To study the complex interaction between growth and reproduction we have established lines of transgenic common carp (Cyprinus carpio) carrying a grass carp (Ctenopharyngodon idellus) growth hormone (GH) transgene. The GH-transgenic fish showed delayed gonadal development compared with non-transgenic common carp. To gain a better understanding of the phenomenon, we studied body growth, gonad development, changes of reproduction related genes and hormones of GH-transgenic common carp for 2 years. Over-expression of GH elevated peripheral gh transcription, serum GH levels, and inhibited endogenous GH expression in the pituitary. Hormone analyses indicated that GH-transgenic common carp had reduced pituitary and serum level of luteinizing hormone (LH). Among the tested genes, pituitary Ihfl was inhibited in GH-transgenic fish. Further analyses in vitro showed that GH inhibited Itil) expression. Localization of ghr with LH indicates the possibility of direct regulation of GH on gonadotrophs. We also ...

Genome duplications may have played a role in the early stages of vertebrate evolution, near the time of divergence of the lamprey lineage. Additional genome duplication, specifically in ray-finned fish, may have occurred before the divergence of the teleosts. The common carp (Cyprinus carpio) has b …
Deoxynivalenol (DON) frequently contaminates animal feed, including fish feed used in aquaculture. This study intends to further investigate the effects of DON on carp (Cyprinus carpio L.) at concentrations representative for commercial fish feeds. Experimental feeding with 352, 619 or 953 μg DON kg−1 feed resulted in unaltered growth performance of fish during six weeks of experimentation, but increased lipid peroxidation was observed in liver, head kidney and spleen after feeding of fish with the highest DON concentration. These effects of DON were mostly reversible by two weeks of feeding the uncontaminated control diet. Histopathological scoring revealed increased liver damage in DON-treated fish, which persisted even after the recovery phase. At the highest DON concentration, significantly more fat, and consequently, increased energy content, was found in whole fish body homogenates. This suggests that DON affects nutrient metabolism in carp. Changes of lactate dehydrogenase (LDH) activity in
Anoxia-tolerant vertebrates decrease their metabolic rate by 70% or more during anoxia, while the major inhibitory neurotransmitter in the vertebrate brain, GABA, increases in concentration. To test the possibility that GABA could be a mediator of anoxic metabolic depression, crucian carp (Carassius carassius L.) were given an inhibitor of GABA synthesis, isoniazid, and the rate of anoxic ethanol production (ethanol being the main end product of energy metabolism in anoxic crucian carp) as well as the rates of normoxic and hypoxic oxygen consumption were measured. Isoniazid (500mgkg−1), which significantly inhibited the anoxia-induced rise in brain GABA concentration, caused a nearly threefold increase in anaerobic ethanol production without affecting normoxic oxygen consumption. The GABA synthesis inhibitor 3-mercaptopropionic acid (3-MP, 200mgkg−1) and the GABA receptor antagonist securinine (20mgkg−1) caused similar rises in anoxic ethanol production. Nevertheless, crucian carp given ...

Random amplified polymorphic DNA (RAPD) analysis based on numerous polymorphic bands have been used to investigate genetic similarity and diversity among and within two cultured and wild populations represented by the species crucian carp (Carassius carassius). From RAPD analysis using five primers, a total of 442 polymorphic bands were obtained in the two populations and 273 were found to be specific to a wild population. 169 polymorphic bands were also produced in wild and cultured population. According to RAPD-based estimates, the average number of polymorphic bands in the wild population was approximately 1.5 times as diverse as that in cultured. The average number of polymorphic bands in each population was found to be different and was higher in the wild than in the cultured population. Comparison of banding patterns in the cultured and wild populations revealed substantial differences supporting a previous assessment that the populations may have been subjected to a long period of ...
In order to elucidate the importance of food-borne chemical contamination in fish, cytological and ultrastructural alterations in hepatocytes and enterocytes of common carp Cyprinus carpio L. exposed for 5 wk to 0.5 microgram endosulfan (6,7,8,9,10,1
Carbon dioxide (CO2) mixed into water is being explored as a possible management strategy to deter the upstream movements of invasive carps through navigation locks and other migratory pinch-points. This study used two-dimensional acoustic telemetry to assess the effectiveness of dissolved CO2 as a chemosensory deterrent to two carp species in a large U-shaped pond. Free-swimming movements of telemetered bighead carp (Hypophthalmichthys nobilis) and grass carp (Ctenopharyngodon idella) were documented 24 h before treatment and 24 h during treatments at 60, 121 and 213 mg/L CO2 (mean concentrations in pond water). Several behavioral endpoints were then quantified and compared to evaluate deterrence efficacy. In general, results showed that both carp species responded similarly to CO2 treatments. Carps consistently relocated into areas away from the injection site and made fewer attempts to re-enter CO2 treated areas. On average, CO2 treatments reduced mid-line crosses between untreated and treated sides

