在天然水域中网箱养鱼是我国近几年来发展起来的一种新兴的养鱼业。我国网箱养鱼的特点是:以养殖鲢、鳙鱼为主,不投饲料,完全利用天然饵料。1973—1979年,我们在武昌东湖不同湖区进行了网箱培育鱼种的实验和生产性试验,探讨了提高网箱养鱼种效率的几个技术问题和网箱鱼种生长与浮游生物的关系。本文着重探索网箱养鱼种中的几个生态—生理学问题。试验在室内外同时进行,网箱设置在东湖水果湖实验区。
In natural waters, cage fish farming is a new type of fish farming developed in recent years in our country. The characteristics of China’s cage fish is: to breeding silver carp, anchovy-based, do not vote feed, the full use of natural feed. In 1973-1979, we carried out experimental and productive experiments on cages cultured in different lakes of East Lake in Wuchang, and discussed some technical problems of improving the efficiency of cage fish breeding and the relationship between the growth of cages and plankton . This article focuses on several ecophysiological issues in fish cage species. The experiment was carried out at the same time indoor and outdoor, and the cage was set in the experimental area of Donghu Lake Fruit Lake.
