网箱养鱼是一种高密度集约式的饲养方法,是目前养殖业的一项新工艺。但是如何利用网箱发展城郊养鱼,缩短生产周期,降低成本,提高单位面积产量,是目前网箱养鱼必须要探讨的问题。为此,去年在本所的大湖开展了一年两次网箱养殖莫桑比克罗非鱼的试验,获得了较好的产量。共投放五口网箱,136.8m~2,饲养 Cage fish farming is a high-density intensive farming method and is currently a new technology in aquaculture. However, how to use cages to develop suburban fish farming, shorten the production cycle, reduce costs and increase yield per unit area are the issues that must be explored in current cage fish culture. To this end, we conducted a trial of cage farming of tilapia in Mozambique twice a year in the Great Lakes of this year last year, achieving better yields. Put a total of five cages, 136.8m ~ 2, feeding
