| 摘 要： | 根据1990年10月～1991年9月在山东烟台近海采集的魁蚶样品观察和分析,结果表明,魁蚶的食物组成比较简单,以摄食植物性饵料为主,兼食浮游动物。主要种类有硅藻门的圃筛藻、舟形藻、菱形藻、曲舟藻、沟直链藻和粗纹藻以及浮游动物中的挠足类。除冬季外,魁蚶在其他季节均摄食。摄食的种类主要取决于自然海域中硅藻类等优势饵料生物种类的季节变化。

| Abstract: | The present paper deals with-the feeding habits and seasonal variation of diet of Scapharca broughtonii,which were based on 207 stomachs collected from Yantai of- fshore sea from Oct.1990 through Sept.1991.The results are following: 1) The food composition of Scapharca broughtonii is simple,which include phy- toplankton mainly and zooplankton.The main species are Coscinodiscus sp.,Navicula sp.,Nitzschia sp.,Pleurosigma sp.,Melosira sulcata,Trachyneis aspera and Cope- poda. 2) Except January and February,Scapharca broughtonii takes food all the other months.The food kinds depend on the seasonal variation of dominant biological forage sDecies in the sea,such as Bacillariophyta. |
