Crab, shrimp and fish recirculation farming system

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to a crab, shrimp and fish circulating culture system. The crab, shrimp and fish circulating culture system is divided into two crab and shrimp ponds by a ridge, and bellamya quadrata, crabs or shrimps are cultured in each crab and shrimp pond; flowing water tanks are built at the two ends of the ridge, fishes are cultured in each flowing water tank, an oxygenation facility is installed at the bottom of each flowing water tank, an air blower is installed at the upstream part of the flowing water tank, a dirt collection tank is arranged at the downstream part of the flowing water tank, the upstream and downstream directions of the flowing water tank are perpendicular to the ridge, and a dirt suction pump is installed in the dirt collection tank; and a tubificidae culture pond is arranged in a position, adjacent to the dirt collection tank, of the crab and shrimp pond, and tubificidae are inoculated in the tubificidae culture pond. According to the crab, shrimp and fish circulating culture system, the crabs, the shrimps and the fishes are subjected to polyculture, so that the utilization rate of the water surface is increased, the yield is high, and the effect of circulating culture is achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a crab, shrimp and fish circulation breeding system. Background technique [0002] Crab and shrimp pond culture refers to the mixed culture of river crabs, freshwater prawns, crayfish, and crabs and shrimps in the pond. Generally, fish polyculture is not carried out in crab and shrimp ponds. [0003] Flowing water aquaculture is the use of continuously flowing water bodies for the cultivation of aquatic animals. It has the characteristics of short breeding cycle, small occupied area, high density, high yield, high benefit and convenient management. The water body of running water aquaculture is constantly updated, so that the cultured fish can grow rapidly under the conditions of optimal water temperature, water quality, dissolved oxygen, and bait. At present, the main forms of flowing water aquaculture are natural flowing water aquaculture, warm flowing water ...

AI Technical Summary

Problems solved by technology

[0005] Due to the low output of crab and shrimp farming, the general yield is only about 100 kg per mu, resulting in low utilization rate of water bodies; the output of flowing water farming is high, but it needs to consume a lot of water resources and produce a lot of pollutants; circulating aquaculture has water treatment costs high problem
