【Abstract】 A series of experiments on survival rate and gonad development of wintering prawns, Penaeus chinensis, feeded with compound diets were carried out. The results showed that the survival rates of the prawns feeded with compound diet were 92. 50% and 83. 33%, separately, in the first and second experimental stages, while the rates of the control prawns feeded with nereis and clams were 84. 17% and 81. 67% , and there were no significant differences between the compound feeded prawns and the control. Further practical tests gave similar results that the final survival rates of the compound feeded prawns and the control were 73. 61 % and 73. 33% respectively, and that the rates of prawns which gonad had developed to stage IV were 68. 0% for the compound feeded group and 58. 0% for the control group. Thus, both laboratory and practical experiments indicated that the compound feed was an applicable diet to substitude traditional diet of nereis and clams to wintering prawns.更多还原
