摘要
本文研究了坑道内３－５ｃｍ皱纹盘鲍（ＨａｌｉｏｔｉｓｄｉｓｃｕｓｈａｎｎｏｉＩｎｏ）的摄食习性。结果表明：随海水温度变化，鲍日摄食量呈明显曲线关系，以春末夏初日平均摄食量最大；光线长期在黑暗（光强〈５０Ｌｕｘ）条件下，鲍能改变自然习性而昼夜摄食；在坑道内，３．５ｃｍ规格皱纹盘鲍生长最快，饵料系数最低；鲍对不同种海藻饵料表现出明显选择性，按喜好程度依次排列为裙带菜、海藻、石莼、鼠尾藻和羊栖菜，鲍较喜食叶片状海藻，对枝条状海藻则不太喜好。
The feeding habits of H discus hannoi of 3-5cm size in tunnel culture were studied in this paper The results showed that there is a clear relationship between feeding quantity and sea water temperature and maximum quantity in the end of spring and at the beginning of summer The natural habits can be turned into feeding day and night in the dark condition for a long time (50 Lux),and grow the fastest and have the lowerest coefficient of bait H discus hannoi has a high selectivity to different food of alga in 3 5cm they are Undaria pinnatifida,Laminaria japonica,Ulva lactuca L ,S thunbergii,Sargassum fusiforme by it's favouite degree It prefers leaf blade algae to branch algae
