adaptation in sympatric Pundamilia cichlids from southeastern Lake Victoria. Species with blue or red male nuptial coloration co-occur at many rocky islands but tend to be depth-differentiated, entailing different visual habitats, more strongly at some islands than others. Divergent visual adaptation to these environments has been implicated as a major factor in the divergence of P. pundamilia and P. nyererei, as they show consistent differentiation in the long-wavelength-sensitive visual pigment gene sequence (LWS opsin). In addition to sequence variation, variation in the opsin gene expression levels may contribute to visual adaptation. We characterized opsin gene ...

ISSN 0962-1083. 25(24), s 6143- 6161 . doi: 10.1111/mec.13767 Show summary How variation in the genome translates into biological diversity and new species originate has endured as the mystery of mysteries in evolutionary biology. African cichlid fishes are prime model systems to address speciation-related questions for their remarkable taxonomic and phenotypic diversity, and the possible role of gene flow in this process. Here, we capitalize on genome sequencing and phylogenomic analyses to address the relative impacts of incomplete lineage sorting, introgression and hybrid speciation in the Neolamprologus savoryi-complex (the Princess cichlids) from Lake Tanganyika. We present a time-calibrated species tree based on whole-genome sequences and provide strong ...
The Nile tilapia, Oreochromis niloticus, is a tropical fish species of commercial importance in both aquaculture and in the wild. It plays a great role in human nutrition and food security. River Ruiru is one of the rivers faced with pollution from nearby industries. It is inhabited by various species of fish such as tilapia and common carp, which, may be harvested by surrounding communities for food. High levels of heavy metals disrupt normal reproductive process in fish. Besides, it has been reported that edible fish contaminated with heavy metals has deleterious effects on the health of humans and other animals that consume them. There is no documented information on the association between heavy metals and the reproductive biology of Oreochromis niloticus in River Ruiru. This study was aimed at assessing the level of heavy metals in fish ovaries and their association with selected reproductive parameters in the reproductive cycle of O. niloticus. Fish samples were collected monthly, for 8 ...
This study aimed to evaluate the efficacy of three methods of slaughter of Nile tilapia (Oreochromis niloticus) and the quality of frozen fillets. This research was performed in two steps consisting in applying the methods of killing by electric shock (ChE), gas mixture (CO2N) and hypothermia (AG). The first step was analyzed whole fish cold, evaluated indices of rigor mortis, degradation of ATP, pH, N-BVT NNP, muscle contraction, and texture instrumental color and sensory evaluation. Fish killed by ChE showed a delay in the time of entry into rigor mortis, this same treatment showed R2 0.92 in the interaction between the degradation of ATP and rigor. The pH was affected (p, 0.05) by treatments and time. The highest values occurred in the BNV slaughter by ChE. Slaughter presented by AG 452 mg NNP/100g. The storage time caused a slight decrease in instrumental texture slaughter by ChE. A L* increased with time for slaughter for ChE and CO2N. Sensory analysis showed an R2 0.94, 0.98 and 0.96 for ...

The bacteriological quality of both wild and cultured Nile Tilapia, Oreochromis niloticus, sourced in some area of Ibadan, Southwest, Nigeria was studied. Bacteria flora of the skin and stomach of fish samples were examined and compared statistically (t-test independent). The resistance of bacterial isolates to commonly used antibiotics was also studied. Total aerobic bacteria count [colony forming unit: CFU = 159.50.13 ± 72, t < 0.01] with significant difference in the skin and Enterobacteriaceae count [(CFU) = 74.08 ± 5.55] with significant difference in the stomach were obtained in the Nile tilapia. The bacteria in the genera Staphylococcus, Escherichia, Proteus, Bacillus, Klebsiella, Micrococcus, Serratia, Pseudomonas, Salmonella and Streptococcus were isolated and have been proven to be of great public health significance. About 87.5% of the tested isolates were resistant to augmentin, 83.33% to cotrimoxazole and nalidixic acid. In addition, 79.17% of the isolates were resistant to tetracycline,

