Effect of low ambient mineral concentrations on the accumulation of calcium, magnesium and phosphorus by early life stages of the air-breathing armoured catfish Megalechis personata (Siluriformes: Callichthyidae). (1/338)

The accumulation of calcium, magnesium and phosphorus was measured during an 8-week period in the early life stages of the air-breathing armoured catfish Megalechis personata acclimated to low-mineral fresh water (0.073 mmol l-1 calcium, 0.015 mmol l-1 magnesium, <0.001 mmol l-1 phosphate) and high-mineral fresh water (0.59 mmol l-1 calcium, 1.94 mmol l-1 magnesium, <0.001 mmol l-1 phosphate). The fish accumulated calcium twice as fast and phosphorus 1.5 times as fast in low-mineral fresh water (LMF) as in high-mineral fresh water (HMF), while the rate of accumulation of magnesium did not differ in LMF and HMF. The difference in the rates of accumulation of calcium and phosphorus between LMF and HMF was independent of the growth performance (food intake) in LMF and HMF. The mineral content of young M. personata from natural swamps and rainforest creeks in Suriname followed the LMF accumulation curves. The transition from aquatic respiration to bimodal respiration in the third week after hatching did not affect rates of mineral accumulation. The high rates of accumulation of calcium and magnesium of M. personata in LMF of 654 and 58 micromol h-1 kg-1, respectively, exceed the rates of uptake of calcium and magnesium of teleosts reported in the literature. The high rates of mineral accumulation in the early life stages of M. personata reflect the exponential growth during the first 8 weeks after hatching and the requirements of the juveniles while building their dermal armour. M. personata is well-adapted to neotropical fresh waters with an extremely low mineral content. The accumulation of calcium and phosphorus is discussed in relation to the function of the bony armour of M. personata.  (+info)

Isolation of a single carboxyl-carboxylate proton binding site in the pore of a cyclic nucleotide-gated channel. (2/338)

The pore of the catfish olfactory cyclic nucleotide-gated (CNG) channel contains four conserved glutamate residues, one from each subunit, that form a high-affinity binding site for extracellular divalent cations. Previous work showed that these residues form two independent and equivalent high-pKa (approximately 7.6) proton binding sites, giving rise to three pH-dependent conductance states, and it was suggested that the sites were formed by pairing of the glutamates into two independent carboxyl-carboxylates. To test further this physical picture, wild-type CNG subunits were coexpressed in Xenopus oocytes with subunits lacking the critical glutamate residue, and single channel currents through hybrid CNG channels containing one to three wild-type (WT) subunits were recorded. One of these hybrid channels had two pH-dependent conductance states whose occupancy was controlled by a single high-pKa protonation site. Expression of dimers of concatenated CNG channel subunits confirmed that this hybrid contained two WT and two mutant subunits, supporting the idea that a single protonation site is made from two glutamates (dimer expression also implied the subunit makeup of the other hybrid channels). Thus, the proton binding sites in the WT channel occur as a result of the pairing of two glutamate residues. This conclusion places these residues in close proximity to one another in the pore and implies that at any instant in time detailed fourfold symmetry is disrupted.  (+info)

Protein kinase Cbeta and delta selectively phosphorylate odorant and metabotropic glutamate receptors. (3/338)

Recombinant protein segments from a metabotropic glutamate receptor and from an odorant receptor were used as substrates in protein kinase C phosphorylation assays. Protein kinase Cbeta and delta phosphorylated an intracellular consensus phosphorylation site in the metabotropic glutamate receptor. Only protein kinase Cdelta phosphorylated a novel extracellular consensus phosphorylation site in the odorant receptor. These results suggest differential regulation of these receptors by protein kinase C isotypes.  (+info)

Influence of the mu-chain C-terminal sequence on polymerization of immunoglobulin M. (4/338)

Immunoglobulin (IgM) is found in various states of covalent polymerization (microL)n, where n is typically 8, 10, or 12. The usual form of IgM of bony fish is tetrameric (8 microL units) as compared to the pentameric form (10 microL units) observed in cartilaginous fish and mammals. Two hypotheses were tested in this study. First, that the length of the mu-chain C terminus following Cys575 determines whether an IgM polymerizes as a tetramer or as a pentamer. This was tested by examining the covalent polymerization state of mouse IgM mutated to contain a series of mu-chain C-termini from bony and cartilaginous fish. The results proved this hypothesis wrong: mouse IgM bearing the C-terminal sequence of shark, salmon and cod mu-chain behaved identically to native mouse IgM, forming predominantly (microL)10 and (microL)12 forms. The second hypothesis was that an additional Cys residue near the C terminus of the mu-chain is responsible for the multiple covalent structures seen in IgM of the channel catfish. The addition of a catfish C terminus to the mouse mu-chain resulted, as predicted, in the production of a series of covalently bonded forms, with the major species being (microL)4. When a Ser-Cys unit was removed from the catfish C terminus added to the mouse mu-chain, this resulted in production of IgM indistinguishable in structure from that of wild-type mouse IgM.  (+info)

Zebrafish leopard gene as a component of the putative reaction-diffusion system. (5/338)

It has been suggested, on a theoretical basis, that a reaction-diffusion (RD) mechanism underlies pigment pattern formation in animals, but as yet, there is no molecular evidence for the putative mechanism. Mutations in the zebrafish gene, leopard, change the pattern from stripes to spots. Interestingly each allele gives a characteristic pattern, which varies in spot size, density and connectivity. That mutations in a single gene can generate such a variety of patterns can be understood using a RD model. All the pattern variations of leopard mutants can be generated in a simulation by changing a parameter value that corresponds to the reaction kinetics in a putative RD system. Substituting an intermediate value of the parameter makes the patterns similar to the heterozygous fish. These results suggest that the leopard gene product is a component of the putative RD mechanism.  (+info)

Tandem repeat structure of rhamnose-binding lectin from catfish (Silurus asotus) eggs. (6/338)

