Survival, condition factor, and the initial and final coefficients of weight variation had no significant effect among treatments. Feeding rate had a greater influence on performance than frequency. Water quality variables remained within adequate levels for this species. Every 15 days, weight and length of all fish were measured to adjust the amount of feed offered. The external control consisted of four meals a day offered to apparent satiety (F4S). ![]() The experimental design was a 3 × 3 factorial with three feeding frequencies (F2, F4, and F6: two, four, and six daily meals, respectively), three feeding rates (R1, R2.5, and R4: 1.0, 2.5, and 4.0%/day of fish biomass, respectively), and three replicates, totaling nine treatments (F2R1, F2R2.5, F2R4 F4R1, F4R2.5, F4R4 F6R1, F6R2.5, and F6R4). Juveniles with mean±SD weight of 2.55☐.48 g and total length of 6.81☐.48 cm were divided into groups of 20 fish and reared in 30 polyethylene tanks of 50 L for 60 days. The effects of feeding rate and feeding frequency on the growth of laboratory-reared common snook (Centropomus undecimalis) were evaluated.