Biological Treatment of Broad Bean Hulls and its Evaluation through Tilapia Fingerlings (Oreochromis Niloticus) Feeding Abstract.
The diversity of habitats occupied by cichlids is matched by the number of mating systems they employ. In fact, the local ecological conditions are an important indicator of the mating system used, which may vary within the same species. The most primitive condition is monogamy, with males and females essentially monomorphic, excepting some coloring details. Courtship rituals and parental care are common among monogamous pairs. Some cichlids are polygynous: males fertilize the eggs of more than one female. In this system, males might defend a territory that females visit to spawn (only once during the season), two females may defend a territory overlapping that of a male (bigamy), or a male may dominate a harem of multiple females. Cichlids also employ polyandry, in which females mate with several males. In one extraordinary case, sex roles are essentially reversed. Sarotherodon melanotheron males nurture eggs and fry in the mouth for 15 days after spawning, while females are capable of spawning ...

[online]. 2016, vol.87, n.3, pp.1002-1009. ISSN 2007-8706. The aim of this study was to investigate monogenean fauna in gills of Geophagus camopiensis, Pterophyllum scalare, Satanoperca jurupari, and Satanoperca acuticeps in a tributary from the Amazon River system in Brazil. A total of 2,148 monogenean specimens were collected from 140 fish examined from March 2012 to March 2013, and 84.3% of these fish were parasitized by 1 or more species. Such monogeneans were: Sciadicleithrum geophagi, Sciadicleithrum juruparii, Gussevia spiralocirra and Gyrodactylus sp. However, only G. camopiensis was parasitized by more than 1 species of monogenean, while S. jurupari and S. acuticeps were parasitized by the same species. Prevalence, mean intensity and mean abundance varied among ...

The Apistogramma cacatuoides is commonly known as the Cockatoo Dwarf Cichlid or Big Mouth Apistogramma. The Apistogramma originates in the streams and backwaters of South America. This strain has been selectively bred for its brilliant orange coloration. The body of these fish is elongated, with a prominent dorsal fin. The rear part of the dorsal fin, as well as the tail, has a striking orange coloration. The Dwarf Cockatoo Cichlid should be kept in an aquarium that is 30 gallons minimum, with densely planted groupings. They require plenty of open swimming areas but also need hiding places. A fine gravel to sand substrate is recommended. Although a semi-aggressive fish, the Apistogramma is also timid and should not be housed with large, aggressive fish. They require good water conditions, and regular water changes are a must. The Dwarf Cockatoo Cichlid is an egg layer that prefers to spawn in caves. Once the female has laid her eggs, the male will follow to fertilize them. After fertilization, ...
Formaldehyde (HCHO) was recently detected at concentrations above the cancer benchmark in 90% of 60 000 surveyed United States census tracks. Formaldehyde leaches into and mixes with water extremely well, exposing aquatic life. Further, formaldehyde is used therapeutically in aquaculture to remove external protozoa and other parasites from fish. The present study was undertaken to determine if sub-acute HCHO causes immunologic changes in tilapia Oreochromis niloticus. Fish were exposed to 0, 50, or 150 ppm of HCHO. Immune parameters examined included blood hematology, spleen/body weight ratio, spleen and pronephros total cellularity, leukocyte blastogenesis, and natural killer cell cytotoxicity. Organ/body weight ratios and total cellularity were not different from controls. Similarly, mitogen response and natural killer cell function were unchanged. Peripheral blood lymphocytes decreased as HCHO exposure increased. Formaldehyde exposure also decreased the number of progenitor cells in the fish ...