The primary structure of catfish (Silurus asotus) egg lectin (SAL) was determined. SAL cDNA contained 1448-bp nucleotides and 308 amino acid residues, deduced from open reading frame. The SAL mature protein composed of 285-amino acid residues was followed by a predicted signal sequence having 23 residues. The mRNA of SAL was found to be expressed in eggs, but not in liver. SAL is composed of three tandem repeat domain structures divided into exactly 95 amino acid residues each, and all cysteine positions of each domain were completely conserved. Sequence homologies between the three domains, termed D1 (1-95), D2 (96-190) and D3 (191-285), were as follows; D1-D2, 28%; D2-D3, 33%; D1-D3, 43%. Two conserved peptide motifs, -(AN)YGR(TD)S(T)XCS(TGR)P- and -DPCX(G)T(Y)KY(L)-, appear to exist at the N- and C-terminal regions of each domain, respectively. The kinetic parameters of SAL obtained by measuring surface plasmon resonance were as follows: K(a) (M(-1)) for neohesperidosyl-BSA, 7. 1 x 10(6); for melibiosyl-BSA, 4.9 x 10(6); and for lactosyl-BSA, 5. 2 x 10(5). These results show that RBLs including SAL comprise a family of alpha-galactosyl binding lectins having characteristic tandem repeat domain structures.  (+info)

Pivotal role for the cytoplasmic carboxyl-terminal tail of a nonmammalian gonadotropin-releasing hormone receptor in cell surface expression, ligand binding, and receptor phosphorylation and internalization. (7/338)

The gonadotropin-releasing hormone receptor (GnRH-R) of the African catfish couples to phospholipase C and belongs to the large family of G protein-coupled receptors. We recently demonstrated that removal of the carboxyl-terminal tail (S331-Q379) from the catfish GnRH-R results in a loss of agonist binding; the current study sought to define more precisely the role of this region in receptor function. Progressive truncations of the carboxyl-terminal tail decreased cell surface expression detected by either enzyme-linked immunosorbent assay or agonist-binding. The two most truncated receptors (stop331 and stop337) showed no binding but were detected at the cell surface by enzyme-linked immunosorbent assay. All receptors able to bind agonist were also able to activate phospholipase C. The catfish GnRH-R was phosphorylated after agonist-occupation and use of truncated mutants showed this phosphorylation to be within the carboxyl-terminal tail. Furthermore, studies with S356A, S363A and SS356,363AA mutant receptors demonstrated that Ser363 is a major site of agonist-induced phosphorylation. The absence of this phospho-acceptor site markedly impaired agonist-mediated receptor internalization. In addition, both, Ser363 and the last 12 residues of the tail (not containing Ser363) were shown to be important for beta-arrestin-dependent internalization. These observations are relevant to the regulatory function of the carboxyl-terminal tail of G protein-coupled receptors in general and are particularly intriguing given the absence of this region in mammalian GnRH-Rs.  (+info)

Inhibitory and stimulatory interactions between endogenous gonadotropin-releasing hormones in the African catfish (Clarias gariepinus). (8/338)

In the brain of all vertebrate classes, chicken (c) GnRH-II ([His(5), Trp(7),Tyr(8)]GnRH, cGnRH-II) is expressed in the mesencephalon. In addition, at least one other form of GnRH is expressed in the preoptical area/hypothalamus. In the human pituitary stalk and the mouse median eminence, cGnRH-II is present together with mammalian GnRH. Similarly, in the pituitary of several teleost fish (e.g., goldfish and eel, but not salmon or trout), a teleost GnRH is found together with cGnRH-II. These GnRHs are not colocalized in the same cells. Hence, these GnRH peptides may differentially regulate gonadotropin secretion and, in addition, may exert their effects simultaneously. The current study therefore investigated the effects of combinations of the two forms of GnRH present in the African catfish (Clarias gariepinus) pituitary-cGnRH-II and catfish GnRH ([His(5),Asn(8)]GnRH, cfGnRH)-on the cytosolic free calcium concentration ([Ca(2+)](i)) in single, Fura-2-loaded catfish gonadotrophs, as well as their effects on both in vitro and in vivo LH secretion. Both inhibitory and stimulatory effects of combinations of cfGnRH and cGnRH-II on [Ca(2+)](i) were observed, which were mirrored by their effects on both in vitro and in vivo LH secretion. The following pattern became apparent. The effect of intermediate or maximal effective cfGnRH doses was inhibited by the simultaneous presence of subthreshold or borderline effective cGnRH-II doses. Conversely, subthreshold or borderline effective concentrations of cfGnRH enhanced the effects of intermediate and maximal concentrations of cGnRH-II. In addition, combinations of cfGnRH and cGnRH-II concentrations that were equally active when tested separately showed an additive effect. The observed interactions between the two GnRHs may be of particular physiological relevance in the control of seasonal LH levels in the African catfish, as well as in other teleost species. Moreover, the occurrence of mutual inhibitory and stimulatory interactions between endogenous GnRHs may be a widespread aspect of GnRH action in vertebrates.  (+info)

The present study demonstrates that all three pathways for urea production, argininolysis, uricolysis and the OUC, are expressed during early development of C. gariepinus. Furthermore, the present finding (Fig.2) that urea accumulates in C. gariepinus larvae also suggests that the relatively high rates of urea excretion observed previously (Terjesen et al., 1997) represent metabolically produced urea. When the excretion data of Terjesen et al. (Terjesen et al., 1997) are employed, it can be estimated that urea accumulation accounts for less than 10% of total urea production (urea-N accumulation + excretion). Nevertheless, urea-N concentrations in fed C. gariepinus larvae are higher than in adult C. gariepinus tissues (Fig.2B), and two- to 10-fold higher than in rainbow trout and Atlantic cod larvae at first-feeding (Wright et al., 1995; Chadwick and Wright, 1999).. This is the first study to report expression of the uricolytic enzymes in early life stages of a teleost. Recently, Vigetti et al. ...

