Abstract

本实用新型提出的是重叠多层刺渔网。在网纲下面连接有外网和内网,外网与内网网目尺寸为1:2.5之间。外网设置在内网的一侧或两侧,构成两层重叠刺渔网或三层重叠刺渔网。本实用新型能够捕捞大鱼和小鱼,而且不容易被损坏,通过水中拦截捕挂鱼。具有强度大,捕捞量大,不破坏渔业资源的特点。适宜作为海洋和陆地水域捕鱼的刺网应用。

Description

重叠多层刺渔网
技术领域
本实用新型提出的是渔业领域的渔网,具体地说是重叠多层刺渔网。
背景技术
现有用于捕鱼的渔网有多层网,但网孔大的网容易被大鱼冲破,造成渔网的坏损,而小孔网则难以扑捉大鱼,因此,现有的渔网难以同时捕捞大鱼和小鱼,所以存在捕捞率低的缺陷。
另外当小孔网足够小时,成为绝户网,能够扑捉全部海洋生物,不利于保护海洋渔业资源。
发明内容
为了实现科学打渔,本实用新型提供了重叠多层刺渔网。该刺渔网通过外网和内网网目的设置与网目的匹配,解决有目的捕捞鱼的技术问题。
本实用新型解决技术问题所采用的方案是:
在网纲下面连接有外网和内网,外网与内网网目尺寸为1:2.5之间。
外网设置在内网的一侧或两侧,构成两层重叠刺渔网或三层重叠刺渔网。
积极效果,本实用新型能够捕捞大鱼和小鱼,而且不容易被损坏,通过水中拦截捕挂鱼。具有强度大,捕捞量大,不破坏渔业资源的特点。适宜作为海洋和陆地水域捕鱼的刺网应用。
附图说明
图1为本实用新型刺渔网结构示意图
图中,1.网纲,2.内网,3.外网。
具体实施方式
据图1所示,在网纲1下面连接有外网2和内网3,外网与内网网目尺寸为1:2.5之间。
外网设置在内网的一侧或两侧,构成两层重叠刺渔网或三层重叠刺渔网。
本实用新型的特点
1、重叠多层刺渔网,通过渔网的重叠,增加了渔网的强度,防止大鱼破坏渔网。
2、大网孔能够捕捞大鱼,而小孔网能够捕捞比较大鱼小的鱼,因此捕捞产量高。
3、由于外网和内网网目的限定,使渔网能够捕捞需要捕捞的鱼类,不破坏其它水生生物,有利于保护水生生物和小鱼,保护水生资源。
