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 کاملThe effect of different feeding rates and restriction on the growth performance of Clarias gariepinus
This study seeks to investigate the effect of restricted feeding regimes at different rate on growth performance of Clarias gariepinus using static and flow through system. Fingerlings were divided into six batches for each systems with the first and second batch fed at 5% body weight (BW) every day and every other day respectively, the third and fourth batch were fed 10% BW every day and every...
متن کاملComparison of dietary butyric acid supplementation effect on growth performance and body composition of Clarias gariepinus and Oreochromis niloticus fingerlings
This study was conducted using butyric acid as a growth enhancer in the diets of Clarias gariepinus and Oreochromis niloticus. C. gariepinus (42.39 g ±1.17) were fed diets containing varying inclusion levels of butyric acid (BA); 0 (CG1), 0.5 (CG2), 1.0 (CG3), 1.5 (CG4), 2.0 (CG5) g kg -1, where, CG1 is the control or reference diet. O. niloticus (25.50 g ± 0.50) were also fed diets containing ...