In this study, we developed 134 novel polymorphic polynucleotide-repeat microsatellite markers for silver carp (Hypophthalmichthys molitrix) and characterized 40 loci for polymorphism and genetic diversity in a test population. The number of alleles per locus ranged from 3 to 19 (mean 9.4), and the average observed and expected heterozygosities were 0.74-0.76, respectively. Thirty-five loci were highly informative (PIC > 0.5) in silver carp population. After Bonferroni adjustments, no pairs of loci showed evidence of significant linkage disequilibrium, and none of the loci significantly deviated from the Hardy-Weinberg equilibrium. All 134 silver carp microsatellite loci could be successfully amplified in bighead carp (Hypophthalmichthys nobilis) with 65 loci being polymorphic, indicating a high transferability of these microsatellites across species. This set of novel highly polymorphic polynucleotide-repeat microsatellites would be powerful tools for population and conservation genetics ...
The common carp, Cyprinus carpio, is a tetraploid fish species from the family Cyprinidae that arose about 20-50 Myr ago. The aim of the present work was attempting to understand the functional role of the duplicated common carp GH genes by studying their structure, evolution and expression. The introns of the second GH gene of common carp were sequenced for the first time and sequence comparisons of coding and non-coding regions of alleles of both GH genes were carried out. A phylogenetic analysis was done to examine the relationships of common carp GH genes with GH genes of the tetraploid goldfish and other diploid Cyprinids. In addition, phylogenetic analyses were done with other duplicated genes of common carp, some of which also important for growth. The relative rate test of Tajima (1993) showed a statistically significant increase in the evolution rate of the common carp GH I gene. In addition, some other duplicated gene pairs in common carp and goldfish with relaxation of functional ...

Adaptation of Common Carp (Cyprinus carpio L.) to Regular Swimming Exercise I. Muscle Phospholipid Fatty Acid Composition and Lipid Peroxide Status Abstract.
The common carp (Cyprinus carpio L.) is one of the major aquaculture species, contributing nearly 35% to the inland fish production in Karnataka, India. Stocks collected from Hungary (2), Indonesia and Vietnam were assessed alongside two local stocks in a series of culture performance trials with the objective of setting up a base population for developing a breeding programme. The present study deals with the genetic divergence and polymorphism in these six stocks using random-amplified polymorphic DNA (RAPD) markers. A total of 180 decamer random primers were screened for polymerase chain reaction (PCR) amplification (OPA 1-20, OPB1-20, OPC1-20, OPD1-20, OPE1-20, OPF1-20, OPG1-20, OPP1-20 and OPM1-20). Eight primers were selected for analysis of common carp genotypes (OPA-7, OPA-20, OPB-17, OPF-10, OP F-9, OPG-4, OPG-9 and OPP-16). Out of 492 bands recorded, 57.1% were polymorphic. Stepwise regression analysis was carried out to find best combination markers affecting body weight (P , 0.001). ...

