水库网拦库湾养鱼是指利用水库的库汊,用聚乙烯网片经安装工艺,把库汊与水库主体部份拦堑开,隔鱼不隔水,形成活水区进行养鱼。具有投资少、见效快、管理方便、易起水等优点,是开发库区水土资源,提高鱼产量,增加经济效益的一个重要途径。我县开发护林水库库湾40座,进行网拦库湾养鱼14000亩,每亩增加产量50公斤以上,经济效益显著。现将水库网拦库湾养鱼技术简介如下: 一、库湾的选择选择口小肚大,拦网距离短的库湾。要求库底平坦,障碍物少,库尾农田村庄多,周围植被丰富,水质肥沃。汛期无激流,漂浮物少,水深不超过15米,面积不限,对培育鱼种的库湾应在50亩以下为宜。拦网基脚可在消落区内安装,方便经济,如在水中安装也一样可靠。
Reservoir network barging bay Bay fish is the use of reservoir library 汊, with polyethylene mesh installation process, the library 汊 part of the main dam with the reservoir open, separated from the fish without water, the formation of living water fish. With less investment, quick, easy management, easy to water, etc., is the development of reservoir water and soil resources, improve fish production, increase economic efficiency is an important way. Our county developed 40 reservoirs of shelterbelt reservoirs and carried 14,000 mu of fish in the bay from the bay to increase the output of more than 50 kg per mu and markedly improved the economic benefits. Now the reservoir network barrier Bay fish culture technology briefings are as follows: First, the choice of reservoir bay mouth large belly, blocking the short bay. Requires flat base, fewer obstacles, library farmland and more villages, rich vegetation around, fertile water. No flood in flood season, less floating objects, water depth not exceeding 15 meters, an area not limited, to cultivate fish species of Bay should be less than 50 acres is appropriate. Block base foot can be installed in the zone, easy and economical, as installed in the water is also as reliable.
