A pond greenhouse red crayfish seed breeding system

Abstract

The invention discloses a breeding system for red crayfish seedlings in a pond greenhouse, which comprises a large pond, a high-level water tank, a multi-incubation box, a heat preservation shed, and an aerator; A small pond is formed between the first short side slopes of the pond, and a production platform is cut out on the first short side slope; the incubator is placed on the production platform; the water inlet pipes of multiple incubators are connected in parallel with the outlet pipes of the high water tank , the aeration pipes of multiple incubators are connected in parallel with the oxygen supply pipes of the aerator; the heat preservation shed is covered above the small pond. The invention has low cost and can well realize the direct circulation of pond water in ponds, water tanks and incubators while maintaining the water temperature and ecological environment in the pond. The red-clawed crayfish can complete the wintering and seed hatching process in the pond, without the need for long-distance transportation of the seed and the process of adapting to the new water body of the pond. The survival rate of the shrimp seedlings is greatly improved, and it has good promotion and application value.

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 and 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.
