Background
The macrobrachium nipponense (macrobrachium nipponense) is a new macrobrachium nipponense with the scientific name, delicious meat, rich nutrition, rapid growth, strong adaptability and short culture period, and is an important culture variety in the fresh water aquaculture industry in China. In recent years, the freshwater shrimp aquaculture industry in China is developed vigorously, the aquaculture yield is continuously improved, and the annual yield exceeds 27.2 million tons.
At present, the freshwater shrimp is cultured by adopting a one-year two-crop culturing mode, the culturing technology is continuously improved, but the culturing process has the following problems which need to be improved: (1) in autumn, shrimp fries are disinfected by drying ponds or splashing a large amount of quicklime (bleaching powder) before stocking, so that the shrimp fries not only seriously damage aquatic weeds, but also are not beneficial to the growth of polyculture fishes; (2) the artificial shrimp nest is mainly constructed by meshes, branches and the like, so that the concealment and the space utilization rate are low; (3) the requirements of the freshwater shrimps on nutrition and culture environment are different in different growth stages, and staged feeding measures and water quality regulation and control measures aiming at different growth stages are less involved in the culture process; (4) the shrimp culture and the second generation of the offspring compete for food resources and culture space, and the commodity rate is low. How to improve the existing freshwater shrimp breeding technology aiming at the problems, improve the freshwater shrimp breeding yield and the comprehensive economic benefit, and have important significance for the sustainable development of the freshwater shrimp breeding industry.
