摘　　要：[Objective] The aim was to find a suitable weaning regime, including weaning period and weaning feed, for Angui//a mormorata glass eels. [Method] A weaning processing experiment was conducted indoor in fiberglass tanks, two kinds of artificial feeds （eel grower powder feed and eel grower piece feed） were selected as weaning diets against a control group fed on natural food （minced octopus flesh）, two weaning periods, 5 and 15 d, were introduced in weaning experiment. [Result] The growth rate and survival rate of the groups with 15-day＇s weaning period were higher than that of the groups with 5-day＇s weaning period, revealing that a 20% increase every 3 d from 0% to 100% in the proportion of grower paste in the minced octopus flesh during weaning is suitable for A. mormorata glass eels. [Conclusion] A. mormorata glass eels can be weaned from natural food to the commer- cially available eel grower feeds over a certain weaning period, and of the artificial feeds with same ingredients and nutrient, A. mormorata glass eels accepted powder feed more readily over 28 d than piece feed.[目的]研究探索适合于菲律宾鳗鲡仔鳗的训饵及转料方法。[方法]在室内纤维玻璃桶中开展训饵转料实验,选择人工饲料中的仔鳗粉状料和仔鳗粉碎料作为实验料,以天然新鲜章鱼糜作为对照料,设定5天和15天两个转料周期。[结果]15天转料周期的仔鳗成长率和存活率明显高于5天转料周期,每间隔3天以20%占比的速率把天然的新鲜章鱼靡替换成人工仔鳗料的转料方式,适合于菲律宾鳗鲡仔鳗的训饵转料。[结论]菲律宾鳗鲡仔鳗经过一定周期的训饵转料,能从天然饵料转到商业人工饲料,在营养成分和营养价值等同的人工饲料中,比起粉碎料,菲律宾鳗鲡仔鳗更适合接受粉状料。
