Abstract

本实用新型的技术公开了多孔型水蛭养殖栅栏,其特征是,采用直径10—30厘米的PVC管若干条,根据水体深度,每条PVC管长1.5—3.5米,使PVC管插入水体时,管体上部露出水面10—50厘米,PVC管管壁开挖若干个孔径2—8厘米的圆形或椭圆形的孔洞,PVC管上端采用直径3—8厘米的木条穿过作为连接撑,PVC管下端制成尖状,插入水体底部,成为多孔型水蛭养殖栅栏;使用本实用新型多孔型水蛭养殖栅栏,水蛭、螺蛳沿PVC管从水体底部爬到水面附近,水蛭、螺蛳可以通过孔洞自由出入,在PVC管内外管壁附着,增大了水蛭生活空间,提高了单位面积水体水蛭养殖产量;本实用新型材料易得、制作简便、效果显著,有推广价值。

Description

多孔型水蛭养殖栅栏
技术领域
本实用新型涉及渔业领域,具体是多孔型水蛭养殖栅栏。
背景技术
水蛭是生活于水体环境的环节动物,平时喜附着于水草等水体中的物体上,以水生螺蛳为食物,螺蛳一般营底栖生活,水体中有可以附着的物体时,螺蛳也能够大量附着于靠近水面的物体上,在大面积养殖水蛭时,由于水体中水蛭栖息物体有限,水蛭螺蛳不能大量附着,限制了水蛭单位面积产量的提高。
发明内容
为克服上述缺陷,本实用新型设计了多孔型水蛭养殖栅栏。
本实用新型的技术方案是,多孔型水蛭养殖栅栏,其特征是,采用直径10—30厘米的PVC管若干条,根据水体深度,每条PVC管长1.5—3.5米,使PVC管插入水体时,管体上部露出水面10—50厘米,PVC管管壁开挖若干个孔径2—8厘米的圆形或椭圆形的孔洞,PVC管上端采用直径3—8厘米的木条穿过作为连接撑, PVC管下端制成尖状,插入水体底部,成为多孔型水蛭养殖栅栏。
有益效果:使用本实用新型多孔型水蛭养殖栅栏,水蛭、螺蛳沿PVC管从水体底部爬到水面附近,水蛭、螺蛳可以通过孔洞自由出入,在PVC管内外管壁附着,增大了水蛭生活空间,提高了单位面积水体水蛭养殖产量;本实用新型材料易得、制作简便、效果显著,有推广价值。
附图说明
图1为本实用新型结构图。
图中:1:PVC管,2:木条,3:孔洞。
具体实施方式
结合附图说明本实用新型,多孔型水蛭养殖栅栏,其特征是,采用直径10—30厘米的PVC管1若干条,根据水体深度,每条PVC管1长1.5—3.5米,使PVC管1插入水体时,管体上部露出水面10—50厘米,PVC管1管壁开挖若干个孔径2—8厘米的圆形或椭圆形的孔洞3,PVC管1上端采用直径3—8厘米的木条2穿过作为连接撑, PVC管1下端制成尖状,插入水体底部,成为多孔型水蛭养殖栅栏;使用本实用新型多孔型水蛭养殖栅栏,水蛭、螺蛳沿PVC管1从水体底部爬到水面附近,水蛭、螺蛳可以通过孔洞3自由出入,在PVC管1内外管壁附着,增大了水蛭生活空间,提高了单位面积水体水蛭养殖产量;本实用新型材料易得、制作简便、效果显著,有推广价值。
