Method for raising shrimp larva with soya-bean milk

Abstract

The invention provides a shrimp larva raising method, and relates to the shrimp breeding technology field. The method comprises the following steps: take 12 parts of licorice, 6 parts of arborvitae seed, 4 parts of cassia seed, 5 parts of dalbergia heartwood, 7 parts of Radix Astragali, 6 parts of red date, 2 parts of human placenta and 3 parts of Chinese angelica, and add 8 times of water for boiling for 2 hours; filter to take the liquid, and then cool the liquid to get the traditional Chinese medicine liquid for standby use; immerse soybeans in the traditional Chinese medicine liquid for 5-8 hours, then take out the soybeans to make the soya-bean milk; put the shrimp larva that are just hatched in a pool with the water depth 60-80cm; spray the soya-bean milk 2-3 times everyday over the whole pool uniformly after the shrimp larva is put in the pool, and use 0.5-1kg soybean everyday per Mu; when the body length of the baby shrimp is up to 0.8-1cm, separate the baby shrimp into several pools for raising or selling. According to the invention, the shrimp larva can grow rapidly; the physique can be enhanced; the survival rate can be raised; and the specification of the baby shrimp for selling is almost the same.

Description

technical field [0001] The invention relates to the technical field of freshwater shrimp cultivation, in particular to a seedling raising method for freshwater shrimp larvae. Background technique [0002] Freshwater shrimp (Macrobrachium nipponensis), scientific name Macrobrachium nipponensis, belongs to Crustacea, Decapod order, Longarm shrimp family. It is a rare aquatic product with strong adaptability, wide distribution, miscellaneous food habits, fast growth, tender meat, delicious taste and high economic value in freshwater waters, and is favored by consumers. The main production area of ​​freshwater shrimp is in the Yangtze River Basin, and there are large-scale farming in Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Jiangxi, Guangdong, Hunan, Hubei, Sichuan, Hebei, Henan, Shandong and other places. The total production of freshwater shrimp in the country is about 220,000 tons, of which Jiangsu Province has the highest output, accounting for about 46% of the national ...

AI Technical Summary

Problems solved by technology

[0007] However, the shortage of shrimp seedlings, especially the shortage of high-quality shrimp seedlings, has limited the expansion of the scale of freshwater shrimp farming and has become a bottleneck in the development of the freshwater shrimp industry; due to the non-standard breeding technology, the germplasm of freshwater shrimp is degraded, which makes the cultivation of freshwater shrimp more difficult. Household benefit declines; the survival rate of seedling cultivation is low, which reduces the income of farmers
