摘  要:
研究了盐度、温度和pH的变化对虎斑乌贼幼体存活率及其行为的影响。结果显示,虎斑乌贼幼体分别在盐度为23、28、33,温度为17、20、23℃,pH 5.91、6.41、6.91、7.41、7.91、8.42、8.91、9.31的条件下存活率较高,均愈80%,表明幼体对于盐度、温度和pH的适宜范围分别为23~33,17~23℃和5.91~9.31,幼体在适宜和非适宜条件下行为的差异明显。幼体在温度为30℃条件下有趋热性。因此,虎斑乌贼幼体对盐度、温度和pH具有较强的耐受性。

摘  要:
The effects of salinity,temperature and pH on survival and behavior in juvenile cuttlefish Sepia pharaonis were studied in a laboratory.The survival rates of the juveniles were found high(> 80%) under a salinity of 23,28 and 33,water temperature of 17,20 and 23 ℃ and pH of 5.91,6.41,6.91,7.41,7.91,8.42,8.91 and 9.31.The juveniles had significantly different behaviors under suitable(water temperature of 17~23 ℃,salinity of 23~33,and pH 5.91~9.31) and unsuitable conditions.Moreover,the juveniles exhibited thermotaxis under the water temperature 30 ℃,indicating that the juveniles showed the high tolerance.The present study really provided important information for the aquaculture of S.pharaonis.