The supercritical carbon dioxide extraction (SC-CO2) of fish oil was studied using the viscera and skin of African catfish as a raw material and the CO2 as supercritical fluid solvent. A central composite design of response surface methodology (RSM) was employed to optimize the SC-CO2 extraction variables. The response variable (Y) oil yield was executed against the four independent variables namely pressure, temperature, flow rate and the soaking time. The statistical analysis showed, pressure was the most significant linear factor on oil yield. Furthermore, the oil yield was varied with the interaction effects of pressure, temperature and flow rate. Optimum points were obtained within the studied variables range at 65°C temperature, 35 MPa pressure, 2.6 mL/min flow rate and 3.6 h soaking time with maximum oil yield 66.96 and 40.6% from viscera and skin, respectively. The principal fatty acids in terms of concentration were oleic and docosahexaenoic acids respectively. The main objective of ...

An investigation was conducted to identify the allochthonous microbiota (entire intestine) and the autochthonous microbiota in proximal intestine (PI) and distal intestine (DI) of four species of Indian air-breathing fish (climbing perch; Anabas testudineus, murrel; Channa punctatus, walking catfish; Clarias batrachus and stinging catfish; Heteropneustes fossilis) by PCR based denaturing gradient gel electrophoresis (DGGE). High similarities of the allochthonous microbiota were observed between climbing perch and murrel, walking catfish and stinging catfish, indicating similar food behavior. The autochthonous microbiota of PI and DI from climbing perch and murrel revealed more similarity, than the result obtained from walking catfish and stinging catfish. The autochthonous microbiota of climbing perch and murrel were similar with regard to the allochthonous microbiota, but no such similarity was observed in case of walking catfish and stinging catfish. The fish genotype and intestinal bacteria ...
ABSTRACT. Clarias gariepinus rearing is mostly done with intensive systems that use a lot of commercial feed. The price of raw material for the feed lipid source which is currently the main source of fatty acids in freshwater fish feed continues to increase and compete with human needs. Rubber seed oil (RSO) is considered feasible to be an alternative. This study aimed to evaluate the use of heated RSO as alternative lipid source in C gariepinus feed. The results of this study indicated that heating could reduce HCN levels in RSO by 95%. Even after heated RSO was inserted into the feed formulation there is still HCN in feed, however it did not affect the survival rate of C. gariepinus statistically. Heated RSO based feed shows a specific growth rate that was higher than non-heating RSO-based feed. Feeding with heated RSO also did not affect nutrient retention in C. gariepinus. This also followed by blood profile, blood chemistry and body fatty acids profile, MDA levels and SOD levels which were ...

Introduction. To date, approximately 200 species of piscine trypanosomes are known (Gupta & Gupta 2012). In nature, trypanosome infections are common, especially where the leech vector is abundant. The effect of a trypanosome infection depends solely upon the hosts energy resources, and the impact ranges from physiological (Tandon & Chandra 1977), metabolic, pathological (Lom & Dykova 1984), biochemical (Gupta & Gupta 1986) and asymptomatic, to behavioural anomalies and syndromes (Barber, Hoare & Krause 2000). Haematological techniques are important for the assessment of the impact of trypanosome infections on fish health (Shah & Altindag 2004). Osman, Fadel and Ali (2009) reported that Clarias gariepinus (Burchell, 1822) infected with Trypanosoma mukasai Hoare, 1932 showed significant decreases in total serum protein, albumin, globulin levels, albumin/globulin ratios and cholesterol concentrations. These authors also noted an increase in serum aspartate aminotransferase and alanine ...

One hundred and twenty (120) fingerlings of Clarias gariepinus (mean weight: 0.96 ± 0.1g) were randomly exposed to 4 experimental treatments of petroleum, based on LC50 values (6.4mg/L of crude oil, 8.7mg/L of petrol, 8.0mg/L of kerosene and 7.8mg/L of diesel oil) and replicated thrice, to determine polycyclic aromatic hydrocarbons (PAH) in exposed fish for 96 h. There was no significant difference (P > 0.05) in total (PAHs) between crude oil (97.1 ng/uL) and diesel (97.2 ng/uL) exposed fish and also between petrol (53.2 ng/uL) and kerosene (49.6 ng/uL) exposed fish, but there was a significant difference (P < 0.05) in PAH levels of the crude oil/diesel exposed -groups of fish compared to petrol/kerosene exposed -groups of fish (97.1/97.2 and 53.2/49.6 ng/uL). Naphthalene correlated positively to benzo a anthracene (r=0.672, (P < 0.05), benzo b fluoranthene (r=0.681, P < 0.05) and chrysene (r=0.615, P < 0.05) but did not correlate to fluorene.

DISCUSSION. All water parameters analyzed were within the limits that permit normal growth and survival of silver catfish (e.g. nitrite and un-ionized ammonia levels below 1.2 mg L-1 and 0.1 mg L-1 respectively) (Lima et al. 2011, Miron et al. 2011).. According to Zaions & Baldisserotto (2000), even though silver catfish presents a marked loss of Na+ at pH 4.0, this is the acidic pH threshold for the species survival, at least for 96 h. In the present assessment this assertion was confirmed by the 0% survival of fish exposed to pH 3.8 regardless the HA concentrations. As stated by Wood & McDonald (1982), nonacidophilic species suffocate at pH levels below 4.0 due to gill structural damage, edema and mucification. Moreover, fish mortality in acid waters is largely associated with a failure to ionoregulate, especially due to stimulation of Na+ efflux (Milligan & Wood 1982).

