Crab, shrimp and fish circulation culture system

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a crab, shrimp and fish circulation culture system. The crab, shrimp and fish circulation culture system is partitioned by a ridge to form two crab and shrimp ponds, and snails or crabs or shrimps are subjected to stocking in each crab and shrimp pond; flow pools are built at the two ends of the ridge, fish are subjected to stocking in each flow pool, aerobic facilities are installed at the bottoms of the flow pools, an air blower is installed on the upstream of each flow pool, a dirt collecting pond is arranged on the downstream of each flow pool, the upstream and downstream directions of the flow pools are perpendicular to the ridge, and a sewage suction pump is installed in each dirt collecting pond; a tubificidae culture pond is arranged on the position, adjacent to the corresponding dirt collecting pond, of each crab and shrimp pond, and tubificidae is inoculated into the tubificidae culture ponds. According to the crab, shrimp and fish circulation culture system, crabs, shrimps and fish are subjected to mixed culture, the water surface utilization rate is increased, output is high, and the circulation culture effect 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
