由於孵化出之鰻苗僅能短暫存活,故擬探討提高種鰻生殖及鰻苗活存之方法。在誘導鰻魚性腺發育方面目前仍以鮭魚腦下垂體研磨液混合促性腺激素注射之方式較佳,至於成熟之種鰻誘導產卵較適當的DHP劑量目前以每公斤鰻魚注射4mg較佳,然此方面需再作評估。鱸鰻苗以三種不同餌料飼育15週後,以鰻魚配合飼料組成長較好,其次是海鰻卵,魚肉漿較差。

研究報告摘要(英)


The Japanese eel, Anguilla japonica, is one of the most valuable species for aquaculture in Asia. At present, elvers for stocking of farms are obtained from the wild. Although induction of ovarian development and fertilization of eggs have succeeded, the larvae do not survive into leptocephali stage. The aim of present study was to investigate for artifical induced sexual maturation in females eels and try to extend the survival of eel larvae . Rearing experiments were conducted for 15 weeks to investigate the effect of diet on the growth of Anguilla marmorata. Average feed intake/fish,weight gain of artificial diets were higher than sea eel eggs and fish muscle.
