Abstract

The invention relates to a shelter device and a method for an indoor cement pool for temporarily cultivating green crab young crabs. The device comprises a water tube manufactured into a frame-shaped support, wherein a mesh is laid in the frame-shaped support which is hung below a bamboo pole to enable the mesh to be horizontally laid and suspended in water. The method comprises the following steps of manufacturing the water tube into the frame-shaped support, fixedly laying the mesh in the frame-shaped support, placing the bamboo pole above the cement pool, hanging the frame-shaped support below the bamboo pole to enable the mesh to be horizontally laid and suspended in the water, and throwing the green crab young crabs into the cement pool to enable the green crab young crabs to be attached to the mesh and to be distributed stereoscopically. The shelter device and the method for the indoor cement pool for temporarily cultivating the green crab young crabs can guarantee high survivalrate of the young crabs of the green crabs and are simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of blue crab breeding, in particular to a shelter device and method for temporarily raising young blue crabs in an indoor cement pond. Background technique [0002] Juvenile blue crabs are aggressive, and killing each other is one of the main reasons affecting their survival rate. Especially under the conditions of indoor cement pond culture, due to the limited space, young crabs can kill each other seriously, and the survival rate is low. Therefore, the existence of shelter has been considered to be a key factor affecting the survival rate of young blue crabs in cement ponds. Common shelters in indoor breeding of blue crabs include clam shells, stones, broken tiles, etc. The existence of these shelters can effectively avoid killing each other, improve the survival rate, and keep the survival rate at about 80%. But the setting of these shelters is comparatively loaded down with trivial details, and brings ...