The hybrid of channel catfish (Ictalurus punctatus) ♀ × blue catfish (Ictalurus furcatus) ♂ (C × B) is the best catfish for pond culture. The current technology, artificial fertilization and handstripping is labor intensive, time consuming, and requires sacrifice of mature 5 ~ 6 year old blue catfish males. Xenogenic catfish produced by transplanting blue catfish stem cell into the gonads of triploid channel catfish could reduce the generation interval to produce blue catfish and might result in channel catfish males that are able to produce blue catfish sperm, and increase the efficiency of C × B hybrid catfish embryo production. Gonadal cell size and type of 90 ~ 100 day - old fry (TL: 5 ~ 6 cm), two - year old juvenile (TL: 25 ~ 30cm) and mature adults (TL: 65 ~ 70 cm) blue catfish was examined. Gonads of all ages of fish contained oogonia (12 ~ 15 μm diameter, distinct nucleus 7 ~ 8 μm) and spermatogonia (12 ~ 15 μm, distinct nucleus 6 ~ 7.5 μm). Male juvenile blue catfish, which ...
Study on biotransformation of �-fatty acid from fish oil was carried out. Pseudomonas aeruginosa has been chosen to be the biocatalyst for biotransformation of w fatty acids extracted from Malaysian catfish, Clarias gariepinus. The lipid from freeze-dried catfish flesh was extracted using a modified Folch method and the mixture of chloroform and methanol was used as a solvent. The crude lipid substrate was added to the bacterial culture and incubated for 4 days. After conversion, the products were analyzed by using gas chromatography and mass spectrometer (GC-MS). The analytical result showed that several fatty acids and cholesterol were found in the product. However, the fatty acids and cholesterol contents before and after biotransformation were different. The cholesterol content increased while �-fatty acid contents decreased after biotransformation process. It can be concluded that the bacterial cells had oxidized the �-fatty acids to yield precursors which can be utilized as starting ...
Castration of the catfish Heteropneustes fossilis for different duration (up to 4 weeks) in the preparatory-prespawning phase resulted in varied effects on plasma testosterone and seminal vesicle (SV) biochemical parameters in a duration-dependent manner. Although plasma testosterone was significantly reduced at all duration of castration in comparison to sham control values, a duration-dependent increase was noticed in the castrates after week 1. SV-somatic index (SVSI) increased significantly and steadily during castration except in week 1. Concentrations of total proteins decreased initially in week 1, and increased subsequently to the sham control level in week 2 and significantly above the sham control values in weeks 3 and 4. Hexosamine concentration was significantly low in weeks 1 and 2, and was restored in weeks 3 and 4. Fructose concentration decreased significantly in weeks 1, 2 and 3, and increased significantly in week 4. In contrast, glucose concentration increased significantly in week 1,

Catfish from Lunsklip Fisheries were fed almost exclusively on untreated waste, rich in polyunsaturated fat, from the trout slaughterhouse on this farm. This waste, consisting largely of fat rich innards, was dumped into the catfish pond where it decomposed until consumed by the fish. These fish showed a high prevalence of pansteatitis as expected under such nutritional conditions, and provided the study with a positive reference population (Table 1). In the Olifants Gorge, analysis of stomach contents showed that catfish fed predominantly on fish as well as insects and small reptiles that had been washed into the river during flood conditions. On the Mozambique border where the Olifants River flows into Lake Massingir and where the sand-bottomed pools and rapids have been inundated with clay deposits, sampled catfish appeared to be feeding off the surface of the clay, and ingesta consisted of algal detritus and clay. In the Sabie River, the Sabiepoort has also been partially inundated with clay ...

Amino acid analyses and peptide mapping were performed for the four main haemoglobins from the armoured catfish Pterygoplichthys pardalis; component I, which is functionally distinct from the others, is structurally unique, whereas components II, III and IV, functionally indistinguishable, are closely related in structure. Compositional difference indices are calculated for the four components and for the two major haemoglobins from the trout Salmo irideus, and the results are discussed in terms of structural relationships and evolutionary history of fish haemoglobins. ...
We assessed the effects of body lipid content on the resting metabolic rate and specific dynamic action (SDA) of the southern catfish Silurus meridionalis. Obese and lean fish were obtained by feeding the fish with two different feeds at 27.5 degrees C for 4 weeks prior to the experiment. The fish w …
INTRODUCTION. African catfish (Clarias gariepinus) is one of many economical freshwater fishes that are cultured in Nigeria for its excellent biological characteristics such as fast growth, popular taste and high economic value. Unfortunately, high mortality acts as an important limiting factor for aquaculture businesses as result of wound and infections sustained by the fish. Wound has been defined as a disruption of normal anatomical structure and more importantly function. Therefore, healing is the complex and dynamic process that results in the restoration of anatomical continuity and function (Lazarus et al 1994).. A wound may be produced by chemical, physical, thermal, microbial or immunological action on the tissue, causing discomfort and making it more prone to infection and other troublesome complications (Ingold 1993). Wounds normally heal in a very orderly and efficient manner characterised by four distinct, but overlapping phases: haemostasis, inflammation, proliferation and ...

Ever wondered how many catfish there are? Matt Clarke has the answer. There are now over 3,000 species of catfish spanning more than 36 families, plus many more species waiting to be described. Hundreds of these are commonly kept by fishkeepers. Catfish account for one out of every 20 known vertebrate animals.. Thanks to projects such as the All Catfish Species Inventory (ACSI), which is funding research by catfish ichthyologists, descriptions of new species are at an all-time high. Among the most notable recent discoveries is Lacantunia enigmatica, which was placed in its own family.. This item was first published in the September 2009 issue of Practical Fishkeeping magazine. It may not be reproduced without written permission. ...

Molecular Phylogenetics and Evolution - in press. Abstract. Doradidae is a monophyletic catfish family endemic to continental South America, and composed of 93 valid species here placed in 31 genera. Existing phylogenetic hypotheses for Doradidae are derived from comprehensive analyses of morphological data, and a single molecular-based study on a limited subset of taxa. To provide a robust molecular phylogeny commensurate with those based on morphology, we gathered original and published sequence data for 86 species-level taxa (at least 70 valid species plus 16 new or questionably nominal species) and all genera of Doradidae, as well as ten species (9 genera) of Auchenipteridae and three species and genera of Aspredinidae as outgroups. 3011 base pairs were aligned for two mitochondrial genes (cytochrome c oxidase subunit 1, and 16S ribosomal RNA) and one nuclear gene (recombination activating gene 1), and analyzed for a total of 143 specimens (130 doradids, 10 auchenipterids and 3 aspredinids). ...
Discussion. Studies concerning the population structure of fishes are very important because they provide many elucidating answers about species ecology (Agostinho et al., 1994). Several aspects of the life strategy of the species about energy allocation for growth, reproduction or maintenance are interpreted through the analyses of population structure (Benedito-Cecílio & Agostinho, 1997). In the upper Paraná River floodplain, I. labrosus is a benthophagous species (Fugi, 1993; Fugi et al., 1996; Peretti & Andrian, 2004), living close to the bottom. Thus, the largest abundance of I. labrosus found at the Campina site could be associated with the characteristics of that site and with the feeding habit of the species. According to Holzbach et al. (2005), the largest capture of Steindachnerina insculpta, also found at the Campina site, would be related to the presence of the Cantú River mouth which has conditions that support its development, such as vast marginal vegetation, calm and clear ...
Molecular Phylogenetics and Evolution - in press. Abstract. The Loricariinae belong to the Neotropical mailed catfish family Loricariidae, the most species-rich catfish family. Among loricariids, members of the Loricariinae are united by a long and flattened caudal peduncle and the absence of an adipose fin. Despite numerous studies of the Loricariidae, there is no comprehensive phylogeny of this morphologically highly diversified subfamily. To fill this gap, we present a molecular phylogeny of this group, including 350 representatives, based on the analysis of mitochondrial and nuclear genes (8426 positions). The resulting phylogeny indicates that Loricariinae are distributed into two sister tribes: Harttiini and Loricariini. The Harttiini tribe, as classically defined, constitutes a paraphyletic assemblage and is here restricted to the three genera Harttia, Cteniloricaria, and Harttiella. Two subtribes are distinguished within Loricariini: Farlowellina and Loricariina. Within Farlowellina, the ...

