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 6.5-39.5 and 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 t
emperature was 24 ℃-27 ℃. Juvenile M. meretrix had stronger adaptability to high sea water temperature and low sea water salinity.
