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 present embodiment, the specific design of this system is as follows: the crab shrimp pond 1 middle of a 30 mus is separated into two pieces with soil ridge, respectively builds 2 120 square meters at the two ends of middle ridge The flow pool 2 of meters, the upstream of each flow pool 2 is installed a 2.2 K blower, and the bottom of the flow pool 2 is equipped with microporous aeration facilities. 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.

[0025] In the flow pool 2, stocking specifications are 50 snakeheads / kg, and the stocking density is 150 tails / square meter. The constant flow o...

Embodiment 2

[0030] 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:

[0031] 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.

[0032] 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 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 ...
