.— Growth and feed utilization of the tilapia hybrid Oreochromis mossainbicus × O. niloticus cultured at different salinities under controlled laboratory conditions were studied for 2 mo. Fish (2.32 g mean initial weight) were grown in 113‐L aquaria at salinities of 0.5, 17 and 32 ppt at a density of 20 fish per tank. Mean specific growth, food conversion, and food consumption were determined at each salinity. There was no significant difference ( P > 0.05) in growth among the treatments, although feed conversion and feed consumption were significantly improved (P ≤ 0.05) when fish were grown at 17 and 32 ppt.
