Free fatty acid metabolism in the air-breathing African catfish (Clarias gariepinus) during asphyxia.
In several waterbreathing fish species, hypoxia induces a decrease in plasma free fatty acid (FFA) levels as opposed to an increase in air-breathing mammals. We hypothesised that this change is coupled to the mode of breathing. Therefore, we followed the metabolic response of cannulated air-breathing African catfish to an 8-h asphyxia period. The hematocrit and hemoglobin increased significantl...
متن کاملMyxozoan pathogens in cultured Malaysian fishes. II. Myxozoan infections of redtail catfish Hemibagrus nemurus in freshwater cage cultures.
Cage-cultured Asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840), a popular food fish in Southeast Asia, proved to be infected by 3 myxozoan species. All the 3 species belonged to the genus Henneguya: 2 were identified as H. mystusia Sarkar, 1985 and H. hemibagri Tchang et Ma, 1993, while the other was described as H. basifilamentalis sp. n. All plasmodia were found in the gills and ...
متن کاملResponses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
متن کاملHistopathological Effects of Glyphosate on Juvenile African Catfish (Clarias gariepinus)
Most aquatic herbicides have undergone some toxicity testing for effects on non-target aquatic organisms, little of this testing has been conducted on early life stages of Clarias gariepinus. African catfish C. gariepinus were exposed to acute concentrations of glyphosate for 96hrs. The lethal concentration (LC ) 5O value of glyphosate was 0.295 mg l for 96h of exposure. The mean mortality perc...