Aquaculture Conference Proceedings. P. 8. Interpretive Summary: Technical Abstract: Channel catfish, Ictalurus punctatus - a leading aquaculture species in United States for past several years has declining production trends, largely due to higher cost of inputs, inefficiencies in production, and competition from lower-priced imports. With the interest of increasing the efficiency of catfish aquaculture production, channel catfish females have been crossed with blue catfish males to produce a channel x blue hybrid catfish. Hybrid catfish have higher growth rates, survival and processing yield than commonly raised channel catfish. Presently, an increasing number of catfish farmers are raising hybrid catfish in production ponds to harness the superiority of hybrid catfish. Hybrid fry production is a hormone-based synchronization ...

Life is full of risks. Getting the next meal or defending your territory can be hazardous. David McKenzie from the CNRS Montpellier, France, explains that animals gamble with fate for several reasons. Some animals have to place themselves at risk when foraging to satisfy a high metabolic rate, while others are simply bolder: and fish are no exception. McKenzie is also intrigued by air-breathing fish and was puzzled why less than 2% of fish have evolved the ability. Air is a rich source of oxygen but breathing it is risky, so it made me wonder if it might be linked to personality, says McKenzie, explaining that fish that breathe at the surface are vulnerable to predation. Knowing that Brazil is gripped by an invasion of air-breathing African sharptooth catfish (Clarias gariepinus), McKenzie decided to visit his collaborator Tadeu Rantin at the Federal University of São Carlos, Brazil, to find out whether it takes courage for the catfish to breathe air or whether they simply surface to satisfy ...

Bacterial populations in some organs, viz., liver, spleen, kidney, gill, and arborescent organ of the catfish Clarias batrachus were enumerated followed by determination of resistance for antibiotics and metals. The total viable counts in these organs, observed, were 2.24x10(4), 2.08x10(4), 1.44x10(4), 1.23x10(4), and 6.40x10(3) colony-forming units/mL, respectively. The random bacterial isolates from these fish organs showed resistance in decreasing order for colistin (98%), ampicillin (82%), gentamycin (34%), carbenicillin (28%), tetracyline (20%), streptomycin (12%), and ciprofloxacin (02%). Most of the isolates exhibited an increasing order of tolerance for the metals (microg/mL) copper (100), lead (200), manganese (400), cadmium (200), and chromium (50), with minimum inhibitory concentration (MIC) ranging from |50 to 1600 microg/mL. These observations indicate that the significant occurrence of bacterial population in organs of fish with high incidence of resistance for antibiotics and metals may
A Preliminary Study on the Effects of Hyperosmotic Stress on Plasma Levels of Thyroid Hormones in Male Catfish, Clarias gariepinus
Traditional pond-spawning, which is effectively used to produce channel catfish fry, is ineffective for consistent, large-scale production of hybrid fry because of reproductive barriers (behavioral, physiological etc.) that prevent spawning between blue and channel catfish. Although there have been reports of successful spawning in brood ponds stocked with male blue catfish and female channel catfish, the occurrence of pond-spawning is very rare and not reliable for commercial hatchery production. Unless some future development dramatically improves the spawning rate in traditional brood ponds, production of hybrid fry will depend on the use of hormones to induce ovulation (final maturation and release of eggs) in females, manual stripping of eggs, and manual fertilization of the eggs with blue catfish sperm (Tave and Smitherman 1982, Dunham et al. 2000 ...
The hybrid from the mating of a female channel catfish (Ictalurus punctatus) with a male blue catfish (Ictalurus furcatus) exhibits heterosis for various performance traits which would make it attractive to the commercial aquaculture industry. However, the widespread use of the hybrid in the aquaculture industry has been impeded by reproductive isolating mechanisms that prohibit the adequate production of fry. The primary research objective was to evaluate various genotypes of channel catfish females to determine if certain genotypes with blue catfish produced increased numbers of fry when hybridized. Fry output and other reproductive traits of seventeen genotypes of channel catfish females when crossed with blue catfish males were evaluated. The effect of crossbreeding or selection for body weight for channel catfish females was evaluated to determine heterosis, correlated responses or inbreeding depression for hybrid fry production. No clear effect of strain on percent ovulation, latency ...

