Biological invasions are a major threat to global biodiversity. Australia has experienced many invasive species, with the common carp (Cyprinus carpio L.) a prominent example. Cyprinid herpesvirus 3 (CyHV-3) has been proposed as a biological control (biocontrol) agent for invasive carp in Australia. Safety and efficacy are critical factors in assessing the suitability of biocontrol agents, and extensive host-specificity testing suggests that CyHV-3 is safe. Efficacy depends on the relationship between virus transmissibility and virulence...

The effects of a portable solar water quality control machine (PSWM) on water quality and sediment of aquaculture ponds were studied in bream aquaculture ponds in Shanghai, China. PSWM operation reduced the temperature and dissolved oxygen (DO) differences between upper and lower water levels. Concentrations of NH4(+)-N, NO2(-)-N, TN, TP, COD and TSS increased rapidly and reached maximums at 12 h. The density and biomass of phytoplankton and levels of chlorophyll a reached maximums after 40 h of PSWM operation...

Three representative species of Cyprinidae fishes (Aristichthys nobilis, Ctenopharyngodon idellus, and Cyprinus carpio), which are abundant in Chinese surface waters, were studied to determine their sensitivity to copper (Cu) in acute exposures. We first performed acute toxicity tests to determine the Cu LC50 value for each species in water with varying characteristics. The biotic ligand model (BLM) was then calibrated using the toxicity data for these species together with binding properties specific to Cu...

Conservation biology often requires the control of invasive species. One method is the development and use of biocides. Identifying new chemicals as part of the biocide registration approval process can require screening millions of compounds. Traditionally, screening new chemicals has been done in vivo using test organisms. Using in vitro (e.g., cell lines) and in silico (e.g., computer models) methods decrease test organism requirements and increase screening speed and efficiency. These methods, however, would be greatly improved by better understanding how individual fish species metabolize selected compounds...

Zinc oxide (ZnO) nanoparticles (NPs) have been dramatically used in industry, biology, and medicine. Despite their interesting physico-chemical properties for application in various industrial, medical, and consumer products, safe use of ZnO NPs are under challenges due to the inadequate information related to their toxicological endpoints. Proteomics was applied to evaluate the sub-lethal effects of dietary exposure to ZnO NPs on serum proteome profile of juvenile common carp, (Cyprinus carpio). Therefore, ZnO NPs solution (500mgkg(-1) of feed) was added to a commercial carp feed for six weeks...

In this investigation, we examined the influence of different DNA extraction protocols on results obtained for intestinal microbiota of Prussian carp. We showed that significant differences were observed in numbers of reads, OTU's, Shannon index and taxonomic composition between two different DNA extraction protocols for intestine of Prussian carp (Carassius gibelio), and differences were also evident between microbial communities in the intestinal mucosa and intestinal content. Statistical analyses of 25 published articles also revealed a significant relationship between methods of DNA extraction and bacterial diversity in fish intestine of freshwater species...

Silver barb (Puntius gonionotus) is considered a promising medium carp species for freshwater aquaculture in Asia. This study in silver barb was carried out to evaluate the effects of total or partial substitution of dietary fish oil (FO) with linseed oil (LO) on growth, nutrient utilization, whole-body composition, muscle and liver fatty acid composition. Fish (12.1±0.4g of initial body weight) were fed for 60days with five experimental iso-proteinous, iso-lipidic and iso-caloric diets in which FO (control diet) was replaced by 33...

Insulin-like growth factor binding-protein 5 (igfbp5), the most conserved member of the IGFBP family in vertebrates, plays a critical role in controlling cell survival, growth, differentiation, and apoptosis. Here, we characterized the expression patterns of igfbp5a and igfbp5b in grass carp (Ctenopharyngodon idella), which are retained in many fish species, likely from the teleost-specific whole-genome duplication. Both igfbp5a and igfbp5b encode 268- and 263-aa peptides, respectively, which share a sequence identity of 71%...

BACKGROUND: Articular manifestations are common in systemic lupus erythematosus (SLE) whereas erosive disease is not. Antibodies to cyclic citrullinated peptide (anti-CCP) are citrulline-dependent in rheumatoid arthritis (RA), whereas the opposite is suggested in SLE, as reactivity with cyclic arginine peptide (CAP) is typically present. Antibodies targeting carbamylated proteins (anti-CarP) may occur in anti-CCP/rheumatoid factor (RF)-negative cases long before clinical onset of RA. We analysed these antibody specificities in sera from European patients with SLE in relation to phenotypes, smoking habits and imaging data...

The aim of this study was to investigate the effects of dietary vitamin E deficiency on systematic pathological changes and oxidative stress in fish. A total of 320 healthy common carp (Cyprinus carpio) were randomized into four groups; the control group was fed a basal diet supplemented with 100 IUkg-1 of vitamin E, while the three experimental groups were fed the same basal diet with reduced vitamin E content (0, 25, or 50 IUkg-1). Findings showed that fish in the experimental groups mainly presented with sekoke disease, exophthalmia, leprnorthsis, and ascites...

