中文摘要:采用试验生态学方法,在温度8~34℃、海水盐度为29.0、初始稚贝平均壳高为(1.77±0.21)mm、壳长为(2.89±0.32)mm的室内控温的条件下,研究了温度对施獭蛤(Lutraria sieboldii)稚贝生长和成活的影响,以期为稚贝的中培提供基础材料。结果表明,稚贝适宜生存和生长的温度范围分别为16.3~31.5℃和18.5~31.8℃,最适生存和生长的温度范围分别为25~28℃和25~30℃;最适生存和生长温度在适宜温度范围内明显偏向高温端,随着温度的升高或降低,稚贝的成活率、壳长和壳高的日增长均呈现逐渐下降趋势,高温端下降速率显著高于低温端;在低温端,稚贝壳长日增长速度滞后于壳高的日增长速度,壳长生长受抑制,但在最适生存温度25~28℃范围内,壳长日增长速度比壳高快,壳长生长能力强于壳高,与前述现象相反,在高温端这种倾向不明显。

外文摘要:We studied the effect of temperature on the survival and growth of juvenile Lutraria sieboldii [ average shell height: (2. 89 ± 0. 32) mm, average shell length : (1.77 ± 0. 21 ) mm] at salinity of 29. 0 and temperature of 8 ± 34 ℃. The results reveal that the suitable temperatures for survival and growth of juveniles were 16. 3 31.5℃ and 18.5 - 31.8 ℃, respectively; the optimum temperatures for survival and growth were 25 - 28 ℃ and 25 - 30 ℃, respectively. The optimum temperatures for survival and growth bent towards high-temperature side obviously. The survival and daily growth rate of juveniles' shell length and height showed a decrea- sing trend and high-temperature side decreased more significantly than low-temperature side. On low-temperature side, the daily growth of shell length was slower than that of shell height; however, range of 25 ~ 28 ℃, which was contrary to the aforementioned trend, the former exceeded the latter within the optimum temperature but was unobvious on high-temperature side.
