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.
Under the laboratory conditions, the effects of different salinities (19 gradients) and temperature (17 gradients) on the growth and survival of juvenile Clams clam were studied.The results showed that the suitable salinity of juvenile clams was 6.5 ~ 39.5 The optimum salinity is 9.0 ~ 31.0, the suitable salinity is 7.3 ~ 38.7 and the optimum salinity is 15.0 ~ 23.0. The optimum temperature is 4.0 ℃ ~ 36.1 ℃, and the suitable growth temperature is 7.0 ℃ ~ 35.4 ℃. Suitable growth temperature is 17 ℃ ~ 33.5 ℃, the optimum growth temperature is 24 ℃ ~ 27 ℃. Juvenile clams have high adaptability to high temperature and low salinity.