Common carp (Cyprinus carpio) is one of the worlds most widely introduced and established freshwater fishes (Casal 2006). The species is considered to be one of the eight most invasive freshwater fishes (Lowe et al. 2000) and worldwide, it accounts for most of the records of successful establishments and adverse ecological effects (Casal 2006; Kulhanek et al. 2011). This invasive success suggests that feral C. carpio is equipped with a set of adaptable life history attributes that allow it to successfully colonise a wide range of habitats (Koehn 2004; Zambrano et al. 2006; Britton et al. 2007). Where feral C. carpio occurs in high densities, it is often perceived as an invasive pest species (Sivakumaran et al. 2003; Brown and Walker 2004; Koehn 2004) because it can have severe impacts on habitat heterogeneity and biodiversity by increasing water turbidity through its bottom feeding behaviour, increasing nutrient availability, decreasing benthic and macrophyte density and diversity, altering ...
The present study investigated the effects of condensed tannins (CT) on intestinal immune function in on-growing grass carp (Ctenopharyngodon idella). A total of 540 healthy grass carp were fed six diets containing different levels of CT (0, 10·00, 20·00, 30·00, 40·00 and 50·00 g/kg diet) for 70 d and then challenged with Aeromonas hydrophila for 14 d. The results showed that, compared with the control group, dietary CT (1) induced intestinal histopathological lesions and aggravated enteritis; (2) decreased lysozyme and acid phosphatase activities, complement 3 (C3), C4 and IgM contents and down-regulated the Hepcidin, liver-expressed antimicrobial peptide (LEAP)-2A, LEAP-2B, Mucin2 and β-defensin-1 mRNA levels in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI) (P , 0·05); (3) down-regulated the mRNA levels of anti-inflammatory cytokines transforming growth factor (TGF)-β1, TGF-β2 (not in MI and DI), IL-4/13A (not IL-4/13B), IL-10 and IL-11 partly correlated ...
Three embryonic class II myosin heavy chains (MYHs) were cloned from the common carp (Cyprinus carpio L.), MYHemb1,MYHemb2 and MYHemb3. MYH DNA clones were also isolated from the slow muscle of adult carp acclimated to 10°C (MYHS10)and 30°C (MYHS30). Phylogenetic analysis demonstrated that MYHemb1 and MYHemb2 belonged to the fast skeletal muscle MYH clade. By contrast, the sequence of MYHemb3 was similar to the adult slow muscle isoforms, MYHS10 and MYHS30. MYHemb1 and MYHemb2 transcripts were first detected by northern blot analysis in embryos 61 h post-fertilization (h.p.f.) at the heartbeat stage, with peak expression occurring in 1-month-old juveniles. MYHemb1 continued to be expressed at low levels in 7-month-old juveniles when MYHemb2 was not detectable. MYHemb3transcripts appeared at almost the same stage as MYHemb1transcripts did (61 h.p.f.), and these genes showed a similar pattern of expression. Whole mount in situ hybridization analysis revealed that the transcripts of MYHemb1 and ...
The Science Issue and Relevance: Triploidy is the condition in which three chromosome sets occur in somatic cells. Triploidization is the most practical, economical, and effective method for mass production of sterile fishes. Some examples include triploid oysters Crassostrea spp., Grass Carp Ctenopharyngodon idella, and Black Carp Mylopharyngodon piceus that are commercially cultured for consumption, weed and snail control, respectively. Additionally, triploid walleye Sander vitreus, crappie Pomoxis spp., striped bass Morone saxatilis, and salmonids are stocked for recreational fishing. Triploidization limits the potential for establishment of wild populations. However, treatments used to induce triploidy often do not achieve 100% triploids in a spawn.. Differentiating diploids from triploids at the earliest life stage possible allows for a more efficient use of resources including production time and rearing space. Thus, a reliable flow cytometric (FCM) method has been developed to ...

The present study investigated the effects of dietary vitamin A on immune function in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI) of young grass carp (Ctenopharyngodon idella). Fish were fed graded levels of dietary vitamin A for 10 weeks, and then a challenge test using an injection of Aeromonas hydrophila was conducted for 14 d. The results showed that, compared with the optimum vitamin A level, vitamin A deficiency significantly decreased fish growth performance, increased enteritis morbidity, decreased intestinal innate humoral immune response and aggravated intestinal inflammation. However, liver-expressed antimicrobial peptide 2A/B mRNA in the DI and IL-6, IL-17D, IL-10, transforming growth factor (TGF)-β1 and TGF-β2 mRNA in the PI were not affected by vitamin A levels. Meanwhile, vitamin A deficiency disturbed inflammatory cytokines in the PI, MI and DI, which might be partly linked to p38 mitogen-activated protein kinase (p38MAPK) signalling and NF-κB ...

The full-length cDNA of CiRIG-I was of 3198 bp and encoded a polypeptide of 947 amino acids with an estimated ...
Discussion. Metallic mixtures remaining in wastes may collect in various organs of animals or reason huge alteration in plant and fish biomass manufacture (Barman and Lal 1994). The toxicity data in this perusal showed that mercury chloride is toxic to silver carp (H. molitrix). In this report a series of hematological, biochemical and Immunological parameters were examined in silver carp after exposure to 10% and 50% LC50 doses of mercury chloride.. Hematotoxins alter qualitative and quantitative attributes of blood cells to produce toxic signs. when some of these other blood constituents are present or structural anomalies occurring in blood components meddle with normal functioning occur Hematotoxicity. Qualitative commutations in blood cell components can consequence in contamination (Landis and M 2004).. Although adequate in quantity, the quality of these small, less colored red blood cells impedes them from conveying the normal extent of oxygen (Landis and M 2004). Five examinations are ...

