Effects of body weight and water temperature on maximum food consumption of juvenileSebastodes fuscescens (Houttuyn)
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.
