Shrimp-crab mariculture system and shrimp-crab mariculture method

Abstract

The invention provides a shrimp-crab mariculture system and a shrimp-crab mariculture method, which belong to the field of aquaculture techniques and are used to solve the technical problem that existing shrimp-crab mariculture systems are low in cultivation efficiency, low in intensive degree and the like. The shrimp-crab mariculture system comprises a seawater purification device, a seawater heating device, a sewage treatment device, a culture pond, a temporary culture pond and a crab breeding device. The shrimp-crab mariculture method includes steps: A, purifying seawater, and heating the purified seawater; B, delivering the heated seawater to the temporary culture pond, the culture pond and culture boxes; C, transferring shrimp seeds to the culture pond, breeding the shrimp seeds into adult shrimps, and breeding crab seeds into adult crabs; D, catching the adult shrimps, disinfecting rich water to breed other shrimps, and catching the adult crabs to breed other crabs. The shrimp-crab mariculture system and the shrimp-crab mariculture method have the advantages of high breeding efficiency, high intensive degree, high survival rate and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and relates to a system for cultivating shrimps and crabs in seawater and a cultivation method thereof. 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 effe...

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
