Cement pond net cage culture device for breeding parent crayfishes

Abstract

The invention relates to a cement pond net cage culture device for breeding parent crayfishes. The cement pond net cage culture device comprises at least four fixing rods, bearing rods and a protection structure, wherein bottom supports are arranged on the four fixing rods, the bearing rods are detachably mounted on the bottom supports, net cages are mounted on the inner sides of the bearing rods, the net cages are fixed with the bearing rods through line segments, and the protection structure is mounted on one sides of the bearing rods and used for preventing natural enemies from hurting the crayfishes. A single person in a large-scale breeding scene feeds the crayfishes in the whole pond at the same time, or when the feed stored in the inner side of the supply structure is sufficient, the crayfishes can be automatically fed without manual assistance, the automation degree is extremely high, required materials are simple, the manufacturing cost is very low, and the practicability is very high.

Description

technical field [0001] The invention relates to a cage culture device, in particular to a cage culture device in a cement pond for cultivating crayfish broodstock. Background technique [0002] Crayfish are shaped like shrimp and have a hard shell. Adults are about 5.6-11.9 cm long, and the overall color includes red, reddish brown, and pink.

[0006] Larval and female claws can be dark brown in color with a long-tipped head, often with...

AI Technical Summary

Problems solved by technology

[0007] Crayfish are usually raised in cages inside the pond, but it is very inconvenient to feed to the cages during large-scale breeding. It is undoubtedly very inconvenient to feed to each cage in the pond by boat. friendly manual work, and takes a long time
