| Research aimed at verifying the necessary feeding frequency for the best performance of Nile tilapia, Oreochromis niloticus (Perciformes, Cichlidae) fries during sex reversal period in green waters. Approximately 1,600 seven-day-old fries, measuring 9.03mm and weighting 9.77mg, in a distribution of 80 fries/hapa, were fed on diet containing 43% of CP and 60mg of methyltestosterone/kg of diet at frequencies of 2, 3, 4, 5 and 6 feedings/day, divided equally over the light period, for 28 days. Parameters of growth, survival, uniformity, feed conversion and total biomass produced were measured. Growth was significantly (p < 0.05) reduced at the frequency of 2 times per day. Regression models were used to measure the effects of feeding frequency on total... |
