| 摘 要： | 本文研究了大黄鱼仔鱼的昼夜摄食习性及生长。实验结果表明:全长5.0—5.5mm的大黄鱼仔鱼具有明显的昼夜摄食节律,白天摄食,夜间不摄食。白天有三个摄食高峰,以下午13:00最高,早上9:00和下午17:00次之。仔鱼在12日龄前生长较慢,12日龄后生长明显加快。全长与日龄之间的关系可用方程TL=3.7545e~(0.047D)表示。

| Abstract: | The present paper dealed with the feeding rhythm and larval growth of Pseudsciaena crocea. The results showed that the larvae had obvious feeding rhythm during day and night. It feed during the day, but not at night. There are three maximun feeding rates during day. One was at AM9:00 and the other two at PM13:00 and 17:00. Larvae growthed slowly before twelveth day and after that it growthed rapidly. The relationship between total length and days could be expressed as TL = 3.754e0.047D. |
