近年来,国内学者在大水面养殖方面作了大量的探索与研究,取得了良好实绩,但由于地区、水域的差异致使不少技术带有局限性、应用推广时又过分强调水产品产量的横向比较,造成了大水面开发利用水平在各地区发展的不均衡,综合利用水域资源,运用生态经济学原理来指导大面积水域开发、研究的报告又不多.鉴此,本试验以南京地区5000亩具不同类型代表性的河沟为开发对象,运用水产养殖学,资源学,生态学、经济学等基本原理,重点围
In recent years, domestic scholars have made a great deal of exploration and research on large-scale aquaculture and have achieved good results. However, due to the differences in regions and waters, many of the technologies have their own limitations. In the application and promotion of aquatic products, they over-emphasize the horizontal production of aquatic products Compared with the previous survey, the development and utilization level of large water surface area is not balanced in all regions, and the comprehensive utilization of water resources and the principle of ecological economics to guide large-scale water area development and research are few. Mu with a representative of different types of river ditches for the development of objects, the use of aquaculture, resources, ecology, economics and other basic principles, the focus of Wai
