1991年我市在龙门水库进行了小体积高密度网箱养鱼技术研究。经过一年的试验,每立方米水体仅投资700元,产量最好达200kg,盈利792.50元,投入产出比为1∶2.2,取得显著的经济效益和社会效益。现将小体积网箱养鱼技术简述如下: 1 网箱的结构与设置 1.1 网箱的规格 1.1.1 箱体体积在不小于1m~3,不大于8m~3之间为宜。箱体小,利于增加网箱内外水体交换的量和次数,而且较小的网箱(最佳在1～4m~3)容易管理。在生产中一人可管理20～30只。
In 1991, the city conducted a small volume high-density cage fish farming technology in the Longmen Reservoir. After a year of testing, the investment per cubic meter of water only 700 yuan, the best yield of 200kg, profit 792.50 yuan, input-output ratio of 1: 2.2, achieved significant economic and social benefits. Now small-size cage fish farming technology is briefly described as follows: 1 cage structure and settings 1.1 cage specifications 1.1.1 box volume of not less than 1m ~ 3, not more than 8m ~ 3 is appropriate. Small box, which will help increase the exchange of water inside and outside the cage volume and frequency, and smaller cages (the best in 1 ~ 4m ~ 3) easy to manage. One person in production can manage 20 ~ 30.
