Shrimp and crab mixed breeding system for offshore breeding pool

Abstract

The invention relates to the technical field of aquaculture, in particular to a shrimp and crab mixed breeding system for an offshore breeding pool. The shrimp and crab mixed breeding system solves the technical problems of low breeding efficiency, low intensive degree and the like of the existing system for breeding shrimps and crabs by seawater. A system for breeding shrimps and crabs by seawater comprises a seawater purification device, a seawater warming device, a sewage treatment device, a breeding pool, a temporary breeding pool and a crab device. A breeding method comprises the following steps that A, the seawater is purified, and the purified seawater is warmed; B, the warmed seawater is conveyed to the temporary breeding pool, the breeding pool and a breeding box; C, shrimp larvas are transferred into the breeding pool, the shrimp larvas are bred into adult shrimps, and crab larvas are bred into adult crabs; D, the adult shrimps are caught, rich water is disinfected for repeated shrimp breeding, the adult crabs are caught, and the crabs are repeatedly bred. The shrimp and crab mixed breeding system has the advantages that the breeding efficiency is good, the intensive degree is high, the survival rate is high, and the like.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a shrimp and crab polyculture system used in offshore culture ponds. Background technique [0002] In the marine aquaculture industry, at present, most of them adopt the method of ecological and healthy farming in open-air ponds, and most of them adopt the mixed culture of shrimp, crab and shellfish, so that the ponds cannot be idle for many years, and there is no time for cleaning and disinfection, resulting in pond pollution, Bacteria are prone to outbreaks, and breeding benefits have been declining year after year. In order to transform and upgrade the mariculture industry, a new farming model and method must be created. The present invention adopts a fully automatic, energy-saving, environment-friendly and high-efficiency industrial facility breeding method, conforms to the direction of fishery development in my country, and is also a very effective and scientific method....

AI Technical Summary

Problems solved by technology

The high-level pond for farming improves the survival rate of shrimp seedlings, but none of the shrimp farming devices can organically combine other farming projects such as shrimp farming and crab farming, so the degree of intensification is not high enough
