Growth of black porgy,Sparus macrocephalus, was studied experimentally at four ration levels from starvation to satiation and four temperatures ranging from 14.8 to 26.8°C. At maximum rations, the specific growth rate (SGR) increased with temperature and was a negative linear function of body weight. The relationship between SGR and ration levels was a decelerating curve. Stepwise regression was used to develop the predictive models for the specific growth rates. Maintenance rations and optimum rations both increased with increased temperature. The relationship between maintenance, optimum rations and body weight was influenced by temperature. Conversion efficiencies increased with ration from zero at maintenance ration to a peak at the optimum ration, then declined with further increased ration.
