Shelter device for cultivating scylla paramamosain crab

Abstract

The invention discloses a shelter device for cultivating scylla paramamosain crabs. The device comprises a cultivating box and a shelter arranged in the cultivating box; the cultivating box is a square body of which top end is opened; the shelter is a square body of which side face is opened; the shelter is fixed at one corner of the cultivating box, another three faces are bonded to the inner walls and the bottom part of adjacent two sides of the cultivating box, one face which is not connected with the cultivating box is arranged to be an opening end. Four walls of the cultivating box are provided with circular holes, stainless steel mesh coats are covered on the circular holes. The cultivating box and the shelter are made of non-poisonous anti-corrosive hard material and PVC. Compared with a traditional cultivating pond, the shelter device is placed in the cultivating pond, sand is placed in the shelter device while the scylla paramamosain is also cultivated in the shelter device and fed from outside of the shelter device; the food residue and excrement of the scylla paramamosain can be generated out of the shelter device; after using the device, the device is convenient to change water and flush the cultivating pond, and the work load is largely reduced.

Description

technical field [0001] The invention relates to a shelter device for cultivating mud crab species, which belongs to the field of marine biological cultivation. Background technique [0002] Pseudomonas mud crabs are crabs that live along the coast of warm sea areas. The current artificial breeding method is to first select mud crabs with better gonad development from natural sea areas or breeding ponds as the species of crabs. Different species of crabs have large differences in the degree of ovary development. , It is necessary to strengthen the nutrition of the species of crabs to promote maturation and cultivate them into oviposit crabs. This stage depends on the development of the gonads of the species of crabs and environmental factors such as water temperature. It takes several days to several weeks. In the process of breeding crabs into oviposit crabs, because blue crabs have a strong sense of territory, fierce aggressiveness, and cave-dwelling habits, and the space i...

AI Technical Summary

Problems solved by technology

During the feeding process of the crab species, some food residues and excrement will be brought into the inner pool. Since the inner pool is placed on the sand surface with many shelters, it will cause inconvenience to the cleaning of the inner pool.

Secondly, during the breeding process of crabs, it is necessary to clean up the residual bait and feces every day and clean the crab breeding pond at the same time. Due to the structural setting of the sand surrounding the inner pond, part of the sand will be brought out during washing, which will block the water outlet of the breeding pond.
