水库渔业的发展与水域环境的保护是相互对立统一的辩证关系.渔业养殖是综合利用供水水库水资源的重要内容.阐述了二龙山水库的渔业优势条件和可能造成水质污染不合理的渔业养殖方式.在坚持环境保护优先的前提下,提出了二龙山水库以放养鲢、鳙为主的生态渔业发展方向和健康养殖之路,从而更好地保护库内鲢、鳙生物总量的涵养与水体生态平衡.
Aquaculture is important for comprehensive utilization of reservoir water resources; however, reservoir fisheries development should be placed in the context of aquatic environment protection. The article analyzed the favorable conditions for aquaculture and the unreasonable aquaculture patterns which could possibly cause water pol- lution in the Erlongshan reservoir. Ecologically oriented fishery development and healthy aquaculture method were also proposed. While Hypophthalmichthys molitrix and Aristichthys nobilis could be served as the main culture spe- cies, the reservoir fisheries should be aimed at the protection of the stock of Hypophthalmichthys molitrix and Aristichthys nobilis and the balance of aquatic ecosystem in Erlongshan reservoir.
