摘要
对不同温度下黄颡鱼仔鱼的摄食强度及抵达不可逆点(PNR)时间的变化进行初步研究。结果表明,黄颡鱼仔鱼的摄食强度随温度升高而增大;仔鱼抵达PNR的时间随温度升高而缩短,在24～28℃下,仔鱼的PNR点出现在出膜后的7～8 d。实验结果显示,28℃是比较适宜黄颡鱼仔鱼生长的水温。
Feeding intensity and point-of-no-return （PNR） of Peheobogrus fulvidraco larvae at different temperatures were studied under laboratory conditions. The results showed that the feeding intensity of P fulvidraco larvae increased with increasing temperature, but high temperatures could shorten the PNR. At the temperature of 24-28℃, the PNR was about 7-8 days after hatching. It suggested that the suitable living temperature for P. fulvidraco larvae was 28℃.
