Effect of probiotic Bacillus spp.-supplemented feed on the growth, length-weight relationship, and condition factor of Nile tilapia (Oreochromis niloticus)

Length-Weight Relationships, Condition Factor and Sex-Ratio of Nile Tilapia, Oreochromis niloticus in Wadi Hanifah, Riyadh, Saudi Arabia

The studies on length-weight relationships (LWR), condition factors (K) and sex-ratio of Nile tilapia, Oreochromis niloticus in Wadi Hanifah, Riyadh, Saudi Arabia was conducted from September 2011 to August 2012. A total of 575 specimens were collected from different sample stations using different types of net and by angling. The fishes were ranged from 76-273 mm, 69-261 mm and 69-273 mm in le...

Effect 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 ...

Effect of Dietary α-Cellulose Levels on the Growth Parameters of Nile Tilapia Oreochromis niloticus Fingerlings

Three purified diets were formulated using fish meal, soya bean, wheat flour, palm oil, minerals and maltose. The carbohydrate in the diets was increased from 5 to 15% by changing the cellulose content to study the effect of dietary carbohydrate level on the growth parameters of Nile tilapia Oreochromis niloticus. The protein and the lipid contents were kept constant in all the diets. The resul...