Cholinesterase (ChE) activity was used as a biomarker for assessing exposure of common carp (Cyprinus carpio) to organophosphate and carbamate insecticides from irrigated agricultural waters. Carp were collected from a lake (Royal Lake) that receives most of its water from irrigation return flows and from a reference lake (Billy Clapp Lake) outside of the irrigation system. Results indicated that the mean whole-brain ChE activity of carp from Royal Lake (3.47 μmol/min/g tissue) was 34.2% less than that of carp from Billy Clapp Lake (5.27 μmol/min/g tissue) (p = 0.003). The depressed ChE activity in brain tissue of Royal Lake carp was in response to ChE-inhibiting insecticides detected in water samples in the weeks prior to tissue sampling; the most frequently detected insecticides included chlorpyrifos, azinphos-methyl, carbaryl, and ethoprop. Neither sex nor size appears to be a covariable in the analysis; ChE activity was not correlated with fish length or weight...
Koi herpesvirus (KHV) caused significant morbidity and mortality in koi and common carp (Cyprinus carpio). Glycoprotein has been used for vaccine development as sub unit vaccine against many viruses. KHV ORF25 is one of koi herpesvirus genes which encode a glycoprotein. The objectives of this research are to clone gene KHV ORF25and express its protein. The common carp showing necrosis and white patches of gill which was collected from Magelang was used in this research. Primers were designed to amplify partial ORF25 based on KHV J strain. KHV ORF25 was successfully amplified and cloned in pET32a. Sequence analysis showed that this KHV ORF25 has 99% homology with the sequences of KHV genotype KHV-J, KHV-I, and KHV-U. This ORF was predicted has 3, 23, and 8 B-cell epitopes based on Emini scale, Karplus and Schulz scale, and ElliPro respectively. The KHV ORF25 recombinant protein has been successfully produced in Escherichia coli as an insoluble protein with approximately 45 kDa in size. The high ...
This project will enhance knowledge in the area of electromagnetic fields and health by clarifying some of the actual effects of low frequency electromagnetic fields (LF-EMF) on the innate immune system. The main goal of this project is to gain a basic understanding of possible LF-EMF effects at all levels of the organism (molecular, cellular and whole organism). Our model builds on existing in vitro models studying the formation of oxygen radicals in human monocytes, thus taking into account past research and established effects.The research questions in theis proposal address how LF-EMF modulate a) the in vitro response of macrophages, b) in vivo fish health and c) transcription of (immune-relevant) genes. The animal species of choice is fish, common carp (Cyprinus carpio L.), using an in vitro culture system of the fish equivalent of human bone marrow-derived macrophages. Carp macrophages will be exposed to LF-EMF treatments to measure macrophage activation. Microarray analysis will be used ...
Introduced - People took this fish species from its natural range and introduced it virtually worldwide. Garret Ellison, who covers the environment for MLive, spoke with IPR News about the proposed project, and whats at … The sterilization program has worked to some extent, but fertile fish are still being captured in locations where only sterile fish introduction is authorized.. In the case of all carp species, they intentionally were introduced to North America. Often, management or control techniques for prohibited species are not available. The structure on the Des Plaines River is a choke point between the Illinois River, which is infested with the invasive carp, and Lake Michigan. In North America, the term Asian carp typically refers to two species of invasive fish introduced from Asia: the bighead, or bigheaded carp (Hypopthalmichthys nobilis) and the silver carp (Hypopthalmichthys molitrix).These carp are native to China. Black carp are the largest of the four invasive carp ...
Background Aquaporins (Aqps) are integral membrane proteins that facilitate the transport of water and small solutes across cell membranes. Among vertebrate species, Aqps are highly conserved in both gene structure and amino acid sequence. These proteins are vital for maintaining water homeostasis in living organisms, especially for aquatic animals such as teleost fish. Studies on teleost Aqps are mainly limited to several model species with diploid genomes. Common carp, which has a tetraploidized genome, is one of the most common aquaculture species being adapted to a wide range of aquatic environments. The complete common carp genome has recently been released, providing us the possibility for gene evolution of aqp gene family after whole genome duplication. Results In this study, we identified a total of 37 aqp genes from common carp genome. Phylogenetic analysis revealed that most of aqps are highly conserved. Comparative analysis was performed across five typical vertebrate genomes. We found that

Recent research suggests the common carp (Cyprinus carpio) is often invasive in the North American Midwest due to its propensity to exploit shallow basins prone to winter hypoxia for reproduction. It has been shown that seasonally hypoxic basins often support extremely high abundances of young-of-the-year carp, but the fate of these carp is unknown. To determine whether these proposed nurseries serve as a source of recruits at a watershed scale, we used a population genetics approach to investigate carp recruitment in a system of interconnected lakes, ponds, and wetlands in central Minnesota. We collected carp tissue samples (n=939) from all basins throughout the watershed and from individuals moving between lakes and proposed nurseries. Microsatellite analysis revealed 2 genetically distinct strains of carp within the watershed.

