Description

technical field

[0001] The invention relates to a method for cultivating freshwater economical shrimps. Background technique

[0002] Procambarus clarkii is native to North America and is commonly known as freshwater crayfish. It belongs to Arthropoda, Crustacea, Crustacea, Decapod, Cricketidae in classification. It was introduced to my country in 1929 and has been widely distributed in my country. Due to the rapid growth of the market consumption and export processing quantity of Procambarus clarkii, the number of its wild resources is decreasing sharply. Therefore, increasing the production of Procambarus clarkii through artificial breeding has become an important way to meet the needs of processing, export and consumption markets. one of the important ways. At present, the pond culture method of Procambarus clarkii usually includes the preparation of the pond before stocking, stocking of broodstock, self-propagation of broodstock and larvae to grow into four major steps....