Abstain from Feeds with discus meal because discus fish does not easily digest them. Salt is the most misused and overused chemical in the discus fishroom. [STEP 2] - Perform water changes of 35% daily. Keep your discus away from any form of stress, as listed above. [STEP 5] - Use of Epsom salt for relaxation of the muscle of the fish. [STEP 4] - Feed Your Discus Anti-bacterial Fish Food. Keep in mind that once you add Epsom salt to the tank that it will stay until you do a water change. Epsom salt (magnesium sulfate) is a laxitive. NOTE: Epsom salt will increase the discus fish metabolic rate which will help them quickly get everything out of them, so you will normally see poops increment in your tank. Epsom salts do not go away once added to the tank and will stay in the water until you change it, so you dont need to replace it unless you do a water change. Description. You have 5 days from the first time he begins headstanding to cure him if you lower the water level, 3 days if you do not. ...
B.1. INTRODUCTION. The Nile perch (Lates niloticus),2 was reportedly transplanted into the Ugandan waters of Lake Victoria in the late 1950s and early 1960s (EAFFRO 1960; Hamblyn 1960).3 The question of whether or not to introduce this large, predatory fish sparked considerable controversy (Anderson 1961; Fryer 1960; Jackson 1971; Ogutu-Ohwayo 1985; Ribbink 1987; van Someren 1963). Opponents pointed out that such a step made little ecological sense: the theoretical potential sustained harvest from predatory fish (at the top of the food/energy pyramid) is significantly less than from their prey (typically represented at the middle or lower levels of the pyramid). Others argued that Nile perch, feeding on the huge but relatively unexploited and unpopular species stocks of haplochromine cichlids, would eventually provide the Lake with an important new fishery. Indeed, certain reports give the impression that Lates was first introduced with just such an objective in mind (e.g. Acere 1985). However, ...

Identification and expression profiles of multiple genes in Nile tilapia in response to bacterial infections. Veterinary Immunology and Immunopathology. 144:111-119. Interpretive Summary: To understand how Nile tilapia responds to bacterial infection at molecular level, a subtractive library was constructed. A total of 31 unique genes were identified from the subtractive library. Nine of the 31 ESTs were significantly induced in Nile tilapia at 6h post infection with A. hydrophila at an injection dose that caused ~20% mortality. Of the nine induced genes, four were also significantly induced in Nile tilapia at 6h post infection with A. hydrophila at an injection dose that caused ~60% mortality. Of the four genes induced by A. hydrophila at both injection doses, three were also significantly induced at 6h post infection with Streptococcus iniae at dose that caused ~70% or ~30% mortality. The ...

The Nile tilapia, a fish commonly found in our marketplace that makes savory dishes, is not only a source of food but may be useful in rthew management of deseases.
As we mentioned above, the diet for a discus should be varied in order to meet all its nutritional requirements.. One of the most favorite foods of discus fish is bloodworms. They are rich in protein, fiber, and fats thus providing the fish necessary nutrients for proper functioning.. The bloodworms can be administered live or frozen. However, we strictly recommend going for the frozen version as live tubifex worms contain the risk of parasites and food poisoning.. White worms are another popular food for the discus. They are full of proteins and even the fussy eaters enjoy them. They also make a good diet for the breeding discus, as they are high in proteins and allow the fish to quickly add size and mass.. The white worms can be easily cultivated at home using a non-transparent plastic container and a layer of peat soil. You can feed the white worms anything from rice flour and bread soaked in water to pasta and scraps of non-citrus fruits and vegetables.. Once you meet all the requirements of ...

AU - Siharath, Kimmakone. AU - Richman, N. Harold. AU - Bern, Howard A.. AU - Grau, E. Gordon. PY - 1997/4. Y1 - 1997/4. N2 - To date, growth hormone (GH) is known to contribute to seawater adaptation only in salmonid fishes (primitive Euteleostei). Accordingly, the effects of homologous GH and two forms of homologous prolactin (PRL177 and PRL188) on hypoosmoregulatory ability and gill Na+,K+-ATPase activity in a more advanced euryhaline cichlid fish, the tilapia (Oreochromis mossambicus), were examined. Following adaptation of hypophysectomized fish to 25% seawater for 3 weeks, fish were given four injections of hormone or vehicle. They were then exposed to 100% seawater for 12 hr and examined for changes in plasma osmolality. Tilapia GH (0.02 and 0.2 μg/g) significantly improved the ability of ...
Results:. The results indicated that increasing the enzyme concentration produced an increase in the DH and in the reaction rate, while increasing the substrate concentration produced a decrease in both parameters. For this reason, a mathematical model was adjusted for the inhibition of substrate from the exponential kinetic equation d(DH)/dt = a*EXP[-b*(DH)] to explain the behavior of the DH as a function of substrate concentration in this hydrolytic process. The parameters a and b were estimated from a nonlinear regression. Based on these results, the reaction constants were determined as Ks = 456.75 g L-1, K2 = 1.2191 min-1, Kd = 0.2224 min-1, KM = 1.8963 and K3 = 0.1173 L g-1 min-1, which allowed the generation of a good correlation between the predicted and experimental values at the different evaluated operating conditions. This correlation was supported by a low average relative error (ARE) of 3.26%. ...

