摘  要：
研究了温度和盐度变化对大泷六线鱼Hexagrammos otakii Jordan et Starks仔鱼存活与生长的影响。结果表明,大泷六线鱼初孵仔鱼及10日龄仔鱼在温度4～16℃范围内都能存活与生长,存活率均在84%以上,温度为20℃试验组的存活率均低于50%。盐度渐变条件下,盐度10～30范围内存活率都大于90%,在盐度为5及以下时仔鱼的存活率降为0,仔鱼对高盐度的适应能力较差。盐度突变条件下,盐度25和30的试验组仔鱼的存活率都在95%以上,盐度10～20的试验组仔鱼出现不同程度的死亡,存活率可达56%～75%。大泷六线鱼仔鱼的最适生长温度为12～16℃,最适生长盐度为25～30。

摘  要：
The effects of temperature and salinity on the survival and growth of larval Hexagrammos otakii Jordan et Starks were studied.It showed that the newly-hatched larvae and 10 dph larvae of H.otakii Jordan et Starks could survive and grow at temperature of 4~16℃,with the survival rate of more than 84%,while the survival rate was below 50% at 20℃.Under gradual salinity change,the survival rate was more than 90% at salinity of 10~30.The survival rate was zero when the salinity was 5 and below,and the ability of adapting to high salinity was also poor.Under sudden salinity change,the survival rate was more than 95% at salinities of 25 and 30,and the survival rate was 56%~75% at salinity of 10~20.The most suitable temperature range is 12~16℃,and the most suitable salinity range is 25~30 for H.otakii Jordan et Starks.
