Abstract

本实用新型公开了一种能够提高捕捞量和存活率的鱼网,它主要由网纲、捕捉网组成,最突出的地方是捕捉网的网片至少为三层。在使用时,小于疏网网目的鱼不能穿过疏网,鱼就会被卡在疏网的网目上不能脱身;大于疏网网目的鱼可穿过疏网,鱼被密网的网目挡住,密网向外凸,鱼只能在这个如网袋的密网中活动不会被卡死。这种鱼网还适用在大江、大海中进行捕捞。

Description

三重活鲜网
技术领域
本实用新型涉及一种捕鱼用的渔网。
背景技术
目前的捕捞业主要是使用普通的单层网与流刺网,这类网由于只有一层,在捕鱼的时候对于网的每一个网目的大小很难把握,网目太大捉不到小鱼、小虾而且捉到的鱼还有可能卡死在网上,存活率低;网目太小又捉不到大鱼。
现在还有一种渔网,就是把渔网设置成半圆形,在半圆形的渔网中心位置设置一个诱饵网,整个渔网的上方用一条绳与一个浮球连接着。使用时可以用手握拉住绳而将渔网抛入水中,网里装设诱饵的诱饵网,可引诱渔群前来觅食,而当渔群游入捕捉网时,即受到捕捉网的缠绕捕捉而无法逃脱。此类渔网虽能捕到鲜活的鱼,但是捕捞量太少,而且只能在溪洲、浅滩及河流中适用。
发明目的
本实用新型克服了现在技术中的不足,提供了一种结构简单,易于制造,捕鱼效率高的渔网。
本实用新型是一种三重活鲜网,包括网纲、捕捉网,与网纲连接的捕捉网至少分为三层网片,网片的中间层设为密网,密网的两面又设为疏网。在网纲的其中一条上间隔地设有浮子,网纲的另一条上间隔地设有铅粒。
所述的网纲的大小、浮子的大小与位置、铅粒的重量与位置可进行调节来配合渔网工作。
本实用新型的有益效果是:(1)结构简单,只需至少三层的网片;(2)提高了捕捞的捕获量与捕捉活鲜率;(3)适用于深海、浅海、江河、湖泊的捕捞;(4)易于操作;(5)易于制造。
附图说明
下面结合附图和实施例对本实用进一步说明。
图1是三重活鲜网结构图:
图1中浮子1、疏网2、密网3、铅粒4、网纲5、网目6。
具体实施例
在图1中,与网纲(5)连接的捕捉网由三层网片组成,其中中间层为密网(3),两边为疏网(2)。捕捉网的一边的网纲(5)上设置有间隔的浮子(1),起到使整个网浮于水面上;另一边的网纲(2)设置有间隔的铅粒(4),使整个网垂直于水中保持展开的。所述的网纲(5)、浮子(1)、铅粒(4)的大小、位置都可以进行调节。
在使用时,只要网纲(5)展开,与其连接的捕捉网也跟着展开。当有鱼从正面过来,不能穿过疏网(2)中的网目(6)时,鱼就卡在疏网(2)的网目(6)上不能脱身;可穿过疏网(2)的网目(6)时,鱼则被密网(3)的网目(6)挡住,并在密网中不停地向前挣扎,密网(3)向外凸,鱼只能在这个如网袋的密网中活动不会被卡死。而疏网(2)中一边的网目(6)起到收紧网目(6)的作用和另一边网目(6)则起到辅助密网(3)阻止鱼向前冲的作用,那么鱼从网的背面过来话,同样有此效果。整个网看起来如同有许许多的“网袋”。

Claims (3)

1、一种三重活鲜网,包括网纲(5)、捕捉网,其特征是:与网纲(5)连接的捕捉网至少分为三层网片,其中间层设为密网(3),密网(3)的两面分别置有疏网(2)。
2、根据权利要求1所述的三重活鲜网,其特征在于,所述的网纲(5)的其中一条上间隔设有浮子(1)。
3、根据权利要求1所述的三重活鲜网,其特征在于,所述的网纲(5)的另一条上间隔设有铅粒(4)。
