摘要 | The growth and activity of juvenile Japanese eels Anguilla Japonica in different pigmentation stages from the glass eel to the elver stage were studied in the laboratory at 15, 20 and 25degrees C. The growth and activity of the eels were significantly influenced by both temperature and fish size. Growth rate generally declined with increasing fish size, and fish were least active and experienced a low growth during the pigmenting stage at all temperatures. They were nocturnal and spent significantly more time moving (swimming, feeding and moving over the substratum) at 20 and 25degrees C than at 15degrees C at night within each pigmentation stage. Accordingly, they grew significantly Faster at 20 and 25degrees C than at 15degrees C throughout the study. The development of pigmentation appeared to be dependant on water temperature but not on fish size. This study suggested that the growth and activity of juvenile Japanese eels were positively correlated, because fish were least active and grew slowest at low temperature (15degrees C) or during the pigmenting stage at all temperatures.
