Abstract
Feeding-growth experiments on black porgy,Sparus macrocephalus, were carried out at four ration levels from starvation to satiation and four temperatures ranging from 14.8° to 26.8°C. The energy budget was used to calculate the metabolism in black porgy. Resting metabolism correlated significantly with body weight in power function at 24.4°, 20.1° and 14.8°C (R s=aW b). The model predicting resting metabolism was obtained as:R s=0.0834W 0.8763·e 0.0319T. The feeding metabolism correlated linearly with ration level and food consumption. The predicting model of feeding metabolism is:R F=0.5631+0.0341·T−0.0013C·W·T+0.0010W·T+0.0219C·W−0.3335C.
Using ln(RL+1), lnW, lnT and their interaction terms as independent variables, the prediction model of total daily metabolism was obtained by stepwise regression as: lnR T=−1.7328+0.3936lnW+1.1882ln(RL+1)−0.2823ln(RL+1)lnT+0.1555lnWlnT.
