The invention discloses a shelter device for cultivating crab species of mud crab. The device includes a aquaculture box and a shelter in a culture box; the aquaculture box is a quadrangle with a top opening; the shelter is a quadrangle with a side opening, and a shelter is fixed to a corner of the aquaculture box, three of which are tightly attached to the inner wall and the bottom adjacent to the aquaculture box, and one side which is not connected to the breeding box is set as an opening. End. The four walls of the culture box are provided with circular holes, and the circular holes are covered with stainless steel netting. The aquaculture box and shelter are made of non-toxic corrosion-resistant hard material such as PVC. Compared with the traditional cultivation pool, the shelter device is placed in the cultivation pool, and the sand is placed in the shelter device. At the same time, the green crab is also placed in the shelter device to feed outside the shelter device. The food residue and excreta of Scylla serrata are produced outside the shelter device. After using the invention, the water exchange and rinsing of the pond can be conveniently carried out, and the workload is greatly reduced.
【技术实现步骤摘要】
一种用于拟穴青蟹种蟹培育的遮蔽物装置
本专利技术涉及一种用于拟穴青蟹种蟹培育的遮蔽物装置,属于海洋生物养殖领域。
技术介绍
拟穴青蟹是温暖海区沿岸生活的蟹类,目前的人工繁育方法为先从自然海区或者养殖池塘中挑选性腺发育较好的膏蟹作为种蟹,不同种蟹的卵巢发育饱满程度差异较大,需要对种蟹进行营养强化促熟培育为抱卵蟹,这一阶段根据种蟹性腺发育状况及水温等环境因素不同需要数天到数周不等。在种蟹培育成为抱卵蟹的过程中,由于青蟹具有强烈的领地意识、凶猛好斗、穴居习性,同时种蟹培育池空间有限,种蟹容易因打斗造成伤残进而引发感染,使种蟹培育效率低下。目前的养殖方式为在种蟹培育池中以培育池相邻两边为边,用砖围成一个内池,培育池中内池以外的部分则形成一个L形的区域。在内池中铺设沙子,并在沙子上放置砖块、碎瓦片、竹筒等作为种蟹遮蔽物,内池外的L形区域作为饵料投喂区。在种蟹摄食过程中,会将部分食物残渣及排泄物带入内池,由于内池是在沙面上放置有众多遮蔽物,导致对内池的清理造成不便。其次,在种蟹培育过程中需要每天清理残饵粪便同时清洗种蟹培育池,由于内池砌砖围沙的结构设置,冲洗时会带出部分沙子,导致堵塞培育池的出水口。
技术实现思路
本专利技术所要解决的技术问题在于提供一种用于拟穴青蟹种蟹培育的遮蔽物装置,改变了种蟹培育过程中遮蔽物的设置方式,便于培育池的换水清洗及防止换水清洗时堵塞出水口。为了解决上述技术问题采用了以下技术方案:一种用于拟穴青蟹种蟹培育的遮蔽物装置,包括养殖箱和置于养殖箱内的遮蔽物;所述养殖箱为顶端开口的四方体;所述遮蔽物为侧面开口的四方体,遮蔽物固定于养殖箱一角,其中三面 ...
