Pond polyculture method of Macrobrachium rosenbergii and bellamya

Abstract

The invention relates to a pond polyculture method of Macrobrachium rosenbergii and bellamya. The method adopts pond polyculture of Macrobrachium rosenbergii and bellamya. By the ecological purification effect of bellamya at the bottom of a pond and by fully using the residual bait of Macrobrachium rosenbergii, a good water quality environment is created for Macrobrachium rosenbergii, diseases arereduced, breeding cost is lowered, mutual benefit of shrimp and snails and double harvest of shrimp and snail products are achieved, comprehensive benefits of breeding of breeding of Macrobrachium rosenbergii are increased, and the high-quality river snail raw material is provided for the Liuzhou river snails rice noodle. In comparison with the traditional mode of main breeding of tilapia and intercropping of other fishes, the pond polyculture method of Macrobrachium rosenbergii and bellamya has the following beneficial effects: the profit per mu of the pond is increased by more than 2,000 yuan, the profit rate is increased by more than 130%, and the economical benefit is remarkable.

Description

technical field [0001] The invention relates to a method for polyculture of Macrobrachium rosenbergii and snails in ponds. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii) is an omnivorous crustacean native to Southeast Asia. It can live in various types of freshwater or brackish water. It is not resistant to low temperature and has high requirements for dissolved oxygen and water quality. It was introduced from Japan in 1976 in my country and has become the main cultured species in Jiangsu, Zhejiang, Shanghai, Guangdong, Guangxi and other provinces (cities, districts). Bellamya belongs to the mollusk of the family Viparidae. It mainly lives in river ditches, lakes, and ponds. It mostly inhabits the bottom of the water with more humus. It feeds on the skin of algae and other plants. It is a freshwater benthic animal. It is an important constituent group of the community and participates in some important ecological processes of the water ec...

AI Technical Summary

Problems solved by technology

Because Macrobrachium rosenbergii has high requirements on water quality, it is prone to water quality deterioration and lesions. During the breeding process, it is often necessary to apply more water quality improvers, which increases the cost of breeding, and the overall benefit of breeding is low.
