Abstract

The invention provides a method for cultivating crayfish in a rice field. The method comprises the following steps of 1, rice field modification and building, wherein the rice field for cultivating crayfish is selected, a ridge of the rice field is heightened and reinforced, an annular cultivation ditch is dug in the periphery of the inner side of the ridge of the rice field, a water inlet and a water outlet are formed in the annular cultivation ditch, and the water inlet and the water outlet are each provided with an anti-escape facility; 2, rice field building; 3, crayfish stocking, whereinwhen rice grows to the tillering stage, parent crayfish is put into each mu of rice field at nightfall of a sunny day; 4, fodder feeding, wherein before the jointing booting stage, feeding is performed two times every day, and animal fodder is fed; after the jointing booting stage, feeding is performed according to the water temperature, when the water temperature is 24 DEG C or lower, traditionalChinese medicine fodder is fed, the feeding amount is 8-10% of the crayfish weight, and the feeding amount of the traditional Chinese medicine feed is 6-8% of the crayfish weight when the water temperature is higher than 24 DEG C; 5, rice field fertilization; 6, crayfish fishing. According to the cultivation method, production increase of crayfish and rice is promoted, and it is ensured that thecrayfish is healthy and pollution-free.

Description

technical field [0001] The invention belongs to the field of lobster cultivation, and in particular relates 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, which is especially suitable for artificial commercial farming. [0003] The breeding of crayfish is divided into natural breeding and artificial breeding. Artificial breeding includes rice field breeding (semi-artificial breeding in rice field and ecological breeding in rice field), earth pond breeding, earth pond greenhouse breeding, cement pond b...
