摘要
根据消化道内食物分析结果得出 :涟虫类 (细长涟虫 ( Iphinoe tenera)、三叶针尾涟虫( Diastylistricincta)和驼背涟虫 ( Campylaspissp.)、瓣鳃类 ( Lamellibranchia)后期幼虫和腹足类 ( Gastropoda)后期幼虫都营浮游植物食性 ,以硅藻类为主要食物。细长涟虫以星脐圆筛藻、未查明的圆筛藻和辐射圆筛藻为主要摄食对象 ;三叶针尾涟虫以舟形藻和新月菱形藻为主要摄食对象 ;驼背涟虫以辐射圆筛藻为主要摄食对象。瓣鳃类后期幼虫以辐射圆筛藻和未查明的圆筛藻为主要摄食对象 ;腹足类后期幼虫以未查明的圆筛藻、辐射圆筛藻和中心圆筛藻为主要摄食对象。
s The resaults of food habit analysis of the alimentary canals show that: Cumaceans (Iphinoe tenera, Diastylis tricincta and Campylaspis sp.), post larvae of lamellibranchids and gastropods are phytoplanktonivorous, feed mainly on diatonms. Coscinodiscus asteromphalus, Coscinodiscus sp. and Coscinodiscus radiatus are the main preys of Iphinoe tenera; Navicula sp. and Nitzschia closterium are the main preys of Diastylis tricincta; Coscinodiscus radiatus is the main prey of Campylaspis sp.; Coscinodiscus radiatus and Coscinodiscus sp. are the main preys of post larvae of lamellibranchids; Coscinodiscus sp., Coscinodiscus radiatus and Coscinodiscus centralis are the main preys of post larvae of gastropods.
