Description

Healthy breeding system of portunid

Technical Field

The invention belongs to the technical field of aquaculture equipment, and particularly relates to a culture system for improving the temporary culture survival rate of sea-caught swimming crabs.

Background

The method is a production mode which develops from practical production and efficiently utilizes natural portunids, mainly utilizes the quantity and price advantage of natural portunids in the sea area of 9-11 months to purchase the wild portunids caught by the sea, and after a period of fattening temporary culture, the wild portunids are put on the market, and the profit is obtained by utilizing the market price difference. However, in recent years, with the further development of the industry, various problems are gradually developed, and especially the problem of low survival rate of temporarily breeding and fattening the sea crabs becomes an important factor influencing and restricting the stable and continuous development of the industry. One of the important factors causing low survival rate of temporarily-cultured swimming crabs for sea catching is frequent disease occurrence, and the traditional culture system has the defects of difficult application and poor medicated bath effect during disease treatment, so that diseased crabs cannot be effectively treated, and therefore, the problem to be solved at present is to design a culture system capable of accurately administering the drug and improving the survival rate of the swimming crabs.

The prior art provides some solutions, such as prior patents: this patent of wisdom farming systems TWM587896U provides a wisdom farming systems for cultivateing aquatic products, and the purpose of bait casting, decontamination is accomplished to high efficiency, adopts some rows of supervisory equipment can observe the breed object in real time simultaneously, ensures that the breed object survives healthily and reaches the purpose of breeding automation, intellectuality.
