Rapid breeding method for shrimps in rice field

Abstract

The invention provides a rapid breeding method for shrimps in the rice field. The method comprises the steps of rice field pretreatment, stocking management and seedling culture management, and specifically comprises the steps that after a pond is dried in the sun and disinfected, enriched sludge is laid in the rice field, water is injected into the rice field, waterweeds are planted on the periphery of the rice field at intervals, elodea nuttallii is planted in circular ditches, and air stones are placed; the rice field is divided into a region A and a region B, a seedling net is arranged in the center, and fortified feed is fed to obtain fortified shrimp seedlings; in the early stage of rice seedling transplanting, fixed-point feeding places are set, breeding feed is fed every day, and seedlings are transplanted to the tillering stage; the water depth is adjusted, and water pumping and changing, breeding feed feeding and night light irradiation treatment are conducted; and supplementary feed is regularly fed at night. By means of the rapid breeding method for the shrimps in the rice field, the weight gain rate of the obtained rice field shrimps can reach 310%, the meat content is increased to 22.2%, the total protein content of the shrimps is larger than or equal to 53.2 g / L, the survival rate is 97.5% or above, parent shrimps can be additionally put into the rice field shrimps for continuous breeding when the first batch of rice field shrimps are harvested, and the breeding efficiency and economic benefits of the rice field are fully improved.

Description

Technical field [0001] The present invention relates to bonding techniques ecological system, and in particular relates to a method for rapid paddy farming shrimp. Background technique [0002] The current "grow combination of" rice fields shrimp farming model, it has become an important mode of production. But in the breeding process, crayfish susceptible to stress response due to changes in the external environment, seriously affecting their feeding, leading to abnormal activity and weaker physical phenomena, and even cause death, but also because of the impact the stress response Shelling the number is reduced, resulting in low survival rate of finished shrimp, meat decreased quality deterioration and other problems. At the same time the stress response crayfish if not properly controlled, it will also affect the production of quality rice. [0003] Chinese patent CN113424786A discloses a paddy field layout, breeding Taipa set, remove predators, seed delivery, bait feeding, Au...

Problems solved by technology

However, the existing cultured rice field shrimp takes a long time, and does not involve the quality of the rice field shrimp after harvest.
