  Influence of salinity on hybrids descended from O. niloticus♀ and O. urolepis urolepis♂ was investigated for 63 days. A total of 120 fry of 0.29 ± 0.01g were stocked in 1m3 plastic tanks at a density of 10 fish/m3 per tank. The experiment involved three salinity treatments 15, 25 and 35 with fresh water (2 salinity units) as control. The hybrids were fed on a balanced diet of 40% crude protein at 5% body weight twice a day. Water quality parameters were measured once a week. However, results on SGR, average weight gain and survival rate were not significantly affected by salinity (p>0.05). FCR differed significantly among treatments (p<0.05). The 25 Practical Salinity Unit (PSU) showed better growth performance than other treatments. Surprisingly all treatments showed better growth than control. When examined at the end of.. View More»
