System for breeding young cherax quadricarinatus in pond covered by greenhouse

Abstract

The invention discloses a system for breeding young cherax quadricarinatus in a pond covered by a greenhouse, comprising a big pond, an elevated water tank, a plurality of incubators, an insulating greenhouse and an oxygen-enriching machine, wherein a pond separating ridge is arranged in the middle of the pond, a small pond is formed between the pond separating ridge and a first short-edge slope of the big pond, the first short-edge slope is cut to form a production platform, the incubators are placed on the production platform, water inlet pipes of the plurality of incubators are connected with water outlet pipes of the elevated water tank in parallel, oxygen enriching pipes of the plurality of incubators are connected with an oxygen delivering pipe of the oxygen enriching machine in parallel, and the insulating greenhouse covers above the small pond. The system disclosed by the invention has the advantages of lower cost, capability of realizing direct circulation of pond water body in the pond, the water tank and the incubators in a better manner and keeping temperature and ecological environment of the water body in the pond at the same time, and greatly increased survival rate of the young cherax quadricarinatus and better value for popularization and application are achieved; and the cherax quadricarinatus can complete the overwintering and incubating processes in the pond, without processes of transporting the young cherax quadricarinatus for a long distance and accommodating the young cherax quadricarinatus in a new water body.

Description

technical field [0001] The invention relates to an aquatic seedling breeding pond and related facilities, in particular to a breeding system for red-clawed crayfish seedlings in a pond greenhouse. Background technique [0002] Red claw crayfish (Latin name: Cherax quadricarinatus), also known as "Australian freshwater lobster", is native to Australia. It looks like a lobster in the sea. It is one of the most valuable freshwater economic shrimp species in the world. The body color of this shrimp is brown-green, and there is a membranous bright red band on the top of the outer claw, which is beautiful and beautiful, so it is also known as red claw crayfish. The living water temperature of red claw crayfish is 5°C to 37°C, the optimum temperature for growth is 21°C to 33°C, and the optimum water temperature is 24°C to 31°C. When the temperature is lower than 5°C, it is difficult to survive. The suitable temperature for the reproduction of red claw crayfish is 22°C to 33°C, and...

AI Technical Summary

Problems solved by technology

Factors such as difficulty in natural breeding, low survival rate, and high cost of seedlings have seriously restricted the development of the red-clawed crayfish industry.
