三层挂网,由三层网片组成。中间一层是小网眼,两面是大网眼。大网目比中间的小网目大3、4倍,而小网目网片比大网目网片高得多。当鱼类冲撞网衣时,使内网从外网网眼突出,形成兜状,鱼类陷入网兜而被捕获。捕鱼效果比一般刺网好,各层鱼都能捕到。三层挂网捕鱼,操作简便,不受水库底质影响、库水深浅的限制,一年四季都可捕捞。
Three linked to the network, composed of three layers of mesh. The middle layer is a small mesh, two large mesh. Large mesh than the middle of the small mesh 3,4 times, while the small mesh mesh network mesh is much higher than the large. When the fish collided with nets, the inner net protrudes from the outer net and forms a pocket, where the fish catch in the net pocket. Fishing nets than the general good, all layers of fish can catch. Three layers of fishing net, easy to operate, not affected by the sediment quality, the depth of the reservoir water restrictions, fishing all year round.
