This study was conducted to investigate the acute toxic effects of ciprofloxacin, norfloxacin and florfenicol, which are widely used antibacterial drugs, on loach. Through a well-planned experimental design, we systematically monitored the physiological and behavioral characteristics of loach under different drug concentrations and exposure time, and evaluated the toxic effects of these drugs. Under specific test conditions, i.e. water temperature is maintained at (10.0 ± 2.0)℃, and the pH value...

One of the major global sectors is aquaculture, which includes shrimp farming. In order to determine the differences in shrimp development, muscle, and nutritional components, this study examines the use of new and traditional technology. The results of the various experimental groups’ Penaeus vannamei weight gain rate, specific growth rate, survival rate, and feed coefficient showed that the ecobased materials may encourage shrimp growth. Each group’s shrimp muscle had an essential ami...

The study of the diet of Bagrus bajad (Bagridae) was carried out on 520 specimens from the south-west of Lake Albert from December 2019 to December 2020. The relative importance index of food was used to evaluate quantitative aspect of diet. Percentages of global vacuity and average intestinal coefficient were 23.40% and 1.35, respectively. Analysis of 418 food-containing stomachs revealed that this fish has an omnivorous diet predominated by piscivorous and insectivorous. Larvae and ju...

Rastrineobola argetea (fishmeal) was compared to roasted soybean meal as protein ingredients for brood stock African cat fish (Clarias gariepinus) in March 2019 on Geossy farm, Uganda. The fish were observed for growth and reproductive indices. Brood stocks of average weight 327 g were fed on different feeds for a month. Feed A contained soybeans as the sole main protein source. Feed B contained fishmeal as the sole protein source. Feed C was the control (usual farm feeds). Growth indices of B w...
