Abstract

Maximum rate of food consumption (Cmax) was determined for juvenileSebastodes fuscescens (Houttuyn) at water temperature of 10, 15, 20 and 25°C. The relationships ofCmax to the body weight (W) at each temperature were described by a power equation: InCmax=a+b InW. Covariance analysis revealed significant interaction of the temperature and body weight. The relationship of adjustedCmax to water temperature (T) was described by a quadratic equation:Cmax=−0.369+0.456T−0.0117T2. The optimal feeding temperature calculated from this equation was 19.5 °C. The coefficients of the multiple regression estimation relatingCmax to body weight (W) and water temperature (T) were given in the Table 2.
