摘要
连续3年(1989～1991)在总面积48.4亩的12口土池塘中放养鲤、鲢、鳙、草鱼苗(12～20万/亩),采用施肥培养天然饵料、人工投饲(豆浆)和二者结合3种方法饲养。结果表明,浮游动物规格适宜、营养全面、可得性强,用其培育上述几种鱼苗既经济简便,又可使成活率和生长速度提高15％以上。
Common carp ( Cyprinus carpio L. ), sivler carp ( Hypophthalmichthys molitrix ) , bighead carp ( Aristichthys nobilis ) and grass carp ( Ctenopharyngodon idella ) fry were stocked into twelve earthern test ponds totalled 3- 2 ha at the rate of 1. 8- 3. 0 million fish ha-1 and reared by zooplankton, artificial feed (soybean meal fluid) and the combination of natural food and artificial feed furing three consecutive rearing seasons (1989, 1990, 1991). It was found that survival rate and growth rate of the larvae feeding upon zoo-plankton (rotifers such as Branionus calycilorus and B. angularis and cladocerons such as Moina sp. and Daphnia carinata ) were more than 15% higher than those of the larvae fed on soybean meal fluid. This is due to the suitable size, nutritional components and high ava-ialbility for zooplankton. Compared with the conventional method of fish larva rearing, cultivation of fish larvae by zooplankton has good advantages of feasibility and low costs.
