This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...

Raji, A.R. and Norozi, E. 2010. Distribution of external taste buds in walking catfish (Clarias batrachus) and piranha (Serrasalmus nattereri). J. Appl. Anim. Res., 37: 49-52. To determine the distribution of external taste buds (TB), 3 specimen each of the two species of aquarium fishes: Walking catfish (Claris batrachus) and Piranha (Serrasalmus nattereri), were studied. In walking catfish TB...

For modeling the electric organ discharge of Malapterurus electricus catfish we have set up the electromechanical scheme of the catfish as an electric dipole the charges of which are linked by a spring of stiffness k. We call this particular system of charges an oscillating electric dipole. Taking into account the main forces applied to this dipole and applying the Newton’s second law of motion...

Injuries caused by fish are common in marine and freshwater environments. Catfish of the Ariidae and Pimelodidae families cause about 80% of those injuries. One of the complications of injuries caused by fish is the retention of fragments of the stinger in the wounds. Here we report five cases (of a total of 127 injuries caused by catfish in the Brazilian coast) in which the retained fragments ...

Columnaris disease is the second leading cause of mortality in pond raised catfish in the southeastern United States. It is second only to enteric septicemia of catfish (ESC) caused by the bacterium Edwardsiella ictaluri. Most species of fish are susceptible to columnaris following some type of environmental stress and when water temperatures are in the upper part of their preferred temperature...

A liquid chromatographic (LC) method for determining 14 sulfonamide (SA) (sulfanilamide, sulfadiazine (SDZ), sulfathiazole, sulfapyridine, sulfamerazine (SMR), sulfamethazine (SMZ), sulfamethizole, sulfamethoxypyridazine, sulfachloropyridazine (SCP), sulfamonomethoxine, sulfadoxine, sulfamethoxazole, sulfadimethoxine (SDM), and sulfaquinoxaline (SQX)) residues in edible catfish, shrimp and salm...

Catfish diets must provide enough energy, protein, vitamins and minerals in the proper proportions for fast, efficient growth and health maintenance. Choosing the right feed plays an important role in determining the productivity and profitability of aquaculture operations. But, producers aren’t the only people who are interested in diet quality. Certain characteristics of the diet influence th...

Abstract Catfishes (Ictaluridae) are among North America’s most important ichthyofauna for human consumption and recreation. As such, research on Blue Catfish Ictalurus furcatus , Channel I . punctatus Flathead Pylodictis olivaris has been abundant in historic contemporary literature. A common technique studying catfish involves marking or tagging fish to understand behavior, sampling efficienc...

Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

The catfish particle swarm optimization (CatfishPSO) algorithm is a novel swarm intelligence optimization technique. This algorithm was inspired by the interactive behavior of sardines and catfish. The observed catfish effect is applied to improve the performance of particle swarm optimization (PSO). In this paper, we propose fuzzy CatfishPSO (F-CatfishPSO), which uses fuzzy to dynamically chan...
