Mitten crab ecological breeding system

Abstract

The invention provides a mitten crab ecological breeding system which comprises a breeding pond; a plurality of hoses for conveying oxygen are laid at the bottom of the breeding pond; one end of each hose is connected with a piston through a buckle; a plurality of oxygen outlets are formed in the end face of each hose; the other end of each hose is connected with an aerator through an oxygen supply pipe; a plurality of feeding boxes are arranged in the breeding pond; the feeding boxes are connected with a guide rail through sliding blocks; the bottoms of the two ends of the guide rail are fixedly connected with a left support and a right support respectively; the end faces of the two ends of the sliding blocks are connected with a left rotating wheel and a right rotating wheel through a left cable and a right cable respectively; the left rotating wheel and the right rotating wheel pass through a left motor and a right motor respectively; a placing box is arranged at one side of the guide rail; and the placing box is connected with a second guide rail through a sliding block. By arranging the guide rail, automatic feeding of cultured fishes is achieved; and by arranging the placing box, juvenile crabs can be adaptively placed when placed, and the situation that the juvenile crabs have problems when directly placed, and then the survival rate of the juvenile crabs is affected is prevented.

Description

technical field [0001] The invention designs a breeding system, and in particular relates to a hairy crab ecological breeding system. Background technique [0002] Hairy crab is also known as river crab, crab, and clear water hairy crab. Its scientific name is Chinese mitten crab. Hairy crab is deeply favored by consumers at home and abroad for its rich nutrition and delicious meat. At present, hairy crabs have become the main aquaculture species in various places. The hairy crab farming industry has changed from "big crab farming" in pursuit of output to raising large crabs and "ecological crabs" centered on quality and efficiency. At present, the technology of artificially breeding hairy crabs is still behind. Many deficiencies, people's experience of raising crabs artificially is not perfect yet. Breeding hairy crabs requires different bait at different stages, and requires different growth environments. Many technicians ignore the scientific setting of the ecological en...

AI Technical Summary

Problems solved by technology

[0003] The present invention proposes an ecological breeding system for hairy crabs, which solves the problems of ignoring the scientific setting of the ecological environment for hairy crab breeding in the existing hairy crabs, and too many aquatic plants, resulting in reduced living space, low survival rate and reduced quality of hairy crabs
