菲律宾鳗鲡(Anguilla mormorata)鳗苗训饵及转料方法研究

摘要

The aim was to find a suitable weaning regime,including weaning period and weaning feed,for Anguilla 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 commercially 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.
