摘　　要：在实验室特定条件下，测定大小２种规格草鱼对禾本科（Ｇｒａｍｉｎｅａｅ）和豆科（Ｌｅｇｕｍｉｎｏｓａｅ）的３２种牧草每日的最大摄食量，以确定其对３２种牧草的嗜好性．结果表明二者对其中的大多数牧草有共同嗜好性，它们都喜食禾本科（Ｇｒａｍｉｎｅａｅ）牧草，其中最喜食匍匐剪股颖，而对落花生叶等１０种豆科（Ｌｅｇｕｍｉｎｏｓａｅ）牧草均不摄食，对紫羊茅等６种牧草二者的嗜好程度有差异．Under laboratory conditions(water temperature 24 ℃,pH=7,dissolved oxygen 8 mg/L),several measurements were made on the daily maximum consumption of thirty-two herbages of Gramineae and leguminosae to determine hobbies of various herbages by two groups of grass carps.The research results indicate that they have common hobbies on most of the herbages.Herbages of Gramineae were most consumpted(such as Agrstis plastis Huds)while ten kinds of herbages of Leguminosae(such as Arachis hypogaea Linn.)were not consumpted.There are some differences in hobbies of six kinds of herbages(such as Fescue rubra L.)for two groups of green carps.
