Description

一种黄颡鱼受精卵孵化装置
技术领域
本实用新型属于水产养殖技术领域,具体涉及一种黄颡鱼受精卵孵化装置。
背景技术
黄颡鱼Pelteobagrus fulvidraco(Richardson),属鲇形目Siluriformes、鲿科Bagridae、黄颡鱼属Pelteobagrus,是一种小型淡水经济鱼类,在我国各大水系均有分布。喜栖息于缓流多水草的湖周浅水区和入湖河流中,是一种典型的广食、偏肉食性鱼类,幼鱼主要食浮游动物和水生昆虫的幼虫,成鱼以小鱼和无脊椎动物为食。黄颡鱼营养价值高,生长速度快,适应环境和抗病能力强,容易饲养,市场需求量大,作为新的淡水优良养殖品种正被广大渔民认可,市场前景广阔。
黄颡鱼受精卵为黄色、粘性,自然环境中,一般沉于巢底或粘附在巢壁的水草须根等物体上发育,且自然状态下雌雄黄颡鱼发育也不同步。目前市场上尚未有黄颡鱼受精卵孵化装置。
实用新型内容
本实用新型的目的就是提供一种结构简单、成本低廉,能重复利用,并能降低发育不同期水花苗沉底死亡率的黄颡鱼受精卵孵化装置。
本实用新型的一种黄颡鱼受精卵孵化装置,包括圆形上边框、圆形底边框、支撑架,其特征在于,圆形上边框与圆形底边框通过支撑架相连,底网安装在圆形底边框上,侧围网固定在圆形上边框、圆形底边框之间,底网采用60目圆形筛绢,侧围网采用60目长方形筛绢。
本实用新型的一种黄颡鱼受精卵孵化装置使用时,将装置通过支撑架立于孵化池中,充氧,然后将黄颡鱼受精卵均匀散布到框中孵化。其优点是,操作简单、易于清洗、成本低廉,可反复使用,同时能避免鱼苗沉底缺氧死亡,提高孵化率,并方便收集鱼苗。
附图说明
图1为本实用新型的结构示意图;
1、圆形上边框,2、侧围网,3、圆形底边框,4、底网,5、支撑架。
具体实施方式
一种黄颡鱼受精卵孵化装置,包括圆形上边框1、圆形底边框3、支撑架5,其特征在于,圆形上边框1与圆形底边框3通过支撑架5相连,底网4安装在圆形底边框3上,侧围网2固定在圆形上边框1、圆形底边框3之间,底网4采用60目圆形筛绢,侧围网2采用60目长方形筛绢,底网4直径为45-55cm,侧围网2 的宽*长为(10-15)cm *(125-188)cm。
