摘要:
本文从分析水库综合养鱼生态系统的生态关系入手,阐述了水库综合养鱼的内容、意义、理论依据以及发展水库综合养鱼的自然条件和实践基础,并对综合养鱼系统的鱼产潜力进行了预测。预测结果表明,水库发展综合养鱼比传统的粗养方式其单位面积鱼产量可获得大幅度提高。

Abstract:
Integrated fish culture in reservoirs, which combines cultured fine feed-eating fishes in net-cage with stocked feed-fiJter fishes out of net-cage in a ratk,nal proportion, is introduced-In teg rated fish culture is based upon environmental capacity criteria so as to take centre in feeding net-cage fish culture, to explore avenues by rationally using fertilizer to fish stocking and to increase output and effect.Furthermore, it can promote nutrient transference and enhance the energy conversion efficiency.As a result,the aquatic ecological conditions of reservoirs can be improved,the nutrients of ecosystem be transferred into fish production through various channels, the economic and eco-social ben if its of the ecosystem be obtained optimally. To carry out intergrated fish culture in reservoirs, the natural conditions, practical fundamentals and theoretical basis are described.The structures of ecosystem and interrelations between them in integrated fish culture are further analysed.The capacity of feeding net-cage fish culture is calculated and the ratio of stocking feed-filter fishes out of net-cage also recommended.Furthermore, the potential fish productivity for integrated fish culture in reserviors is predicted as follows: the total output can reach up to 3015.0 kg/ha, 6.7 times as much as that of extensive culture, and 3.4 times as that of fertilizer-used fish culture. The suggested integrated fish culture in reservoirs can be regarded as a reform favorable for traditional production system of fish culture in China, and a new stage in the process of turning extensive stocking into ecological flshery.