Channel Catfish are widely distributed across North America and highly valued as a sport fish and for food. While most Channel Catfish fisheries are managed under liberal harvest regulations, the Red River of the North (Red River) in Manitoba, Canada is managed with restrictive harvest regulations to promote a trophy fishery. Two barriers (dams) are present on the main stem of the Red River and may fragment the population to some degree. My objectives were to: 1) analyze population dynamics of the trophy Channel Catfish population on the lower Red River, 2) compare population characteristics of Channel Catfish in selected reaches throughout the Red River in Manitoba, and 3) determine movement characteristics of Channel Catfish and the permeability of a dam on the lower Red River. We compared our results to the most recent studies on Channel Catfish in the Red River, and also to range-wide age, growth, and mortality statistics. Channel Catfish in the lower Red River commonly reached ages | 20, grew
Fishing for channel catfish (Ictalurus punctatus) is popular in Nebraska and channel catfish are the most sought after fish species in the Platte River. Anglers on the Platte River are also harvest oriented. Little is known about the effects anglers have on channel catfish population dynamics in the lower Platte River. The goal of this study was to determine if there were effects of angling on channel catfish at two high use fishing areas in the lower Platte River. My first objective was to evaluate differences in relative abundance, size structure, condition, age structure, growth, and mortality between two high use areas (near Fremont and Louisville, NE). I also used a robust design capture-mark-recapture study to estimate density and abundance of channel catfish | 200 mm within a 10-km stretch of the Platte River at each sampling site. The second objective was to assess the 5 year standardized monitoring data for spatial and temporal differences in relative abundance, size structure, condition, age

The Tiger Shovelnose Catfish (Pseudoplatystoma fasciatum) also known by tropical fish keeping enthusiasts as the Tiger Catfish, is found in various rivers and tributaries in South America. It prefers deeper waters in the main river channels but can be found in lakes, flooded forests and other freshwater areas.. The Tiger Shovelnose Catfish is long and slender with a beautiful silver coloration over its entire body. Its body is covered with black stripes and spots which give the fish a tiger like appearance, hence its name.. The Tiger Shovelnose Catfish has a long flat shaped mouth that is adorned with very long whiskers.. These catfish grow quite large in captivity (over 3 feet) and require at least a 180 gallon aquarium to keep them happy and healthy. They are active and should have a tight fitting tank cover to prevent them from jumping out of their tank.. ...
The efficacy of hydrogen peroxide in controlling mortality associated with external columnaris infections on walleye Sander vitreus (formerly Stizostedion vitreum) and channel catfish Ictalurus punctatus fingerlings was evaluated in two on-site trials. Microscopic examination of skin scrapes before treatment confirmed the presence of bacteria indicative of columnaris disease. In separate trials, walleyes (12 g) and channel catfish (2.3 g) were exposed to a total of three every-other-day hydrogen peroxide treatments of 0, 50, 75, or 100 mg/L for 60 min. Each treatment regimen was tested in triplicate, and each replicate contained 13 walleyes or 26 channel catfish. Hydrogen peroxide exposures of 50 mg/L for 60 min significantly increased walleye survival relative to that at other treatment concentrations, including the controls. Exposures of 50, 75, or 100 mg/L of hydrogen peroxide for 60 min significantly increased channel catfish survival in comparison with that of controls. These trials indicated that

Bacterial Diseases. Enteric Septicemia of Catfish (ESC) is an important infectious bacterial disease of farm-raised channel catfish. The causative agent of ESC is a gram-negative bacterial species, Edwardsiella ictaluri. While channel catfish are the most susceptible to infection, most other catfish species are also susceptible. ESC was first recognized in pond-raised channel catfish in 1976. Treatments include early intervention with approved antibiotics, restricting feed, and vaccination. While it is unclear whether these treatments are directly responsible, catfish operations are reporting decreased losses of foodfish and fry/fingerlings due to ESC.. Columnaris disease is one of the most common diseases of warmwater fish and infects at least 36 species of cultured and wild fish. While the causative bacterium has been renamed and reclassified many times, the current name is Flavobacterium columnare.. Although columnaris disease is often considered a secondary infection following periods of ...
During surveys of the trichodinid parasites in freshwater and estuarine fishes in the state of West Bengal, India five species of the genus Trichodina from the gills of host fishes were investigated and morphologically studied. Of these, four are described as new: Trichodina ahmedi sp. n. from Chanda nama, Trichodina hafizuddini sp. n. from Amblypharyngodon mola, Trichodina mossambicusi sp. n. from Oreochromis mossambicus and Trichodina heterospina sp. n. from Sardinella fimbriata. During the study period Trichodina martinkae from Clarias batrachus was also recorded for the first time in India. Taxonomic and morphometric data for these trichodinids based on wet silver nitrate impregnated specimens are presented. For each of the new species, comparisons with closely related species are provided.
Well, weve had cuckoo birds on this blog before, which most people would at least have heard of, but what about the cuckoo catfish? The cuckoo catfish, Synodontis multipunctatus, a popular ornamental fish that is somewhat well-known amongst aquarium enthusiasts. It is originally from Lake Tanganyika in Africa which is hotspot of cichlid fish biodiversity. The cuckoo catfish has a rather unusual breeding habit, it is a brood parasite of mouthbrooding cichlids found in Lake Tanganyika. Just like their bird namesake, the cuckoo catfish displaces the legitimate offspring of its host, forcing the cichlid to rear its young, and they have a rather clever way of accomplishing this. The catfish is attracted by the scent of the brooding cichlids, and as soon as they detect any such brooding cichlid in the vicinity, they race to the scene of the coupling. The catfish mob the pair of spawning cichlids and as soon as their eggs are fertilised, a mating pair of cuckoo catfish dash in, the female laying her ...

After the cleavage of disulfide bonds of macroglobulin isolated from channel catfish (Ictalurus punctatus), an electrophoretically fast-moving polypeptide, which resembled human J chain, was released. On a Sephadex G-200 column equilibrated in 5 M guanidine, the elution position of the J chain overlapped with the descending part of the L chain peak. Further purification was achieved by DEAE ion-exchange chromatography. The isolated polypeptide, which had a molecular weight of 14,800 ± 500, as determined ultracentrifugally by sedimentation equilibrium in 5 M guanidine, contained 7% carbohydrate with one residue of fucose, two of mannose, one of galactose, two of glucosamine, and one of sialic acid per chain. A comparison of catfish and human J chain amino acid analyses showed the former to have a higher content of serine, glycine, and phenylalanine and a lower content of aspartic acid, isoleucine, and arginine. Tryptic peptide maps of catfish and human J chains revealed very few common peptides. ...

