Efecto de la realimentación tras un periodo de ayuno sobre el crecimiento en el sargo picudo Diplodus puntazzo (Cetti, 1777)

| Resumo: | Compensatory growth is rapid growth induced by hyperphagic behaviour after starvation. The present paper studies this phenomenon in sharpsnout seabream Diplodus puntazzo (Cetti, 1777). We used control groups (LC) feeding ad libitum and starvation-refeeding ad libitum groups (AR). AR growth was double that of LC after the refeeding period, and food intake was also higher. Although AR did not reach LC final weight, condition index K was achieved. These results suggest the need to test this hypothesis over longer starvation and refeeding periods which could lead to hyperphagic behavior. |
