Compensatory Growth In Carnivorous Fishes

In order to study top-down effect of high trophic level species on marine ecosystem and the ecophysiological efficiency of carnivorous fishes under starvation stress, japanese sea bass [Lateolabrax japonicus (C. & V.)] and bastard halibut [Paralichthys olivaceus (T. & S.)] experiments were carried out under the condition of different starvation stress. The main results were summarized as follows: 1. Japanese sea bass: During the period of 28 days, twenty fishes were divided to five groups at initial weight of 0.6 1-0.93g. fed with copepod of freshwater, had been acclimatized to the experimental starvation levels: 0(control), 4(group A), 8(group B), 12(group C), 16d(group D) and temperature in 19.5 ?.O扖, all groups fed from the end of starvation to the end of experiment. 1.1 The wet weight loss rate (LR~)of the starved individuals is positively proportional to days of their starvation (1), the model is:LR~=2.2l64t ?3.6634 (r20.9767, p
