growth performance of nile tilapia (oreochromis niloticus) fed with diets containing different levels of hydrolysable and condensed tannin
this study was undertaken to evaluate the effect of hydrolysable tannin (ht) and condensed tannin (ct) on growth performance and body composition of nile tilapia. hydrolysable tannin and ct were included into diets at four levels (0, 5, 15, and 25 g kg-1 diet). the diet with zero tannin level acted as control and the response of fish fed diets containing tannin was compared to that of the contr...
متن کاملEffect of Different Salinity Levels on Growth and Survival of Nile Tilapia (oreochromis Niloticus)
A three months study was conducted in cemented tanks (2.896ft×0.762ft×0.914ft) to investigate the effect of different salinity levels on growth performance and survival of Nile tilapia (Oreochromis niloticus). Four salinity levels i.e. 1600 ppm in Treatment 1 (TI), 2400 ppm in TII, 3200 ppm in TIII and 4000 ppm in TIV were maintained while in control (T0) the salinity level was 800 ppm. Each tr...
متن کاملGrowth curves of Nile tilapia (Oreochromis niloticus) strains cultivated at different temperatures
Growth of Red, GIFT and Supreme Nile tilapia strains were evaluated. Fish were cultivated in indoor recirculation systems in 0.5 m3 tanks with controlled temperatures of 22, 28 and 30°C. Random samples of 20 fish from each strain (10 fish tank) were weighed at day 7, 30, 60, 90 and 120. Exponential model (y=Ae) and Gompertz model (y = Aexp(-Be)) were fitted and the estimates parameters were obt...
متن کاملProcessing objects at different levels of specificity.
How objects are represented and processed in the brain is a central topic in cognitive neuroscience. Previous studies have shown that knowledge of objects is represented in a feature-based distributed neural system primarily involving occipital and temporal cortical regions. Research with nonhuman primates suggest that these features are structured in a hierarchical system with posterior neuron...
متن کاملEffect of Different Levels of Dietary Supplementation of Saccharomyces cerevisiae on Growth Performance, Feed Utilization and Body Biochemical Composition of Nile Tilapia (Oreochromis niloticus) Fingerlings
This study was conducted to evaluate the effect of different levels of dietary supplementation of Saccharomyces cerevisiae on growth performance, feed utilization and body biochemical composition of Oreochromis niloticus fingerlings. Four diets containing supplementation at levels of 0, 0.5, 1 and 2 g kg−1 were fed to fingerlings of Nile tilapia (5.01±0.21 g) in four replicate tanks twice ...
