网箱养殖泥鳅,可以实行高密度集约化养殖,单产较高,又便于捕捞和防逃。但同时因养殖密度较大,泥鳅发病率较高,管理难度较大技术操作水平要求较高。网箱分为苗种培育网箱和成鳅养殖网箱。泥鳅苗种培育网箱,采用聚乙烯网布做成,面积一般为10—25平方米,成鳅饲养网箱;用3x3聚乙烯网片做成,网目为0.5—1厘米,面积50平方米左右。网箱设在湖、河边或池塘内,箱底着泥,箱内必须铺上 Cage culture loach, intensive intensive farming can be implemented, higher yield, but also easy to catch and prevent flight. But at the same time due to the breeding density is larger, the incidence of loach higher, more difficult to manage the technical operation of the higher level. Cages are divided into seedling cultivation cage and into loach breeding cage. Loach seed culture cage, made of polyethylene mesh, the area is generally 10-25 square meters, into loach cage; made with 3x3 polyethylene mesh, mesh 0.5-1 cm, an area of ​​50 square feet Meters or so. Cages located in the lake, river or pond, the bottom of the mud, the box must be covered
