Abstract：To increase economic performance and production efficiency, the overwinter culture experinment was conducted from Oct, 2018 to May, 2019 in Tianjin, during the idle time of seawater ponds(1.334 hm2) with 2 stocking density groups(low density group: 1000 ind./m2; high density group: 2000 ind./m2) of “Zebra” strain of Manila clam Ruditapes philippinarum. Results showed that the clam grown from 324 ind./kg to 152 ind./kg; in the trial, clam obviously grown in 2 periods(autumn: Oct. to Nov., 2018; spring time: Mar. to May, 2019).Though clam grew faster in spring in shell length each month, there was no significant difference. By the end of the experinment, the survival rate was higher in high density group than that in low density group. During the experinment, the levels of suspended solids, nitrite nitrogen, nitrate nitrogen, ammonia nitrogen, inorganic phosphorus, and COD in the ponds were declining with pH of 7.68—8.33. This new strain of Manila clam could be overwinter culture in seawater ponds in Tianjin.
