An experiment was carried out to in two steps (the first was hormonal treatments and the other the larvae grow up phase) to determine the best ontogenic periods for larvae of the Nile tilapia (Oreochromis niloticus) regarding the feminization hormonal treatments by immersion baths during 36 hours with a 2.0 mg solution of estradiol valerate17 (VE).L-1. One thousand and two hundred larvae of Nile tilapia, from the same reproduction bunch were used. Larvae were allotted to 24 0.5 L plastic […]