A survey of DNase I in nine different carp tissues showed that the hepatopancreas has the highest levels of both DNase I enzyme activity and gene expression. Carp hepatopancreatic DNase I was purified 17,000-fold, with a yield of 29%, to electrophoretic homogeneity using three-step column chromatography. The purified enzyme activity was inhibited completely by 20 mM EDTA and a specific anti-carp DNase I antibody and slightly by G-actin. Histochemical analysis using this antibody revealed the strongest immunoreactivity in the cytoplasm of pancreatic tissue, but not in that of hepatic tissue in the carp hepatopancreas. A 995-bp cDNA encoding carp DNase I was constructed from total RNA from carp hepatopancreas. The mature carp DNase I protein comprises 260 amino acids, the same number as the human enzyme, however, the carp enzyme has an insertion of Ser59 and a deletion of Ala225 in comparison with the human enzyme. These alterations have no influence on the enzyme activity and stability. Three amino acid
Durante o processo de criação e comercialização de peixes ornamentais existem muitos fatores que podem causar estresse nos peixes, sendo o transporte um dos principais. O estresse pode prejudicar a saúde e comprometer a sobrevivência dos peixes, podendo causar prejuízos aos produtores. O uso de anestésicos durante os procedimentos de manejo e transporte, bem como o jejum antes do transporte vêm sendo utilizados a fim de minimizar as respostas de estresse dos peixes ornamentais. Dentre os produtos com potencial anestésico em peixes destacam-se os produtos naturais, como os óleos extraídos de plantas. No presente estudo avaliou-se a utilização do óleo de hortelã, extraído da planta Mentha piperita, como anestésico para juvenis de carpa ornamental, Cyprinus carpio. Para tanto, foram realizados dois experimentos. O primeiro experimento avaliou a eficácia e a segurança do óleo de hortelã como anestésico para C. carpio e o segundo experimento avaliou o efeito do óleo de ...
Paddlefish (Polyodontidae), sturgeon (Acipenseridae) and bigheaded carps (Cyprinidae: Hypophthalmichthys spp.) are taxa shared by the Yangtze and Mississippi River Basins. In the Yangtze, native paddlefish (Psephurus gladius) are functionally extinct, sturgeon are maintained through stocking, and bigheaded carps (H. nobilis and H. molitrix) declining. In Mississippi River, native paddlefish (Polyodon spathula) are secure, pallid sturgeon (Scaphirhynchus albus) endangered, shovelnose sturgeon (S. platorhynchus) threatened, and lake sturgeon (A. fulvescens) locally imperiled, although large robust populations of all these species exist in portions of their ranges; introduced bigheaded carps are invasive and abundant throughout their range. Paddlefish and sturgeon are habitat specialists having long periods of maturation (, 7 years) and infrequent reproduction (every 2-3 years). In areas lacking adequate spawning and rearing habitat populations are maintained principally by stocking ...

