— American White Pelicans ( Pelecanus erythrorhynchos ) are reported to consume large quantities of commercial catfish in Alabama, Arkansas, Louisiana and Mississippi, negatively impacting aquaculture production. If pelicans consume a single item diet, such as catfish, nutritional deficiencies may result. Therefore, effects of monoand multi-species diets were examined to determine nutritional i...
Two experiments were conducted in 200-m earthen ponds at Asian Institute of Technology, Thailand, for 87 days to test the feasibility of an integrated pen-cum-pond system, which utilizes wastes from intensive culture of hybrid catfish (Clarias macrocephalus C. gariepinus) as nutrients for semi-intensive culture of Nile tilapia (Oreochromis niloticus). This integrated pen-cum-pond system enhance...
PETRINEC, Z., S. NEJEDLI, S. KUŽIR, A. OPAČAK: Mucosubstances of the digestive tract mucosa in northern pike (Esox lucius L.) and european catfish (Silurus glanis L.). Vet. arhiv 75, 317-327, 2005. ABSTRACT The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described. The digestive tract of pike and catfish is short, in ac...
Catfish represent 12% of teleost or 6.3% of all vertebrate species, and are of enormous economic value. Here we report a high-quality reference genome sequence of channel catfish (Ictalurus punctatus), the major aquaculture species in the US. The reference genome sequence was validated by genetic mapping of 54,000 SNPs, and annotated with 26,661 predicted protein-coding genes. Through comparati...
, 5000 six-page surveys (Appendix 1) were sent to a stratified-random sample of Nebraska anglers drawn from the 2001 Licensed Anglers database. The database included all anglers who purchased a license in 2001 as well as all lifetime fishing permit holders who purchased their license before or during 2001. The database did not include those possessing a free permit, such as veteran's or senior ...
The carbamate pesticide, aldicarb, demonstrates significant acute toxicity in mammals, birds, and fish through the inhibition of acetylcholinesterase (AChE), and may present high potential for exposure of aquatic organisms during periods of runoff. Toxicity studies have shown that channel catfish are less sensitive to the acute toxic effects of aldicarb than are rainbow trout or bluegill. An ea...
Vibrio anguillarum was isolated from several organs of some aquarium catfish in a fish population with high mortality. Macroscopic examination of the affected catfish revealed ascites in the abdomen, site-petechiae, and dorsal erection. Although there are some variations in phenotypic characterization among different isolates of Vibrio anguillarum, the majority show a common biochemical profile...
An experiment was conducted to test using effluents from intensive hybrid catfish (Clarias macrocephalus × C. gariepinus) ponds as nutrient inputs for Nile tilapia (Oreochromis niloticus) culture, which would reduce effluent effects from catfish culture, gain extra fish production at low cost, and possibly make aquaculture more profitable to farmers. Three treatments were done with three replic...
Channel catfish (Ictalurus punctatus) with a golden pigment and black spots were discovered during harvest of a University of Arkansas at Pine Bluff (UAPB) experimental channel catfish production pond. Golden catfish were mixed with catfish of normal pigmentation and of similar sizes. Following the observation that differences existed in algal-off flavor, three golden and three normal pigmented...
Edwardsiella ictaluri (E. ictaluri), a Gram-negative, intracellular, facultative bacterium, is the causative agent of enteric septicemia of catfish (ESC), which is one of the most significant diseases of farmed channel catfish. Macrophages have a critical role in major defense mechanisms against bacterial infections by migrating to the site of infection, engulfing and killing pathogens, and pri...
