The objectives of the study was to determine the total lipid content, fatty acid composition and tocopherol content of muscle of eleven fresh water fishes belongs to Cichlidae, Anabantidae, Siluridae, Cyprinidae, Channidae families lived in reservoirs in Sri Lanka and to find high nutritious fresh water fish and the relationship of diet of fish with the feeding habits of fish. Muscle lipid cont...

the poor performance of fishery subsector is most clearly evidenced by low adoption of fishery production technologies by farmers. the purpose of this research was analyzing influence of socio-economic factors on the adoption of fish production technologies by community-based farmers in cross river state, nigeria. a multistage random sampling technique was used in selecting 60 community-based f...

Blood is collected from experimental animals for a wide range of scientific purposes including; hematology, clinical biochemistry parameters, immunology, studies in bacteriology, parasitology and investigations in reproductive performance and health. The number of methods employed to collect blood from fish include; the puncture of caudal vein, dorsal aorta or cardiac vessels and the severance ...

Periods of stress are often associated with disease outbreaks in cultured fish, and stress is often characterized by the secretion of cortisol. Although stress and cortisol secretion are highly correlated in fish, the role of cortisol in affecting channel catfish (Ictalurus punctatus) pathogen susceptibility is unclear. The effects of short-term stress and exogenous cortisol administration on c...

The antimicrobial activity of origanum oil (OG) was determined against Salmonella Typhimurium and E. coli O157:H7. The efficacy of catfish gelatin coating containing selected concentrations of OG (0.5%, 1.0%, and 2.0%, v/v) was also investigated in catfish flesh irradiated, inoculated with both bacteria, and stored at selected temperatures. The antimicrobial activity of catfish gelatin coating ...

The F1 hybrid between a channel catfish female (Ictalurus punctatus) × a blue catfish (I. furcatus) male outperforms both parental species in most environments. However, reproductive isolating mechanisms between the species made it difficult to mass produce the F1 hybrid for commercialization until recent improvements in hormone usage. This study was undertaken to mix the genomes of the 2 speci...

Few accounts describe predator-prey interactions between common bottlenose dolphins (Tursiops truncatus Montagu 1821) and marine catfish (Ariopsis felis Linnaeus 1766, Bagre marinus Mitchill 1815). Over the course of 50,167 sightings of bottlenose dolphin groups in Mississippi Sound and along the Florida coast of the Gulf of Mexico, severed catfish heads were found floating and exhibiting movem...