The frequent bioaccumulation of pharmaceuticals in the aquatic ecosystem has raised a concern about their possible ecotoxicological consequences. DNA damage, haematological changes and activities of oxidative stress enzymes in Nile tilapia, Oreochromis niloticus in response to diclofenac (DCF) exposure were investigated for up to 60 days at the concentrations of 0.17, 0.34 and 0.68mgL−1 in the fis ...
Osteosarcoma (OS) is a common malignant bone cancer. The relatively high density of a persons bone structure means low permeability for drugs, and so finding drugs that can be more effective is important and should not be delayed. MSPs are marine antimicrobial peptides (AMP) and natural compounds extracted from Nile tilapia (Oreochromis niloticus). MSP-4 is a part of the AMPs series, with the advantage of having a molecular weight of about 2.7-kDa and anticancer effects, although the responsible anticancer mechanism is not very clear. The goal of this study is to determine the workings of the mechanism associated with apoptosis resulting from MSP-4 in osteosarcoma MG63 cells. The study showed that MSP-4 significantly induced apoptosis in MG63 cells, with Western blot indicating that MSP-4 induced this apoptosis through an intrinsic pathway and an extrinsic pathway. Thus, a pretreatment system with a particular inhibitor of Z-IETD-FMK (caspase-8 inhibitor) and Z-LEHD-FMK (caspase-9 inhibitor)

Microscopic investigation sometimes reveals bacterial and/or parasitic infections and in some cases, these infections, like bacterial infections, are secondary.. Sometimes, this syndrome appears when low atmospheric pressure occurs in combination with high humidity, especially for newly imported fish.. COMPLICATION: In some cases, by placing a discus or angel fish from different places of origin in the same row (fish house), or mixing them together in an aquarium makes them sick, especially if one is from Asia and the other is from Europe; for some reason, combining the two places of origin raises the risk for this pest. Fish originating from the same town or province have less or no risk.. This syndrome has not yet been scientifically studied. The symptoms look like an allergic reaction, what with the slimy reaction of the skin and gills that produce excessive mucus. Many of the discus or angel fish are raised in specific, enclosed systems without any contact with other foreign discus or ...

  • We address the diversity of two species groups of the cichlid genus Gymnogeophagus in the Middle Paraná basin using molecular phylogeography and traditional morphological characters and conclude that they are composed of a higher diversity of endemic species than previously thought. (
  • This book is an update of all the knowledge that they have accumulated during their forays in the Grande Ile, in which the diversity of cichlids was found to be much higher than previously believed. (
  • We address this issue in a lineage of ray-finned fishes that is well known for its ecological and functional diversity-African rift lake cichlids. (
  • Such is the diversity of species, breeding habits and feeding that it becomes necessary to set up different groups of Cichlids in different tanks. (
  • The hotspots of cichlid diversity are the large East African lakes, which contain hundreds of endemic species. (
  • Cichlids provide the best opportunity to examine the evolution of parental care in fishes, as they show quite a bit of diversity in caring for their offspring. (
  • Some of these include African Cichlids, American Cichlids, Dwarf Cichlids or Discus. (
  • We further demonstrate that the endemism in Gymnogeophagus shows a high degree of biogeographical congruence with other sympatric cichlid genera. (
  • This novelty is mechanically integrated with the upper jaw, appears to be under directional selection, and is found in one of the most ecologically successful cichlid lineages. (
  • The Middle Paraná basin has up to 27 globaly endemic species of cichlid fishes in three genera and 21 of these species are endemics of single tributaries of the Middle Paraná. (
  • The first group, the so-called five-spotted cichlids (including H. elongatus , H. faciatus and H. frempongi ), would remain in the genus Hemichromis , while the rest, the true jewel cichlids, would be moved to their own genus. (
  • [6] A comprehensive study of the genus also points to the existence of two undescribed species of jewel cichlids in the Guinea region . (
  • One particularly important example of this is the Amazonian cichlid genus Cichla , the species of which are collectively known in Brazil as tucunaré. (

