養殖所需鰻苗多賴天然捕獲，鰻苗資源有限，導致產業面臨萎縮之壓力。故需建立鰻魚人工繁殖技術，維持鰻魚等相關產業穩定發展。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，由以往試驗雌雄種鰻人工催熟結果可知藉由觀察胸鰭顏色的改變及泌尿生殖口張開程度可分別判斷生殖腺發育情況及誘導產卵時機。 本研究擬持續進行種鰻培育、種鰻人工催熟注射及鰻苗飼育試驗，期能建立較適合的鰻魚人工繁殖方式。

This study try to explore the suitable methods for induced spawning of the japanese eel (Anguilla japonica). Artificially induced sexual maturity of the eel used homogenized salmon pituitary mixed gonadotropin injection and mature female eels induced spawning used DHP injected. The results showed , we can decide the degree of gonadal development and the appropriate time for induced spawning of the eel by observing the color change of pectoral fin and urogenital opening , respectively.
