Crab house for cultivating soft-shell crabs and crab tower composed of the crab house

Abstract

A crab house for breeding soft shell crabs comprises a body defined by a base and a plurality of side walls. The side walls include the front side wall, the rear side wall, the left side and the right side wall. The left side wall is parallel to the right side wall. The exterior of the left side wall and the exterior of the right side wall are longitudinally provided with convex strips and / or grooves respectively. The convex strips correspond to the grooves in position and shape. When two crab houses are spliced in a left-right mode, the convex strips of one crab house are clamped into the grooves in the other crab house, at least one part of the front side wall is separated from the left side wall and the right side wall, and the portions, separated from the left side wall and the right side wall, of the front side wall are in pivotal connection with the portions, combined with the left side wall and the right side wall, of the front side wall. According to the crab house for breeding the soft shell crabs, single crabs are independently bred, the good environment is provided for crab shelling, the damage, caused by external environment, to the crabs in a traditional breeding mode is avoided, the yield is improved, the shelled soft shell crabs are collected, and the breeding process can be conveniently managed.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crab house for breeding soft-shell crabs and a crab tower composed of the crab house. Background technique [0002] The traditional method of breeding hairy crabs generally involves culturing hairy crabs from seedlings to finished products, and then selling them. During the normal breeding process, hairy crabs have to molt 18 times in their life (however, some people think that the stage of crab species should be increased by 2 times, that is, molting). 20 shells; some people think that one more shell should be added during the adult crab stage, that is, the hairy crabs in the Yangtze River Basin will moult 21 shells in their lifetime). The molting of hairy crabs not only means its development, but also a necessary step for its growth. Hairy crabs will choose a good environment for molting, and they generally choose to do it in relatively quiet, shallow water areas with ov...

Problems solved by technology

[0004] However, in the existing hairy crab breeding process, the hairy crabs are generally shelled in a natural environment, and are easily affected by the external environment during the process, such as the invasion of other aquatic organisms (the hairy crabs do not have any defense capabilities when shelling) ), the invasion of other non-shelled hairy crabs, etc. At the same time, there is no way to collect and manage the hairy crabs that have been shelled in the natural environment, resulting in a shortage of soft-shell crabs