  • Rift lake cichlids have a rather complex behavior, primarily expressed through color and movement. (
  • Descendants of the genetically diverse hybrid population colonised the lake and, within the evolutionarily short period of several thousand years, diverged to form around 500 new (endemic) cichlid species, with a wide variety of ecological specialisations. (
  • The Tiger Oscar is a Cichlid who is silver-blue with dark tiger stripes and a splash of tiger-orange coloring when they mature. (
  • While most cichlids are not well suited for a community tank, if a male and female pair of this specific type are placed in a community tank, they generally will do well. (
  • Most cichlids come to recognize who feeds them and often refuse to come out when unfamiliar people approach the tank. (
  • Jewel cichlids are neither suited to beginners, nor the usual community tank. (
  • Cichlids of 6 inches (15 cm) or less need at least a 20-gallon tank. (
  • Cichlids up to 8 inches (20 cm) long need at least a 29-gallon tank. (
  • If you plan to have multiple cichlids, follow this formula to determine whether the tank should be even larger. (
  • Cichlids also like to hide, so put several cave structures in the tank. (

  • Setting up your tank system in preparation for breeding Convict Cichlids is the first step. (
  • Once the Convict Cichlids are inside the tank, make sure that the water temperature does not exceed 82 degrees Fahrenheit. (
  • Always try to choose a tank with the largest possible surface area and volume as most cichlids grow quite large. (
  • The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. (
  • That said, I primarily use flake for fry and juvenile cichlids and for my livebearers. (
  • These striking phenotypic similarities among cichlid fishes from different species flocks that have evolved in parallel make the study of the underlying genetic architecture of cichlids particularly interesting. (
  • The midas cichlid (pronounced "sic-lid") is found nowhere else in the world. (
  • It looks almost identical to the red devil cichlid, but the midas cichlid is a totally different species. (
  • The midas cichlid exhibits sexual dimorphism whereas most other members of the family do not. (

  • These findings have important implications for understanding the genetic regulation of opsin expression and raise many interesting questions about how the cichlid visual system develops. (
  • Experiments with one cichlid, Archocentrus centrarchus , have revealed that recorded sounds (produced during aggressive displays) evoked an aggressive response. (
  • The firemouth is one of the more passive Cichlids as Cichlids go, so if mixing them with other Cichlids, you should introduce the least aggressive ones first and the next least aggressive next, and so on. (
  • cichlids are aggressive and unpredictable by nature. (
  • Bug Bites Cichlid Formula is designed to provide for the often active and aggressive lifestyle of Cichlids, as well as their high growth rate. (
  • Our study provided evidence for differences in the anatomy of fin elongation and suggested gene regulatory divergence between the two cichlid species. (
  • My next cichlid was an Apistogramma agassizii, which I still have today. (
  • However, a few traits in cichlids lend themselves to genetic study because they are associated with a fewer number of genes with larger effects. (
  • In this new study, the researchers made crosses between cichlids with markedly differently traits and then analyzed the progeny for genetic differences. (
  • A team of Basel researchers jointly lead by Prof. Walter Salzburger from the Department of Zoology and Prof. Markus Affolter from the Biozentrum at the University of Basel now clarified the genetic and developmental origins of an evolutionary innovation in African cichlids. (
  • First, we review recent advances in understanding adaptive radiation in cichlid fishes using genetic, genomic and transcriptomic approaches. (
  • This rapid evolution was facilitated by earlier hybridisation between two distantly related cichlid species from the Upper Nile and Congo drainage systems, scientists have discovered. (
  • It was known that cichlids were a biologically important group, being a good example of large-scale adaptive radiation and parallel evolution, but there had been no elucidation at the molecular level. (
  • Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. (
