... ATG12, a core autophagy protein, forms a conjugate with ATG5 to promote the formation of autophagosome membrane, and plays an important role in antiviral immunity. However, little is known about the function of ATG12 in fish. Here, we cloned the open reading frame (ORF) of large yellow croaker (Larimichthys crocea) ATG12 (LcATG12), which is 354 nucleotides long and encodes a protein of 117 amino a ...

Abstract:
... A full sequence of TaHSP70 (heat shock protein 70 of Tanichthys albonubes) was amplified which was 2398bp, including an open reading frame (ORF) of 1392bp encoding a polypeptide of 643 amino acids with all three HSP70 family signatures and cytosolic motif of EEVD. Genomic DNA structure analysis revealed that the TaHSP70 gene contained one intron in 5′UTR. BLAST analysis revealed that the TaHSP70 g ...
... This study evaluates the toxic effects of the organophosphate pesticide (OP) dichlorvos to the endangered Iberian toothcarp (Aphanius iberus). To this end, the lethal toxicity of dichlorvos based on 96h-LC50 bioassays was determined in saline water (50g/L), and in vivo effects of dichlorvos on cholinesterase (ChE) activity were investigated in adult female and male specimens. The 96h-LC50 value de ...
... Studying species flocks (e.g. Darwin's finches, Caribbean anoline lizards, East African cichlid fishes) has proven to be highly successful in understanding the forces driving speciation. The only known, intact species flock of cyprinid fishes, the 15 Labeobarbus species in Lake Tana (Ethiopia), includes eight piscivorous species. Piscivory is a rare specialisation among the highly successful (>200 ...

Abstract:
... Information on the life‐history traits of threatened fishes can inform their conservation as they can indicate resilience to environmental change and vulnerability to extirpation and extinction. Garra ghorensis, a small (< 140 mm total length) riverine cyprinid fish, endemic to the southern Dead Sea area, is critically endangered through habitat loss and invasive species. There are, however, no da ...

Abstract:
... Age structure, growth and size at sexual maturity of smallmouth yellowfish, Labeobarbus aeneus (Burchell), were assessed in 2008–2009. Despite its angling and food importance, little has been published on many aspects of its ecology and biology, specifically its age structure in the Vaal River system. Of 193 L. aeneus collected by gillnetting, 96 were assessed for sexual maturity, and ages were es ...
... Tropical regions are expected to be some of the most affected by rising sea surface temperatures (SSTs) because seasonal temperature variations are minimal. As temperatures rise, less oxygen dissolves in water, but metabolic requirements of fish and thus, the demand for effective oxygen uptake, increase. Gill remodelling is an acclimation strategy well documented in freshwater cyprinids experienci ...
... The effectiveness of antifreeze proteins as cryoprotectants for cryopreservation of genital materials has been always controversial in the literature. In the present study, we evaluated the effect of antifreeze proteins in cryopreservation of sperm in four fish species (66.6% Acipenseridae, 11.1% Cyprinidae, and 22.2% Sparidae). PubMed, Scopus, Web of Science, and Google Scholar search engines wer ...

Abstract:
... Stock-density indices are standardized methods for analyzing length-frequency data that quantify the length structure of a fish population into length categories that are of interest to recreational anglers. We adapted North American relative stock density (RSD) and proportional stock density (PSD) indices to four Italian endemic or native cyprinid species by means of two methods. In accordance wi ...
... Parasites potentially have important roles in aquatic ecosystems, although relatively little is known about their contributions to the complexity of food web structure. In this study, stable carbon and nitrogen isotope analyses (δ¹³C and δ¹⁵N) were applied for fish host–parasite systems in a shallow swamp–lake ecosystem to assess the validity of stable isotope technics to reveal the parasite-media ...

Abstract:
... Pelagic broadcast spawning cyprinids are a mobile group of fishes commonly found within semi-arid areas of the Great Plains of North America. In several species, upstream movements of 50 to 200 km have been reported and associated with reproductive migration. Long distance migrations also are associated with finding food and refuge. Goals of this study were to detect synchronous movement of Prairi ...
... Large rivers are highly important systems that require close monitoring of the ecological consequences of factors like commercial and recreational exploitation, channel alterations, and climate change. The Long‐Term Survey and Assessment of Large River Fishes in Illinois (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using daytime, pulsed‐DC electrofishi ...

Abstract:
... Recently, the concurrent use of multiple taxonomic groups in stream bioassessment is becoming increasingly common because the responses of each group to anthropogenic stressors may be different. In this study, a multimetric index based on fish and macroinvertebrate assemblages for the Huntai River basin (MMIHT) was developed using a dataset covering 54 sampling sites in order to assess ecosystem h ...
... Engraulicypris sardella (Günter, 1868) is a cyprinid fish exploited in the waters of Lake Nyasa that has been found to be infested by Ligula intestinalis (Linnaeus, 1758). Although L. intestinalis has been the subject of a number of studies, there is no information on the effects of this parasite on E. sardella . This study was therefore aimed at assessing the prevalence and intensity of the paras ...
... Autophagy and apoptosis are two key cell fate determination pathways, which play vital roles in the interaction between viruses and host cells. Previous research had confirmed that one strain of fish rhabdoviruses, Siniperca chuatsi rhabdovirus (SCRV), could induce apoptosis and autophagy after infection. In the current study, we continued to analyze the interaction of autophagy and apoptosis in S ...
... Autophagy and apoptosis play important roles in the occurrence and development of diseases. Largemouth bass virus (LMBV) is a primary agent that causes infectious skin ulcerative syndrome in largemouth bass and threatens the aquaculture of the species. We investigated the relationship between LMBV and autophagy, as well as the effect of autophagy on apoptosis induced by LMBV. Results showed that L ...
... High-throughput sequencing of the 16S rRNA gene of microbial communities was used to investigate how biofloc technology (BFT) improved water quality and fish yield in freshwater pond aquaculture. Three treatments included conventional treatment (CT), biofloc treatment (BT) and biofloc systems augmented with floc-forming bacterium (Zoogloea resiniphila MMB) treatment (BZT). The feeding trial lasted ...

... A recently described typing system based on sequence variation in the virulence array protein (vapA) gene, encoding the A-layer surface protein array, allows unambiguous subtyping of Aeromonas salmonicida. In the present study, we compile A-layer typing results from a total of 675 A. salmonicida isolates, recovered over a 59-year period from 50 different fish species in 26 countries. Nine novel A- ...

... Removal of cyprinid fish is a widely used biomanipulation tool to transform turbid shallow eutrophic lakes in north temperate regions into a clear water state. We here evaluate the removal of cyprinids from streams as a supplement to lake fishing. Since cyprinids often aggregate in high densities in lake inlet/outlet streams during winter migration, removal of fish in this space-confined habitat m ...

Abstract:
... Degradation of warmwater streams in agricultural landscapes is a pervasive problem, and reports of restoration effectiveness based on monitoring data are rare. Described is the outcome of rehabilitation of two deeply incised, unstable sand-and-gravel-bed streams. Channel networks of both watersheds were treated using standard erosion control measures, and aquatic habitats within 1-km-long reaches ...
