本年度擬探討誘導種鰻自然產卵之時機以提高自然產卵比率及探討鱸鰻之養成技術，以供往後鱸鰻養殖試驗的參考。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方面以每公斤鰻魚注射4mg DHP有較佳之誘導效果。不同餌料對鱸鰻成長之影響試驗結果，發現成長率以魚苗配合飼料組最佳，其次是鰻魚配合飼料組、香魚浮料組，而香魚沉料組較差。常用藥物對鱸鰻苗之急性毒試驗結果，七種藥物以高錳酸鉀毒性最強，其次分別為美舒添、硫酸銅、碘、BHC-80、漂白水及福馬林。

This study try to explore the suitable methods for induced spawning of the japanese eel (Anguilla japonica) and to investigate the appropriate methods of aquaculture for Anguilla marmorata . Artificially induced sexual maturity of the eel used homogenized salmon pituitary mixed gonadotropin injection and mature female eels induced spawning used DHP(4mg/Kg body weight)injected seem to have better effects. The results of feeding different diets on the growth rate of Anguilla marmorata showed tha t feeding commercial fry diets have the best growth rate, followed by feeding with eel diets group , ayu expanded pellet group and ayu pellet diets group. The results of acute toxicity tests of Anguilla marmorata showed that potassium permanganate is the most toxic to Anguilla marmorata , followed by masote, copper sulfate, indine, BKC-80, hypochlorit and formalin .