Mr. Pinkney and his researchers began tracking a group of 10 brown bullhead catfish July 20, after two studies conducted over the past decade found that more than half of the catfish caught in the Anacostia River had liver tumors. I think these results indicate the seriousness of the problem in the Anacostia, Mr. Pinkney said. Tumor rates in freshwater and saltwater fish have been used as an indicator of pollution. Experts say anything over 9 percent indicates high levels of pollution. The most recent study, completed in 1996, found that 55 percent of the 60 catfish caught swimming in the Anacostia River had liver tumors. Most of the tumors were microscopic; however, some measured nearly a centimeter long, said John Harshbarger, a fish pathologist at George Washington University Medical Center, who conducted one of the studies. If 55 percent of people had liver tumors, theyd be worried about it, Mr. Harshbarger said. It would be a catastrophe. This is much the same way, except were ...

In: Proceedings, Aquaculture America Conference, March 1-5, 2010. p. 445 Interpretive Summary: Technical Abstract: Channel catfish (Ictalurus punctatus) egg masses are typically incubated in baskets that are suspended within metal troughs with water that is agitated and pushed around the eggs with paddles. A limiting factor in the successful incubation of channel catfish eggs is the absorption of oxygen to the developing embryos; sub-optimal levels of dissolved oxygen in the water results in premature hatching and increased deformities and mortality of developing catfish eggs. We designed and tested the ability of a new vertical-lift incubator (the See-Saw) to incubate channel catfish egg masses. Angle-aluminum racks were placed inside paired adjacent hatchery troughs with three hinged-lid baskets positioned in each rack. The racks were ...

Catfish is the leading aquaculture industry in the U.S. supplying approximately 45% of the total U.S. aquaculture production. The total economic value of the catfish industry is close to $3 billion annually. Aquaculture and Fisheries Center of the University of Arkansas at Pine Bluff has been involved in research for developing new products of U.S. farm-raised catfish based on analyses of consumers preferences and the technical and economic feasibility for the industry. The project focuses on important stages of the product development pathway and involved in understanding greater consumer satisfaction and excitement about U.S. farm-raised catfish. The student will develop a thesis on economics and marketing of U.S. farm-raised catfish products, specifically focusing on: (1) Understanding of changing consumers preferences for U.S. farm-raised catfish (2) Designing new U.S. farm-raised catfish products (including packaging, labeling) for different markets based on changing consumers needs in ...
Habitat fragmentation may have some significant effects on population genetic structure because geographic distance and physical barriers may impede gene flow between populations. In this study, we investigated whether recent habitat fragmentation affected genetic structure and diversity of populations of the nematode Procamallanus fulvidraconis in the yellowhead catfish, Pelteobagrus fulvidraco. The nematode was collected from 12 localities in 7 floodplain lakes of the Yangtze River. Using 11 intersimple sequence repeat markers, analysis of molecular variance showed that genetic diversity occurred mainly within populations (70.26%). Expected heterozygosity (He) of P. fulvidraconis was barely different between connected (0.2105) and unconnected lakes (0.2083). Population subdivision (Fst) between connected lakes (0.2177) was higher than in unconnected lakes (0.1676). However, the connected and unconnected lakes did not cluster into 2 clades.

Theyre all small, two inches at most, right now. The pet store told me that they would be fine living together. Is this correct? ,Well, maybe. They are all fairly aggressive fish. The Balas may nip the angel eventually. Im not sure what a silver-tipped shark is., Where can I find books on these type of fish? ,You can get some basic information from: You might also want to use, Also, I saw the same looking fish at another store and they called it a high-fin bull shark instead of a silver-tipped shark. Are they the same thing? ,I Googled both names, being unfamiliar with these common names. The silver-tipped shark that most commonly appeared was catfish and I only found saltwater bull sharks. They may very well be the same thing, but I ...

Melt the butter in a large skillet over medium heat. Add the celery, tomatoes, onions, bell peppers, jalapeños, garlic, salt, thyme, white pepper, black pepper, and paprika. Sauté, stirring frequently, until vegetables are softened, about 5 minutes. Add the white wine, bring to a boil, and simmer until the liquid has almost completely evaporated, 7 to 10 minutes. Add the stock and simmer 10 minutes more. Remove skillet from the heat and cover to keep warm.. Season the catfish with salt and pepper. On a plate or in a pie tin, whisk together the flour and cornmeal. Dredge the filets in the flour and cornmeal mix, shaking to remove excess. Heat the oil or bacon fat in a cast iron skillet over medium-high heat. Sauté the fish for 3 minutes on the rounder, fuller side, then flip the fish and add the reserved sauce. Simmer for 5 to 8 minutes, until the fish is just cooked through. Stir in the parsley, scallions, lemon juice, and basil.. To serve, gently remove the catfish with a spatula and set ...

Twelve consecutive months length frequency data (N = 6999) and FiSAT software were used in the study of the dynamics of exploited population the catfish Schilbe mystus in the Cross River Nigeria. Variation in monthly mean gonadosmtic index showed two peaks, March and September and this indicates that the species spawned twice in a year. Fitting the seasonalized von Bertalantffy growth function to our length frequency data gave the following growth parameters: L∞ = 38 cm, k = 0.33 y-1, C = 0.42 and WP = 0.96. The seasonalized length converted catch curve procedure gave the instantaneous total mortality coefficient Z = 2.97 y-1, the instantaneous natural mortality coefficient M = 0.81 Y-1, the instantaneous fishing mortality coefficient F = 2.16 y-1 and the current exploitation rate E = 0.73. This high value of E points to the high fishing pressure on the stock. The analysis of probability of capture of each length class showed that the length at first capture Lc 28.67cm. The predicted maximum ...

Adults occur in turbid estuaries, mangrove-lined lagoons and lower parts of rivers being very tolerant to changes in salinity. Found on shallow soft bottoms (Ref. 5217). Feed on a large variety of bottom-living and pelagic organisms including those found among the roots of mangroves. Reproduction occurs between September and December. A female lays 20-30 eggs, with a diameter of 10-12 mm. Males incubate the eggs in their mouth (Ref. 35381). ...

