Macrobrachium nipponense high-yield culture method

Abstract

The invention discloses a macrobrachium nipponense high-yield culture method. The method comprises the following steps that 1, a pond is built, wherein the area of the pond is 1,500-3,500 m<2>, and the depth is 1-2 m; 2, the pond is disinfected, wherein the pond is cleaned with quick lime, the quick lime dosage is 7.5-20 kg / 100 m<2>, after cleaning and drying, exposure to the sun is conducted for20-30 days to use, water plants are tied into ricks to be laid at the bottom of the pond every 2 m, and water plants are planted around the pond; 3, shrimp fry stocking is conducted, wherein 12,000,000-18,000,000 shrimp fry are subjected to stocking per mu, stocking is conducted in a cloudy day or in the morning, and the stocking time is from February to March in spring and from June to July in summer; 4, feed feeding is conducted, wherein the daily feeding amount is 4-8% of shrimp weight, the feeding location is fixed to the pond side shallows, and feeding is conduced twice daily at 8:00-9:00in the morning and 18:00-19:00 in the evening; 5, water quality management is conducted, wherein the water quality is fresh, dissolved oxygen is high, the transparency is 30 cm or above, probiotics is applied, and pond water environment is improved; an impeller aerator is equipped, and the pond water dissolved oxygen content is kept at 5 mg / L or above. Accordingly, the process is simple, industrialization is easy to achieve, and the method is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for high-yield culture of Macrobrachium japonicus. Background technique [0002] Macrobrachium japonica, also known as freshwater shrimp, belongs to the phylum Arthropoda, Crustacea, Decapod order, long arm shrimp, and Macrobrachium genus. Distributed in China, Japan, Vietnam and the Far East of Russia, it is widely used in freshwater waters in various places in my country. It is the most important freshwater economic shrimp in China. Before the 1950s, wild resources were mainly used for its utilization. In the late 1950s, artificial breeding gradually began. Up to now, the main breeding areas of Macrobrachium japonicus are concentrated in the middle and lower reaches of the Yangtze River. The main provinces are Jiangsu, Anhui, Zhejiang , Jiangxi, Hubei, Hunan, Guangxi, Henan and Shandong. . [0003] The current culture process of Macrobrachium japonic...
