| Resumo: | A preliminary evaluation of the growth and yield results in sub-adults of Lutjanus peru Pacific huachinango grown in marine floating cages, measuring fish length, weight, feed conversion, and survival rate during a 120 day fattening test in Playa Punta el Caballo, Nayarit State, Mexico. Nine floating cages (12.5 m3 capacity) were used as experimental units. The fish were placed in triplicate cages of 30, 50 and 70 fish / m3 (1.9, 3.3, and 4.4 kg / m3, respectively), using more than 5,600 wild subadults (mean initial weight ± SD = 63.9 ± 1.4 g) as initial supply. The fish were fed twice daily with commercial submergible pellet, and a weekly record of the dissolved oxygen, temperature, pH, turbidity, and ammoniacal nitrogen of each cage was carried out. After 120 days, the average individual weight at harvest was inversely proportional to the population density. |
