综合养鱼是以水体为中心,根据生态经济学原理,以渔为主,利用传统技术精华和现代技术成就,把渔、农、牧、工等紧密结合起来的生产体系,具有十分显著的经济、社会和生态效益。下面介绍几种综合养鱼的主要形式。1 种草养鱼。利用饲料地、池埂及其斜坡等种草养鱼。据笔者试验,主养草食性鱼类,占总放养量的60～65％,混养滤杂食性鱼类。每年10月至翌年5月份每667m~2鱼池配备黑麦草地面积130～170m~2,5～10月份配备苏丹草或杂交狼尾草地面积300～400m~2,水肥管理适当,可收割饲草8000kg左右,可净产草食性鱼类300kg,滤食性鱼类约100kg,加上杂食性鱼产量,每667m~2可产鱼达500～600kg。
Integrated fish farming is a water-based, based on the principles of ecological economics, the main fishing, the use of traditional technology and modern technological achievements, the fishing, farming, animal husbandry, industry and other closely integrated production system has a very significant economy Social and ecological benefits. Here are some of the main forms of integrated fish. 1 species of grass fish. Use of feed, ponds and their slopes and other grass fish. According to the author’s experiment, the main grass-fed fish, accounting for 60 to 65% of the total stocking, mixed fish filter omnivorous fish. Each year from October to May of the following year, the grassland area of 667m ~ 2 ponds is equipped with ryegrass area of 130 ~ 170m ~ 2,5 ~ October with Sudan grass or hybrid grassweed area of 300 ~ 400m ~ 2, appropriate water and fertilizer management, harvesting forage 8000kg or so, can produce nectarine fish 300kg, filter-feeding fish about 100kg, plus omnivorous fish production, every 667m ~ 2 can produce fish up to 500 ~ 600kg.
