Two treatments were carried out in Go Cong district of Tien Giang province each treatment was repeated three times treatment 1 culture in raceway code canal the treatment 2 in stationary water blood cockle and extensive shrimp culture mixed together code blood- shrimp . Water level in pond was from 1 2-1 4 m sediment in the bottom of the pond was 20-30cm area of pond was 300-500m2 seedling was from natural origin and average size was 4 3 g ind stocking density was 87-145 ind m2. Results showed that blood cockle can treat partly waste from shrimp pond average weigh of blood cockle after 6 months in canal and blood-shrimp models were 12 2 1 84 g and 12 5 _1 27 g respectively there is no significant about growth. In blood cockle mixed with shrimp model is good to grow of blood cockle there is no significant between stationary water and raceway condition protein and fat of blood cockle was 63 34 -68 91 and 10 18 - 14 13 Protein in meat blood cockle in blood cockle -shrimp treatment was higher than and significant different with before experiment. Model of blood cockle was expected high income 22.660.220 VND ha year and make clean environment absorb suspended solid 198 kg ha year. Keywords Anadara granosa stationary pond. Title Experiment on of blood cockle Anadara granosa on lentic earthern pond.
