Description

Circulating aquaculture system for breeding blue crabs

Technical Field

The invention relates to aquaculture, in particular to a circulating water aquaculture system for breeding blue crabs.

Background

The blue crabs are one of the important mariculture varieties in the aquaculture industry of China, the aquaculture industry is still in the early development stage, most of the seedlings come from natural water areas, and the phenomenon that the seedlings are not put in the aquaculture pond sometimes occurs. At present, a plurality of factors influencing the egg laying quality of the blue crabs exist in the artificial breeding process of the blue crabs, so that the blue crabs are extremely unstable in time, quality and quantity. The problems of death of the crab seeds, less egg laying amount, large abortion amount and the like exist in the egg laying process.

The past research on recirculating aquaculture systems has mainly focused on the aspects of water treatment effect, biological membranes, process flow, system construction, aquaculture benefits and the like. At present, most of industrial circulating water culture systems need to be equipped with large-scale water treatment equipment and instruments, such as a protein separator, a blower, a sand filter tank, a filter barrel, ultraviolet disinfection, ozone disinfection, a water pump, a cooling machine and a warming machine. The problems of expensive cost, high maintenance cost, high operation cost and the like of the instruments and equipment generally exist. The breeding of the young blue crabs is developed by combining the industrialized breeding and the pond ecological breeding, and the problems of fattening and oviposition quality mainly exist in the industrialized breeding process of the young blue crabs. The gonad development of the blue crabs is a staged process, the gonads are difficult to completely develop in a short time under the condition of industrial cultivation, even if the gonads are well developed, the laying quality of the blue crabs is uneven due to the limitation of the cultivation environment and the limitation of nutrition acquisition, and the cultivation of the breeding crabs even further influences the development and survival of larvae. In the egg laying process of the green crabs cultured in an industrialized way, the problems of small egg laying amount and serious abortion often occur due to the uncertainty of egg laying substrate and culture environment. Thereby greatly influencing the breeding process of the industrial young blue crabs.

Therefore, the establishment of the circulating water culture system for cultivating the green crabs with the characteristics of stable water quality, high survival rate of breeding crabs, good spawning effect, simple and convenient management, low operation cost and the like is necessary, and the development of the circulating water culture system in the industrial circulating water full-artificial breeding has great practical significance and application value.