Pituitary melanotropes release alpha-melanocyte-stimulating hormone (alpha-MSH) and acetylated beta-endorphin (NAc beta-end) during stress responses. However, effects of stressors on plasma concentrations of these hormones are highly inconsistent among fish species. Here, we show that also within a species, the common carp (Cyprinus carpio), fish sometimes respond with elevated alpha-MSH and NAc beta-end plasma levels, and at other times not. The origin of this variable response was investigated by (1) studying the effects of corticotropin-releasing hormone (CRH) on alpha-MSH and NAc beta-end release in vitro, (2) establishing where in the second messenger pathway coupled to CRH receptors melanotrope responsiveness is determined, and (3) testing modulatory actions of other hypothalamic factors (here opioid beta-endorphin). Melanotropes were in a high or low responsive state to CRH in vitro, which was especially evident when tissue was tested from fish kept at higher ambient water temperatures, ...
Epidermal mucus (mucus) is increasingly applied to fish ecological studies based on stable isotope analysis (SIA) due to its non-invasive collection. However, knowledge on mucus SI turnover rates of individual fish remains limited, including uncertainty over how they are influenced by fish body sizes. Here, a diet switch experiment predicted mucus SI turnover rates (δ13C and δ15N) as a function of time using samples taken over 200 days from 10 individually tagged common carp Cyprinus carpio covering two size groups. Non-linear mixed effects models revealed rapid turnover of both δ13C and δ15N (T50: 2-5 days; T95: 9-22 days); δ15N turnover rates were slower for the larger cohort, while δ13C turnover rates were independent of body size. Within size groups, turnover rates were not expected to vary between individuals. These experimental results suggest that due to these fast turnover rates, epidermal mucus can provide insights into the diets of fish over very short timeframes, although for ...
We hypothesized that apple snails would change life-history traits in the presence of common carp to reduce or avoid predation risk. Carp of about 150 mm body length were released in small plots set in a rice field in southern Japan at 0, 0.2, or 0.6 carp/m2. Egg-mass size, proportion of hatched eggs, and duration of hatching of the snail were measured once or twice a week from July to September. Snails collected in traps were used to estimate both snail density by the Jolly-Seber mark-recapture method and distribution of shell lengths in each plot. The weight of the snail was regressed on a size-weight equation, and the snail biomass was determined by multiplying the estimated density and the regressed weight. The reproductive effort of the snails was calculated as the number of eggs divided by the biomass of adult females. The egg mass size and reproductive effort were significantly increased in the presence of carp. These increases were considered as life-history changes of apple snails in the
BOZA-ABARCA, J et al. Hormone-induced spawning of wild and captive-grown spotted rose snapper Lutjanus guttatus using carp pituitary suspension and human chorionic gonadotropin. Cienc. mar [online]. 2011, vol.37, n.2, pp.125-139. ISSN 0185-3880.. Hormone-induced spawning of the spotted rose snapper Lutjanus guttatus was studied using wild and cage-grown fish. Carp pituitary suspension (CPS) and human chorionic gonadotropin (hCG) were assessed. Wild females (0.7-2.1 kg body weight (BW), n = 18) were collected by hook and line in the Gulf of Nicoya, Costa Rica, to induce final maturation and ovulation in the laboratory. In the first experiment, five doses of CPS were evaluated and spawning was only observed at the higher doses (4.0 and 4.5 mg CPS kg-1 BW); the doses used were lower than for other species under similar conditions. In the second experiment, CPS and hCG protocols were compared using cage-grown broodstock (n = 30 females, 462-995 g; n = 60 males, 400-600 g); egg production was more ...
Koi Herpesvirus (KHV) affects both juvenile and adult common carp and koi, and is especially lethal to fry. The high mortalities caused by the disease have had a negative impact on the international koi trade. Different diagnostic techniques have been used to detect KHV, including: isolation of the virus in cell culture, electron microscopy, several PCR tests, ELISA and in situ hybridisation. All of these methods are time consuming, laborious and require specialised equipment. A rapid field diagnosis of KHV in common and koi carp was developed using loop-mediated isothermal amplification (LAMP). The LAMP reaction rapidly amplified nucleic acid with high specificity and efficiency under isothermal conditions using a simple water bath. Two methods of extracting DNA from host tissue were compared: extraction by boiling and by using a commercial extraction kit. A set of six primers - two inner primers, two outer primers and two loop primers - was designed from a KHV amplicon. The reaction conditions were
A neurophysiological detector (NPD) is a hybridization of olfactory system neurons of the fish crucian carp, Carassius carassius L., with a computerized electronic device connected to a high-performance liquid chromatograph (HPLC). This system makes it possible to measure neurophysiological activities in the olfactory system of C. carassius L. after exposure of this fish to alarm pheromones. The construction of the system was presented for the first time at the 3rd International Symposium on Separation in Bio Sciences SBS 2003 in I.

Since the Americans are not currently doing anything anywhere else in the Mississippi River watershed, these carp are continuing to spread to its farthest reaches upstream all the way to the edge of Great Lakes basin from New York, along the Chicago crest, all the way to Wisconsin.. Please let us not kid ourselves. The longer the Americans wait to hydrologically separate the two watersheds, the greater is the risk that those already in the Great Lakes will start finding mates and turn Americas Great Lakes into giant carp ponds the way they have them all over China. (Keep wondering, too, what is the American win-win in letting the Asian carp eventually turn the Great Lakes into giant fish farms for the oriental market?). Since they eat and mate all of the time no matter the season, they will spread quickly in the Great Lakes like the jellyfish in the oceans and sweep up everything. If Canadians really want to try to do something to stop them, write the American politicians. Contact your American ...

