The aquatic environmental conditions of Sunqiao canals in Chuansha County, larva cultivation, distribution of stock, yields and assessment of quantity of freshwater shrimp (Macrobrachium nipponense) after artificial releasing were mainly studied in this paper. The water temperature of the canal was suitable for freshwater shrimp. The water quality was good enough for growth and propagation of freshwater shrimp. The results showed that the yields of freshwater shrimp during 1987-1989 (before artificial releasing) were 1451. 23 kg and 3268. 95 kg during 1990-1991 (after releasing). The latter is 2.25 times of the former. The good results of artificial releasing of freshwater shrimp have been proved.