BACKGROUND: The contribution of smoking to rheumatoid arthritis (RA) is hypothesized to be mediated through formation of anti-citrullinated protein antibodies (ACPA). In RA, however, autoantibodies such as ACPA, rheumatoid factor (RF), and anti-carbamylated protein antibodies (anti-CarP) often occur together, and it is thus unclear whether smoking is specifically associated with some autoantibodies rather than others. We therefore investigated whether smoking is only associated with ACPA or with the presence of multiple RA-related autoantibodies...

BACKGROUND: Domestication of Atlantic salmon for commercial aquaculture has resulted in farmed salmon displaying substantially higher growth rates than wild salmon under farming conditions. In contrast, growth differences between farmed and wild salmon are much smaller when compared in the wild. The mechanisms underlying this contrast between environments remain largely unknown. It is possible that farmed salmon have adapted to the high-energy pellets developed specifically for aquaculture, contributing to inflated growth differences when fed on this diet...

A disease outbreak was reported in adult koi, Cyprinus carpio koi from a fish farm in Kerala, India during June 2015. The clinical signs were observed only in recently introduced adult koi, and existing population of fish did not show any clinical signs or mortality. Microscopic examination of wet mounts from the gills of affected koi revealed minor infestation of Dactylogyrus sp. in a few koi. In bacteriological studies, only opportunistic bacteria were isolated from the gills of affected fish. The histopathological examination of the affected fish revealed necrotic changes in gills and importantly, virus particles were demonstrated in cytoplasm of gill epithelial cells in transmission electron microscopy...

The microbiota of unsalted and salted (dry-cured with 2% salt) bighead carp (Aristichthys nobilis) fillets during storage at 4 °C were identified by 16S rRNA gene analysis. Eleven genera were present in the initial microbiota of bighead carp fillets, where Acinetobacter, Aeromonas and Kocuria were the dominant bacteria. As storage time progressed, the microbial composition of both unsalted and salted fillets became less diverse. Additionally, differences in microbiota were observed between these two treatments...

This study investigated the effects of dietary vitamin E on growth, disease resistance and the immunity and structural integrity of head kidney, spleen and skin in grass carp (Ctenopharyngodon idella). The fish were fed six diets containing graded levels of vitamin E (0, 45, 90, 135, 180 and 225 mg/kg diet) for 10 weeks. Subsequently, a challenge test was conducted by injection of Aeromonas hydrophila. The results showed that compared with optimal vitamin E supplementation, vitamin E deficiency caused depressed growth, poor survival rates and increased skin lesion morbidity in grass carp...

This study explored the possible preventive effects of dietary phenylalanine (Phe) on antioxidant responses, apoptosis and tight junction protein transcription in the gills of young grass carp (Ctenopharyngodon idella). Fish were fed six different experimental diets containing graded levels of Phe (3.4-16.8 g kg(-1)) for 8 weeks. The results showed that Phe deficiency induced protein oxidation and lipid peroxidation by decreasing the glutathione content and the activities and mRNA levels of Cu/Zn superoxide dismutase (SOD1), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione-S-transferase (GST) in fish gill (P < 0...

Long chain acyl-CoA synthetase 1 (ACSL1), a key regulatory enzyme of fatty acid metabolism, catalyzes the conversion of long-chain fatty acids to acyl-coenzyme A. The full-length cDNAs of ACSL1a and ACSL1b were cloned from the liver of a grass carp. Both cDNAs contained a 2094bp open reading frame encoding 697 amino acids. Amino acid sequence alignment showed that ACSL1a shared 73.5% sequence identity with ACSL1b. Each of the two ACSL1s proteins had a transmembrane domain, a P-loop domain, and L-, A-, and G-motifs, which were relatively conserved in comparison to other vertebrates...

Haploid gynogenetic screens increase the efficiency of forward genetic screens and linkage analysis in fish. Typically, UV-irradiated zebrafish sperm is used to activate zebrafish oocytes for haploid screens. We describe the use of UV-irradiated common carp sperm to activate haploid gynogenetic zebrafish development. Carp × zebrafish hybrids are shown to have a characteristic set of features during embryonic development and exhibit functional development of several tissues (muscle, heart and nervous system)...

The present study was conducted to investigate the effects of parasite infection on haematological parameters of common carp, Cyprinus carpio. To this end, fish with same age were sampled from a warm water fish farm. After fish sampling, fish were transferred to lab for parasite study. Parasite incidence percent and density were calculated for two population carps. After parasite study, to investigate the haematological parameters, the blood sampling was carried out from two group fish i.e. infected (n = 20) and non-infected fish (n = 20)...
