摘　　要：为提高海水池塘的综合养殖效益,充分利用池塘冬季闲置期,2018年10月初至2019年5月中旬,利用1.33hm^(2)海水池塘,设置1000粒/m^(2)和2000粒/m^(2)两个养殖密度,开展菲律宾蛤仔“斑马蛤”新品种的越冬养殖试验。试验结果表明,“斑马蛤”初始规格324粒/kg,收获规格152粒/kg;10—11月以及翌年的3—5月生长迅速,春季生长快于秋季,但各月份的组间壳长差异均不显著;至5月初,高密度组存活率略高于低密度组;越冬养殖过程中,池水pH为7.68~8.33,悬浮物、亚硝态氮、硝态氮、氨氮、无机磷含量及化学需氧量均呈下降趋势。该新品种适宜在天津海水池塘开展越冬养殖。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 hm^(2))with 2 stocking density groups(low density group:1000 ind./m^(2);high density group:2000 ind./m^(2))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.
