The utility model discloses a multi-layer snail reproduction frame is characterized in that, set up 3 reproduction frame of 5 layers, each layer is a disc shaped frame, frame includes frame bottom and side wall, column setting middle position of the edge and center point in the bottom of the frame, used to set up breeding frame the propagation of frame column, three, is an isosceles triangle set, keep the breeding stand stable, frame bottom and side walls are made of polyethylene mesh, polyethylene mesh 8 mesh 20 mesh; the utility model is used in the breeding frame, water bottom silt too much or too deep water area, set up multi layer snail breeding rack, the rack body is in the appropriate layer, each layer in the frame frame on the bottom evenly scattered snail snail in male and female, male and female on the bottom of the frame independent mating, reproduction, growth of young snails, the snails in the water habitat, breeding or shelf life, expand the snail breeding With the living space, improve the water snail yield per unit area, the utility model has the advantages of simple design, convenient use, good effect.
【技术实现步骤摘要】
一种多层螺蛳繁殖架
本技术涉及渔业生产领域,具体是一种多层螺蛳繁殖架。
技术介绍
螺蛳是青鱼、鲤鱼等多种鱼类的优质饲料,同时也是净化水质的优质水生动物,螺壳圆锥形,坚厚,壳高约3厘米,壳顶尖,螺层7层,缝合线深,体螺层略大;壳面黄褐色或深褐色,有明显的生长纹及较粗的螺棱,螺蛳为胎生的,卵在母体的育儿室中受精发育,待生长成幼体以后才排出体外,自然状态下螺蛳在水体底部僻静的地方繁殖,在水体较深或淤泥过厚的区域,螺蛳没有适合的繁殖场所,影响了螺蛳的繁育成活率。
技术实现思路
为克服上述缺陷,本技术设计了一种多层螺蛳繁殖架。本技术的技术方案是,一种多层螺蛳繁殖架,其特征是,繁殖架设置3-5层,每层为一个圆盘形的架体,架体包括架底和侧壁,在架底的边缘与中心点的中间位置设置立柱,用于架起繁殖架架体,繁殖架的立柱为三支,呈等腰三角形设置,保持繁殖架稳固,架底和侧壁均采用聚乙烯网片制作,聚乙烯网片网目8-20目。有益效果:使用本技术繁殖架,在水域底部淤泥过多或水体过深的区域,设置多层螺蛳繁殖架,使架体处于合适的水层,在每层架体的架底上均匀撒开雌雄螺蛳,雌雄螺蛳在架底上自主交配、繁殖, ...