Following study of the external morphology and its unmatched variability throughout ontogeny and a re-examination of selected morphological characters based on many specimens of diplomystids from Central and South Chile, we revised and emended previous specific diagnoses and consider Diplomystes chilensis, D. nahuelbutaensis, D. camposensis, and Olivaichthys viedmensis (Baker River) to be valid species. Another group, previously identified as Diplomystes sp., D. spec., D. aff. chilensis, and D. cf. chilensis inhabiting rivers between Rapel and Itata Basins is given a new specific name (Diplomystes incognitus) and is diagnosed. An identification key to the Chilean species, including the new species, is presented. All specific diagnoses are based on external morphological characters, such as aspects of the skin, neuromast lines, and main lateral line, and position of the anus and urogenital pore, as well as certain osteological characters to facilitate the identification of these species that previously
Henneguya gurlei was isolated from Ameiurus nebulosus captured in North Carolina and redescribed using critical morphological features and 18S small-subunit ribosomal RNA (SSU rDNA) gene sequence. Plasmodia are white, spherical, or subspherical, occur in clusters, measure up to 1.8 mm in length, and are located on the dorsal, pectoral, and anal fins. Histologically, plasmodia are located in the dermis and subdermally, and the larger cysts disrupt the melanocyte pigment layer. The spore body is lanceolate, 18.2 ?? 0.3 ??m (range 15.7-20.3) in length, and 5.4 ?? 0.1 ??m (range 3.8-6.1) in width in valvular view.

Serpae tetras and Neon tetras are schooling fish, so start by adding enough of both so you get at least 6 of each. Remember, your job as an aquarist is above all else to provide good conditions for the fish you buy. Keeping fish in a too-small group is very cruel., I would particularly like fish that are beautiful and interesting to watch (I have two small daughters I would like to get interested in the world of nature). ,To be honest, six Neons and six Serpae tetras plus a loach are pretty well filling out your community tank. The only other things you might add would be a small group (4+) of Corydoras, such as Peppered or Bronze Corydoras. Do bear in mind Serpae tetras are NOT GOOD community fish -- they are semi-parasitic fish in the wild that eat the fins and scales of other, usually larger, fish. I would NEVER keep them in a community tank, though some people have gotten away with them in tanks with fast-moving tankmates. Any decent aquarium book will provide warnings about this sort of ...

(Walbaum, 1792), Atlantic salmon L., and maraena whitefish (Bloch, 1779) are farmed in aquaculture services all around the globe [1]. Their common quality may be the adipose fin, which can be found for the dorsal midline between caudal and dorsal fin, although a complete of 6000 varieties from eight purchases from the Teleostei all have an adipose fin [2]. Many artificially bred juvenile salmonids are released into sea-ranching methods every single complete year to create 4.4 million a great deal of top-class food fish [3]. Furthermore, vast amounts of salmonids are released in stock-enhancement or restocking tasks [4]. Many of these pets are tagged to monitor the achievement of these studies or indicate possession relations [5] also to determine escapees from aquaculture farms. Those are believed as ...

In the late 1900s Phengaris populations began decreasing drastically throughout Europe with the large blue butterfly being particularly affected. By the 1950s only an estimated 100,000 adults remained in Britain, and by 1978 48% of the UK's 91 known large blue populations had been lost.[11][12] Initially experts were completely baffled by the disappearance of large blues as the sites did not appear to have changed.[11] Leading hypotheses targeted collectors, insecticides, and air pollution as factors that led to the butterfly extinction.[12] A large number of projects were conducted to combat these factors, but all were completely unsuccessful.[12] The species became extinct in the Netherlands in 1964, in the UK in 1979 and also in Belgium in 1996.[7] Severe decreases in population have also occurred in Denmark, Germany, France, and Estonia.[7] Because of this decline they are being protected. A good example of this is the UNESCO Ordesa Valley in Aragon, Spain, where the butterfly's community is ...

Social behaviors of cowbird males include aggressive, competitive singing bouts with other males and pair-bonding and monogamy with females.. By manipulating demographics so juveniles only had access to females, juvenile males developed atypical social behavior; they did not engage in the typical social singing bouts with other males, did not pair bond with females, and were promiscuous. This demonstrates that there is great flexibility in the behavior of cowbirds, and that the social environment is extremely important in structuring their behavior. Adult males housed with juvenile males were shown to have greater reproductive success compared to adult males housed with other adult males. Being housed with juvenile males honed the reproductive skills of the adult males by providing them with a more complex social environment.. This finding was further studied by comparing the behaviors and reproductive success of males exposed to a dynamic flock, consisting of changing individuals, with males ...

The naked, altricial chick hatches after 11-13 days.[2] It methodically evicts all host progeny from host nests. It is a much larger bird than its hosts, and needs to monopolize the food supplied by the parents. The chick will roll the other eggs out of the nest by pushing them with its back over the edge. If the host's eggs hatch before the cuckoo's, the cuckoo chick will push the other chicks out of the nest in a similar way. At 14 days old, the common cuckoo chick is about three times the size of an adult Eurasian reed warbler. The necessity of eviction behavior is unclear. One hypothesis is that competing with host chicks leads to decreased cuckoo chick weight, which is selective pressure for eviction behavior. An analysis of the amount of food provided to common cuckoo chicks by host parents in the presence and absence of host siblings showed that when competing against host siblings, cuckoo chicks did not receive enough food, showing an inability to compete.[29] Selection pressure for ...
Many butterflies are polymorphic. P. rebeli caterpillars are polymorphic, having two strategies for living and growing underground: to exist as fast-developing larvae (FDL) or slow-developing larvae (SDL). After the ant brood adopts the FDL, which comprise approximately 25% of the total P. rebeli larvae,[23] the FDL complete growth the following spring and eclose (emerge as an adult from the pupa) in early summer to complete their life cycle.[24] The SDL, which comprise 75% of P. rebeli larvae, do not grow much during the first year, but grow rapidly during the early part of the second summer and remain a second winter within the ant colonies.[24] While both larva types ultimately form similar-sized pupae, their polymorphic growth rates could indicate alternative fitness strategies and different ways to exploit the M. schencki's food resources.[24] Other researchers hypothesize that another alternative growth strategy will evolve in the P. rebeli, in which the P. rebeli will parasitize the M. ...