It is a stark reminder that the Asian carp infestation that has overwhelmed stretches of river in the Mississippi River basin and is now threatening the waters of the Great Lakes isnt going to go away anytime soon: The Illinois Department of Natural Resources has hired a Louisiana chef for a made-for-media event this week to demonstrate just how good these fish can be to eat. Its part of the Target Hunger Now campaign, a state-sponsored humanitarian effort to turn the jumbo jumping carp into healthy, ready-to-serve meals for the needy. The program also provides venison to the poor. It already has provided thousands of meals to needy children and families, but this is about more than feeding the poor. Illinois is in a protracted battle with its neighboring Great Lakes states over how to beat back the carp migrating up the Chicago Sanitary and Ship Canal, a man-made link between the carp-infested Mississippi basin and Lake Michigan. Neighboring states want Illinois to slam shut two navigation ...
The present study compared the effectiveness of the Carp pituitary gland extract (PGE) and the synthetic hormone Ovaprim on spawning success of the stinging catfish, Heteropneustes fossilis during induced breeding. The PGE hormone was administered at 6 mg/kg of body weight for females and 2 mg/kg of body weight for males. In contrast, Ovaprim was administered at 0.3 ml/kg body weight and 0.1 ml/kg of body weight for females and males, respectively. The spawning success was higher in the Ovaprim-induced individuals with better performance recorded at all stages of spawning including latency period, ovulation, fertilization, hatching and incubation period compared to the PGE-induced individuals. In the Ovaprim induced individuals, the latency period occurred within 10 hours while in PGinduced individuals, the latency was after 15 hours. Similarly, ovulation rate was 90% for Ovaprim injected fish but lower 78.7% for PGE injected fish. Higher rate of fertilization was observed in the eggs of Ovaprim ...

Case Western Reserve University and Cleveland Metroparks Zoo researchers have developed a field test that quickly determines whether Asian grass carp, a threat to the Great Lakes, are sterile or can reproduce. Ohio and neighboring states prohibit sale of fertile grass carp but they have been found in a river feeding into Lake Erie. Scientists worry that reproducing fish could destroy food supplies and habitat essential to native species in the Great Lakes.
All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and then reared for 60 days. The obtained results revealed that all growth indices were significantly (p | 0.05) improved by increasing in the EMFs intensity. 2 mT treatment indicated the highest final weight (43.95 ± 0.27 g), weight gain (6.83 ± 0.10 g), weight gain rate (20.94 ± 0.13 %), daily growth rate (0.38 ± 0.00 g day-1), specific growth rate (1.26 ± 0.01 % day-1) and the lowest food conversion ratio (p | 0.05). Survival rate had significantly (p | 0.05) increased in all exposed treatments compared to the control group. In conclusion, ELF-EMF can enhance the growth indices and survival rate of common

Promyelocytic leukemia zinc finger (Plzf), a transcriptional repressor, is involved in survival and maintenance of pluripotent stem cells including embryonic and spermatogonial stem cells in mammals. Its cDNA was characterized and expression in proliferating spermatogonial stem cells of rohu (Labeo rohita), a farmed carp, was documented. In teleost, the information on its promoter activity is lacking. Here, we have isolated, sequenced and performed the first characterization of regulatory elements for Plzf being expressed in proliferating spermatogonial stem cells of rohu. About 3.2 kb of 5′-flanking region, relative to ATG start codon, derived by genome walking was sequenced. The 5′-RACE (rapid amplification of cDNA ends) analysis not only mapped the transcriptional start site but also detected non-coding exons. Interestingly, computational analysis detected several putative regulatory elements including TATA-box positioned in the first intron. Luciferase reporter assay was performed for serially

Background. Carp represent 40% of the world aquaculture production of fish, crustaceans and mollusks.. In 2015, global culture carp production reached 28.8 million tones, with more than 20 million tonnes were produced in China (link). According to FAO projections, it is estimated that in order to maintain the current level of per capita consumption, global aquaculture production of carp will need to reach 80 million tonnes by 2050.. Induced spawning in carp fish has traditionally been carried out by a combination of Gonadotropin Releasing Hormone (GnRH) analog, and a non FDA approved dopamine receptor inhibitor, or alternatively by a calibrated carp pituitary extract (CCPE).. Our Innovation We developed ZAGIN2, a novel spawning agent which utilizes FDA approved materials and is used by intraperitoneal or intramuscular injections.. As such, it has an advantage over commercial spawning agents such as ZAGIN 1 (Drori et al. 1994), Ovaprim, Ovatide which include a non FDA approved component for ...

