Problems solved by technology

The disadvantage is that the breeding space in the pond has not been effectively utilized, the comprehensive benefits of breeding have not been effectively brought into play, and the breeding benefits when the survival rate of young crabs is low are not supplemented by other aquaculture objects.
However, juvenile crabs and colorful carps also have certain competition and mutual influence in feeding habits and bottom space.

specific Embodiment approach

[0017] 1. Polyculture pond conditions

[0018] The area is 2-5 mu, and the water depth is more than 50 cm; there are anti-escape facilities for young crabs around the pond and at the inlet and outlet; about a week before the crab seedlings enter the pond, transplant water peanuts to the pond, and the area of ​​water peanuts is about 1 / 2 of the pond. 4-1 / 3, and fix the water peanuts neatly with nylon ropes, so that the water peanuts can not only grow orderly in the pond, but also beautify the pond, effectively providing places for river crabs to grow and moult.

[0019] 2. Stocking crab seedlings

[0020] Crab seedlings are selected from fine varieties that have been approved or approved by the state. They are more than 4 days old, and their body color is light ginger yellow, without other variegated colors. The amount of stocking per mu is 1.0-1.25 kg. When stocking, crab seedlings should be evenly sprinkled on the water surface or aquatic plants around the pond.

Abstract

The invention discloses a mixed culture method for young eriocheir sinensis and colored carps. The method comprises the steps of (1) setting of pond conditions of mixed culture, (2) eriocheir sinensis seed breeding, (3) feeding management at the young eriocheir sinensis phase, (4) colored carp breeding, and (5) feeding management in the mixed culture period. According to the mixed culture method for the young eriocheir sinensis and colored carps, the yield and specifications of young eriocheir sinensis culture can be ensured, the survival rate and the culture specifications of the colored carps are ensured, and comprehensive pond production benefits can be better improved.

Description

technical field [0001] The present invention relates to a kind of Chinese mitten crab ( Eriocheir sinensis ) juvenile crabs and carp (Oujiang color carp) pond polyculture method. Background technique [0002] Chinese mitten crab ( Eriocheir sinensis ), commonly known as river crabs and hairy crabs, belong to Crustacea, Decapodidae, Crabidae, and Eriocheus genus. A wonderful flower of my country's aquaculture industry. At present, in my country's river crab industry chain, crab seedlings, juvenile crabs and adult crabs are basically divided into three industrial stages. The crab seedling producers are responsible for the breeding of parent crabs and the production of crab seedlings, and sell the crab seedlings to the young crab breeders for further development. Breeding; juvenile crabs are the general term for first-year-old river crabs from crab seedlings to crab species; adult crabs are commercial crabs when they reach sexual maturity, and are cultivated from crab species ...
