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 (Rs=aWb). The model predicting resting metabolism was obtained as:Rs=0.0834W0.8763·e0.0319T. The feeding metabolism correlated linearly with ration level and food consumption. The predicting model of feeding metabolism is:RF=0.5631+0.0341·T−0.0013C·W·T+0.0010W·T+0.0219C·W−0.3335C.
