The relationships of C max to the body weight (W) at each temperature were described by a power equation: lnC max = a + b lnW. Covariance analysis revealed significant interaction of the temperature and body weight. The relationship of adjusted C max to water temperature (T) was described by a quadratic equation: C max =-0.369 + 0.456T - 0.0117T 2. The optimal feeding temperature calculated from this equation was 19.5℃. The coefficients of the multiple regression estimation relating C max to body weight (W) and water temperature (T) were given in the Table 2.展开更多

Aquarium experiments were respectively carried out for certain periods. Analysis of the data obtained during the run of the three conversion artificial food chain show that consumption of 235. 2 kg fresh (148. 3 kg dry weight) Isochrysis gathana produced 1 kg fresh weight (1 kg dry weight) Sebastodes fuscescens. Concentration of 1 J energy by Sebastodes fuscescens requires Isochrysis galbana containing 11 0. 7 J energy. Since the alimentary canal of Actemia salina was not totally evacuated of food residues at the end of experiment, their measured body weight increment would be slightly higher than the actual value.展开更多
