Problems solved by technology

[0003] In recent years, crayfish has become an important economic breeding species in China. The market price is getting higher and higher, and the demand is increasing, which drives the development of artificial breeding. At present, there are few crayfish in rice fields. Due to improper use of breeding methods, the output The lobsters are small, the meat quality is poor, and the survival rate is low, which reduces the income of the farmers. At the same time, artificial feeding has a lot of feed, which not only increases the cost of breeding, but also makes the quality of the lobsters worse, and they cannot be sold at a good price. Excessive use of chemical fertilizers not only reduces the quality of lobsters, but also pollutes water resources and soil, which is not conducive to sustainable development

Abstract

Provided is a method for breeding crayfish in a rice field. The method comprises the following steps of (1) rice field preparation, (2) rice field transformation, (3) rice field disinfection, (4) seedling planting, (5) crayfish seedling stocking (6) fodder feeding, (7) rice field fertilization and (8) crayfish catching. The method for breeding the crayfish in the rice field makes the breeding of the crayfish more rational, environmentally friendly, and forms an ecological farming method with virtuous circle by combining with rice field culture.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a method for cultivating crayfish in rice fields. Background technique [0002] Freshwater lobster, commonly known as crayfish, belongs to the class Arthropoda Crustacea and Decapod Lobster family. It has a thick head and chest, a hard shell, and delicious meat. It is a nutritional and nourishing food with low fat, low cholesterol and high protein. Freshwater lobster not only has a large body and plump meat, but also has the characteristics of short growth cycle, high yield and strong adaptability to miscellaneous food. [0003] In recent years, crayfish has become an important economic breeding species in China. The market price is getting higher and higher, and the demand is increasing, which drives the development of artificial breeding. At present, there are few crayfish in rice fields. Due to improper use of breeding methods, the output The lobsters are small, ...
