Resumo: | Present study investigated the effects of different feeding schedules on certain variables of water quality and growth performance of Nile tilapia juveniles. Fifteen 25-L aquaria were used to hold the experimental fish population for six weeks. Five fingerlings (1.86 ± 0.13 g) were stocked in each aquarium (200 fish m-3; n = 5). The diet provided to fish and the feeding rates adopted were the same for all fish. The daily ration was divided in four meals (8, 11, 13 and 16h). In the positive control group (25/25/25/25), the daily ration was equally divided in the four meals; in the negative control group (40/30/20/10), the daily ration was unevenly divided in a progressively decreasing fashion (40, 30, 20 and 10%) throughout the day; in the experimental group (10/20/30/40), the daily ration was unevenly divided in a progressively increasing fashion (10, 20, 30 and 40%) throughout the day. The feed conversion ratio results were better for 10/20/30/40 than for the other groups. The 10/20/30/40 feeding schedule probably best combined the dietary allowance for fish with the increase in water temperature during the day.
