中文摘要：在室内条件下,观察不同海水盐度对文蛤(Meretrix meretrix Linnaeus)稚贝存活及生长的影响,并将168h50%死亡的盐度作为适宜生存临界盐度,将增长率30%时所对应的盐度作为适宜生长临界盐度。结果表明:在稚贝体重(13.07±3.4)mg、壳长(3.46±0.35)mm、壳高(3.16±0.30)mm,水温27.4℃～29.1℃,pH值7.8～8.2下,文蛤稚贝适宜生存盐度为6.5～39.5,最适生存盐度为9.0～31.0;适宜生长盐度为7.3～38.7,最适生长盐度为15.0～23.0。在最适盐度范围之外,稚贝的存活率、体重、壳高及壳长日增长率均随着盐度的升高或降低而降低。

外文摘要：Effects of various seawater salinities on the growth and survival of juveniles of Meretrix meretrix Linnaeus by adopting indoor measures were investigated. The salinity ensuring mortality of 50% of 168h as a period of experiment was chosen as the survival critical salinity ,while the salinity in the group with 30% as much as the highest growth rate was set to be the growth-suitable critical salinity.Based on these critical salinities,the optimum salinity suitable for the juvenile of Meretrix meretrix Linnaeus was studied. The results show that when the juvenile body weight,shell length and shell height,water temperature and pH range are 13.07±3.4 mg,3.46±0.35 mm,3.16±0.30 mm,27.4～29.1℃,7.8～8.2 respectively,the suitable survival salinity is 6.5～39.5,the optimum survival salinity is 9.0 ～ 31.0,the suitable growth salinity is 7.3～38.7,the optimum growth salinity is 15.0～23.0. When salinity is higher or lower than the optimum range,survival rate,shell and body weight daily gains drop accordingly.