We isolated a high-purity carp glycophorin from carp erythrocyte membranes and prepared the oligosaccharide fraction from glycophorin by β-elimination [1]. The oligosaccharide fraction was separated into two components (P-1 and P-2) using a Glyco-Pak DEAE column. These O-linked oligosaccharides (P-1 and P-2) were composed of glucose, galactose, fucose, N-acetylgalactosamine and N-glycolylneuraminic acid (NeuGc). The P-1 and P-2 contained one and two NeuGc residues, respectively, and the P-1 exhibited bacteriostatic activity [1]. Using NMR and GC-MS, we determined that the structure of the bacteriostatic P-1 was NeuGcα2→6 (Fucα1→4) (Glcα1→3) Galβ1→4GalNAc-ol. This O-linked oligosaccharide was unique for a vertebrate with respect to the hexosamine and hexose linkages and its non-chain structure.
Three weeks from the start of the AL Division Series, Workman has emerged among manager John Farrells top options to safeguard late-inning leads. But with the Red Sox holding a two-run edge over the Tampa Bay Rays last night, the 25-year-old rookie faltered, allowing a run in the seventh inning and a game-tying solo homer to James Loney in the eighth.. But alls well that ends well for the Red Sox, and lately, absolutely everything is ending well.. Super sub Mike Carp blasted a first-pitch slider from reliever Roberto Hernandez for a pinch-hit grand slam in the 10th inning, and the Red Sox stunned the freefalling Rays, 7-3, lowering to 8 their magic number for clinching their first AL East title since 2007.. Get a run in, Carp said, recalling his modest goal after idling on the bench for nine innings. I knew Id get the job done off the bat. I knew Id put a good swing on it, and it was going to be deep enough to drive a run in. Then, when I saw it go over the fence, it was . . . ...
James Carpenter. Maybe it was the draft day Saban shock when he sat at Engrams table and Carpenter was selected. Maybe its because I think hes an out of shape fat bastard and I laugh when Carroll says game shape, like Carp even remembers what that means. He looked like he was sweating signing his contract on seahawks.com he was so fat. I dont know, maybe the fact the dude is always hurt and can never achieve game shape? Maybe its because he sucked as a right tackle, as Charles Barkley would say he was TURRIBLE! I also get the impression he doesnt want it. He reminds me of another SEC guy and former Seahawk...Chris Spencer. A guy who was great in college and had all the tools but was too stupid and lazy to utilize his talent.

In general grass carp are not specialised feeders and have been shown to consume over 170 different species of aquatic plants. Mitzner (1978) and Zonneveld and Van Zon (1985) concluded that little shift in the qualitative structure of plant species in a water body will be evident after stocking with grass carp, although the biomass of vegetation would decrease. The less preferred species with spiny or hard tissues are not consumed until later in the season after supplies of other plants have declined. Smaller fish prefer different species of plant compared to the larger sizes, hence, over a period of time, the control of plants in a water body will be fairly comprehensive.. The differences in food preferences seen by some authors are a result of the size of the fish used or the ambient temperature. Smaller fish with smaller mouths prefer softer tissues of the submerged vegetation, and the growing roots of water hyacinth. Thus it would be preferable to stock smaller grass carp with water hyacinth ...
Inhabitants are called Crucians /ˈkruːʒən/[9] (frequently written as Cruzans).. Due to St. Croixs history of immigration, there is much debate as to what constitutes a native Crucian. The consensus in Crucian society is that if one is bahn ya (born here in Crucian dialect) on St. Croix, they can claim to be Crucian, but not necessarily a native Crucian. Those considered to be the native Crucians (or by the more politically correct term: ancestral native Crucian) of St. Croix are persons who can trace their ancestry to the era prior to U.S. Virgin Islands acquisition of American citizenship in 1927. Ancestral native Crucians (approximately one-fourth to one-third of St. Croixs population) largely consist of the descendants of enslaved Africans brought to the island by Europeans during the 18th and 19th centuries, as well as the descendants of paid laborers recruited by the Danish from the British and Dutch West Indies after emancipation in 1848. As on other Caribbean islands, many ...
