Rice field cultivation method for misgurnus anguillicaudatus

Abstract

The invention discloses a rice field cultivation method for misgurnus anguillicaudatus and relates to the field of aquaculture. The method comprises the following steps: selecting a pollution-free parcel of a rice field, and finishing basic facilities for cultivating the misgurnus anguillicaudatus in the rice field, wherein soil is loam or clay, the pH value is 5.5-7, and the parcel area is 333-2,000 m<2>; after rice turns green, draining water in the field completely, and exposing for 3 days, wherein the applying amount of an organic fertilizer is 50 kg/mu; adding water to be 20-30 cm, putting 75 kg of loach species with the size of 5-6 cm per mu, and feeding artificial feeds once at each day, wherein the feeds are special hard granulated feeds for the misgurnus anguillicaudatus, and the daily feeding amount accounts for 3-4 percent of the body weight of the misgurnus anguillicaudatus. The rice field cultivation method for the misgurnus anguillicaudatus provided by the invention is simple in operation process; the misgurnus anguillicaudatus is cultivated by using the rice field; the yield per mu of a paddy field can be increased, the cultivation scale of the misgurnus anguillicaudatus can be expanded, and the development of the misgurnus anguillicaudatus cultivation industry is promoted. Compared with a conventional method, the method has the advantages that the survival rate of the cultivated misgurnus anguillicaudatus is higher; the growth speed of the misgurnus anguillicaudatus is higher; the quick growth of the misgurnus anguillicaudatus can be promoted by the adoption of a traditional Chinese medicine composition, and the stress response of the misgurnus anguillicaudatus is reduced; by adjusting a rice field fertilization method, the adverse effect on the misgurnus anguillicaudatus caused by rice field fertilization is reduced.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating loach in paddy fields. Background technique [0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor that restricts the efficiency of loach farming is the slow growth rate of loach, and it is difficult to achieve more than 3 times the annual growth rate; at present, pond culture is mainly used for loach farming, but the ponds that can be used for loach farming are limited, and the output of loach can n...
