Method for culturing procambarus clarkia in same pond in three seasons in one year

Abstract

The invention relates to a method for culturing procambarus clarkia in the same pond in three seasons in one year. The method comprises the steps that 1, an excellent group with the optimal comprehensive performance is screened out from local procambarus clarkia groups in the middle and lower reaches of Yangtze river so as to be used as breeding parents; 2, 400 fry of parent procambarus clarkia are cultured in each 666 m<2> of water surface; 3, in the commercial procambarus clarkia culturing season in the second season of the second year, commercial procambarus clarkia with the weight over 35 g is captured, and young procambarus clarkia with the weight lower than 35 g is left in the pond to continue to be cultured; 4, a net is inserted 30 cm under the water surface in July in the ommercial procambarus clarkia culturing season in the third season of the first year, so that procambarus clarkia is prevented from digging holes; 5, all commercial procambarus clarkia is captured in the last ten-day period in August in the same year, sufficient parents are left, and circulation of culturing of fry in the first season in the first year is conducted in the end of August. The method has the best advantages that procambarus clarkia is made to be adapted to an artificial ecological system of the same pond at the early stage, and the pond culturing mode is optimized.
