Abstract

The present invention discloses a high-efficiency ecological cultivation method for macrobrachium nipponense. The method comprises: (1) preparing a shrimp pond; (2) disinfecting the shrimp pond; (3) planting and managing water weeds; (4) stocking and managing postlarvae; (5) carrying out oxygenation water quality management and oxygenation; (6) carrying out feeding management; and (7) catching adult shrimps. According to the present invention, the high-efficiency ecological cultivation method for macrobrachium nipponense is simple and easy in operation, can greatly reduce content of poisonous and harmful organic matters, residual feed and the like by virtue of management methods such as planting water weeds, matching filter-feeding fishes, reducing a mixed feed proportion, reasonably and effectively feeding, controlling water weed density, carrying out oxygenation by virtue of an aerator, and the like, thereby reducing cost investment and keeping water quality freshness. by postponing shrimp postlarvae stocking time and applying quicklime, occurrence of autumn propagated postlarvae can be inhibited; and by leaving an area besides a pond with no water weeds planted, feeding and growing of macrobrachium nipponense can be promoted. The macrobrachium nipponense cultivated by the method is high in yield, good in quality, high in large-size commercial shrimp rate, good in cultivation benefits, so that the health development of macrobrachium nipponense cultivation industry is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency ecological breeding method for freshwater shrimp that can improve the yield and quality of freshwater shrimp cultivation. Background technique [0002] Freshwater shrimp, also known as river shrimp, scientific name Macrobrachium nipponense (Macrobrachium nipponense), belongs to crustaceans, decapods, swimming suborders, true shrimp pie, Longarmidae, Macrobrachium genus, and is a major economic species widely distributed in freshwater waters. shrimp. Green shrimp is rich in nutritional value, tender and delicious in taste, and is a famous and precious aquatic product that is loved by people. The economic value of freshwater shrimp is very high, and it is one of the traditional economic shrimp species in the freshwater aquaculture industry in my country. But at present, due to the disadvantages of slow growth, high feed cost, low output, and small size in fr...
