The complete mitochondrial genome of the Southern catfish (Silurus meridionalis) and the Chinese catfish (S. asotus), was determined using the long and accurate polymerase chain reaction (LA-PCR) method. The mitochondrial DNA nucleotide sequences of S. meridionalis and S. asotus were compared with those of 47 other catfish species in the same order. The total length of mitochondrial DNA for S. ...

Yellow catfish (Pelteobagrus fulvidraco) is one of the most important freshwater aquaculture species in China. However, its small size and lower meat yield limit its edible value. Myostatin (MSTN) is a negative regulator of mammalian muscle growth. But, the function of Mstn in fish remains elusive. To explore roles of mstn gene in fish growth and create a strain of yellow catfish with high amou...

Evidence indicates that lateral-line fibers, other than those mediating the "spontaneous" activity of the lateral-line receptors, are brought into play in response to pressure stimuli in catfish and in trout. The distribution and mode of stimulation of mechanoreceptors along the lateral-lines of trout and catfish are discussed in relation to the natural activities of these forms.

Survivorship to ESC (enteric septicemia of catfish) varies among and within strains of commercially raised catfish, however the immunological basis for differences in susceptibility is not well-understood. We assessed the effect of pathogen challenge with Edwardsiella ictaluri on five genetic groups of catfish by measuring both phenotypic response (mortality, pathogen levels, specific growth ra...

Edwardsiella tarda is a Gram-negative facultative anaerobe causing disease in animals and humans. Here, we announce the complete genome sequence of the channel catfish isolate E. tarda strain C07-87, which was isolated from an outbreak of gastrointestinal septicemia on a commercial catfish farm.

Since 2009, a clonal group of virulent Aeromonas hydrophila strains has been causing severe disease in the catfish aquaculture industry in the southeastern United States. Here, we report draft genomes of four A. hydrophila isolates from catfish aquaculture that represent this clonal group.

diet of adult pikeperch sander lucioperca, eurasian perch perca fluviatilis, northern pike esox lucius and european catfish silurus glanis as top predators in aquatic ecosystems in serbia was investigated during 2011, in order to understand their relationship to their prey and to investigate their food consumption, feeding and assimilation rate, cannibalism, and habitat segregation. northern pi...

A red-tailed catfish (Phractocephalus hemioliopterus) referred to Aquatic Animal Health Department, Faculty of Veterinary Medicine, University of Tehran for showing lethargy, bottom sitting, extension of abdomen and severe abdominal injuries. Its abdomen was swollen and the bulk of the foreign bodies were easily palpated. The heaviness of foreign bodies had made swimming and buoyancy difficult ...

a study was carried out to evaluate the probiotic activity of bacillus subtilis g1 isolated from fermented pickles in growth performance and disease resistance of hemibagrus nemurus fingerlings at universiti putra malaysia. the probiotic was mixed in feed at doses of 0 (c, control), 3 x 109 (t1) 3 x 107 (t2) and 3 x 105 (t3) cfu g-1 and fed to the catfish fingerlings for nine weeks. results sho...

A time-resolved fluoroimmunoassay (TR-FIA) was established and validated that allows for the determination of plasma concentrations of insulin-like growth factor I (IGF-I) in three domestically cultured fishes: channel catfish (Ictalurus punctatus), hybrid striped bass (Morone chrysopsxM. saxatilis), and rainbow trout (Oncorhynchus mykiss). Sensitivity of the assay was 0.20 ng/ml. Intra- and in...
