Abstract: | The optimum ration in relation to water temperature has been determined for juvenile sea bass (Dicentrarchus labrax). Fish were reared at 15 and 20°C. The spontaneous food intake was positively related to temperature. Four daily rations were tested at both temperatures. The optimum rations were 1.7% at 20°C and 1.2% at 15°C for fish weighing 20–30 g. The influence of temperature on growth rate, body composition and food conversion was studied. Increasing the temperature improved growth rate and gross conversion efficiency but not gross protein efficiency. The results are discussed in terms of energy utilization. |
