| 摘 要： | 在实验室条件下，研究了不同盐度（19个梯度）、温度（17个梯度）对文蛤稚贝生长和存活的影响.结果表明：文蛤稚贝的适宜生存盐度在6.5～39.5，最适生存盐度在9.0～31.0，适宜生长盐度在7.3～38.7，最适生长盐度在15.0～23.0；其适宜生存温度在4.0 ℃～36.1 ℃，适宜生长温度在7.0 ℃～35.4 ℃，较适宜生长温度在17 ℃～33.5 ℃，最适生长温度在24 ℃～27 ℃.文蛤稚贝对高温度、低盐度有较强的适应性.

| Abstract: | A laboratory test was conducted to study the effects of different sea water temperature(17 grads)and salinity(19 grads)on the growth and survival of juvenile Meretrix meretrix.The suitable and optimum sea water salinities for the survival of juvenile M.meretrix were 6.5-39.5and 9.0-31.0,and those for the juvenile growth were 7.3-38.7 and 15.0-23.0,respectively.The suitable sea water temperature for the survival of the juveniles was 4.0 ℃-36.1 ℃ ; the suitable temperature for the growth was 7.0 ℃-35.4 ℃,more suitable temperature was 17 ℃-33.5 ℃,and the optimum growth temperature was 24 ℃-27 ℃.Juvenile M.meretrix had stronger adaptability to high sea water temperature and low sea water salinity. |
