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

Embodiment 1

[0024] Such as figure 1 Shown, be the crab shrimp fish circulation culture system of the present embodiment, the concrete design of this system is as follows:

[0025] A 30-acre crab and shrimp pond 1 is separated into two pieces with soil ridges in the middle, and two 120 square meters of flow pools 2 are respectively built at the two ends of the middle ridge, and a blower fan of 2.2 k is installed in the upstream of each flow pool 2, and the flow water Microporous aeration facilities are installed at the bottom of pool 2. The downstream of each end flow pool 2 builds a sewage collection pool 3 of 12 square meters, and a sewage suction pump is installed in the sewage collection pool 3, and builds a 120 square meter pool adjacent to the sewage collection pool 3 and near the crab and shrimp pond 1 Water worm culture pond 4, build ecological ditch 5 on the ridge of the pond.

[0026] In the flow pool 2, stocking specifications are 50 snakeheads / kg, and the stocking density is ...

Embodiment 2

[0031] Such as figure 1 Shown, be the crab shrimp fish circulation culture system of the present embodiment, the concrete design of this system is as follows:

[0032] A crab and shrimp pond 1 of 20 mu is separated into two pieces with soil ridge in the middle, respectively build 3 flow pools 2 of 110 square meters at the two ends of the middle ridge, each flow pool 2 upstream installs a blower blower of 2.2 watts, and the flow pool 2 Microporous oxygenation facilities are installed at the bottom. The downstream of each end flow pool 2 builds a sewage collection pool 3 of 22 square meters; Water worm culture pond 4, builds ecological ditch 5 on the pond ridge, and ecological ditch 5 is positioned at the both sides of crab and shrimp pond 1, is parallel with field ridge.

[0033] In the flow pool 2, stocking specifications are 20 tails / kg of grass carp, and the stocking density is 200 tails / square meter. The constant flow of water is always maintained in the pool, and the wat...

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 ...
