Description

A culture system for seawater crabs with high efficiency

technical field

The utility model relates to a seawater crab aquaculture system for efficient sewage discharge, which belongs to the technical field of crab seawater aquaculture systems.

Background technique

According to the survey of the Fisheries Yearbook, the output of the two most important sea crabs, the swimming crab and the blue crab, has reached 270,000 tons in 2017. However, the rapidly growing market demand cannot be supplemented by the industry. The main method of farming sea crabs For pond culture, but because of the cannibalistic habit of crabs, the yield of pond culture is low. Land-based monomer farming is a farming method that can prevent crab cannibalism. This method uses a single farming method to solve the mutual cannibalism of seawater crabs and provides the possibility for the production of soft-shell crabs. However, there are certain problems in the design of such equipment on the market at present: First, in-situ water flow control devices are often used, resulting in poor sewage discharge effect of the breeding box on the side away from the drain pipe; The flow is small and the noise is large, which has a negative impact on the normal eating and activities of crabs. Third, the discharge of the residual bait of sea crabs (the shell of the shellfish of sea crabs and other large-sized residual bait) is not considered.
