中文摘要：采用实验生态学方法,观察了温度对织锦巴非蛤(Paphia textile)稚贝生存和生长的影响,以期为该贝中间培育场地的选择提供科学依据。结果表明:1)稚贝的48 h半致死低、高温分别为4.95、33.39℃;96 h的半致死低、高温分别为8.68、32.49℃;15 d半致死低、高温分别为12.09、31.02℃;2)在持续15 d的实验中,10℃时,稚贝在第10天全部死亡;32℃时,第15天的成活率仅为16.67%;3)以稚贝在15 d内50%个体稳定存活的高、低端温度作为生存临界温度,稚贝适宜生存温度范围为12.09~31.02℃;以成活率最高的一组或几组(组间差异不显著)为依据,稚贝最适生存温度范围为14~28℃;4)以平均日增长达到最佳组的30%所对应的高、低端温度为依据,稚贝适宜生长温度范围为16.62~31.14℃;以平均日增长最高的一组或几组(组间差异不显著)为依据,最适生长温度范围为24~28℃,最适生长温度在适宜生存温度范围内明显偏向高温端。综上,推测织锦巴非蛤稚贝适宜在南方海区潮下带水温不超过31℃的海底底播中培。

外文摘要：In this study,we observed the effects of temperature on the survival and growth of Paphia textile juveniles by using experimental ecological methods,so as to provide references for the selection of the intermediate breeding site of the juveniles.The results show that:1)The 48 h semi-lethal low and high temperatures were 4.95 and 33.39℃,respectively;the semilethal low and high temperatures at 96 h were 8.68 and 32.49℃,respectively;the 15 d semi-lethal low and high temperatures were 12.09 and 31.02℃,respectively.2)At 10℃,the juveniles all died on the 10th day,and at 32℃,the survival rate of the juveniles on the 15th day was only 16.67%.3)Taking the high and low temperatures of 50%of individuals which survived stably within 15 d as the critical temperature for survival,we found that the suitable survival temperature range of the juveniles was 12.09–31.02℃.Based on the group or groups with the highest survival rate(No significant differences between groups),the most suitable survival temperature range of juveniles was 14–28℃.4)Based on the high and low temperatures corresponding to the average daily growth of 30%of the optimal group,the suitable growth temperature range of juveniles was 16.62–31.14℃.Based on the group or groups with the highest average daily growth(No significant differences between groups),the most suitable growth temperature range of juveniles was 24–28℃,and the optimal growth temperature was obviously biased towards the high temperature side within the suitable survival temperature range.In conclusion,it is inferred that P.textile juvenile is suitable for underwater bottom sowing in the southern sea area with a subtidal water temperature below 31℃.
