长江口区江苏、浙江、上海二省一市的沿海及沿江水域是我国鳗苗重要出口地之一。七十年代初期,在上海市主要河口性鱼类苗种资源的调查一文中曾提及部分闸口鳗苗情况。1987年,又详细报道了长江口北支崇明岛北岸闸口鳗苗生产量等问题。1987年在进行上海市污水集中排放对长江口生态环境影响的课题任务时,作者在长江南支、北支和杭州湾北岸带等水域,就有关鳗苗分布、生态和捕捞生产利用等进行了较全面的调查,探讨了资源变动因子和开发利用问题。
The Yangtze River Estuary Jiangsu, Zhejiang and Shanghai provinces and cities along the coast and along the Yangtze River is one of the important eel export. In the early 1970s, part of the gate eel was mentioned in a survey of the resources of major estuarine fish species in Shanghai. In 1987, it also reported in detail the production of eel seedlings at the north bank of Chongming Island in the north branch of the Yangtze River estuary. In 1987, when carrying out the task of concentrating sewage in Shanghai on the ecological environment of the Yangtze Estuary, the authors conducted a survey on the distribution of eel fry, ecology and utilization of fishing production in areas such as the South Branch of the Yangtze River, the North Branch of the Yangtze River and the northern coast of Hangzhou Bay A more comprehensive survey explores the resource change factors and development and utilization issues.
