| 摘 要： | 阐明了强壮箭虫营浮游动物食物，主要捕食桡足类。真刺唇角水量、双刺唇角水蚤和小拟哲水蚤是它的主要捕食对象。强壮箭虫有同种相残的弱性，但发生频率不高。其消化道内的小颗粒硅藻和甲藻并非由它主动摄入。

| Abstract: | Sagitta crassa is a zooplankton-eater mainly feeding on copepoda. .Labidocera euchaeta, Labidocera bipinnata and Paracalanus parvus comprise their main food species. Sagitta crassa are cannibalistic although the occurrence frequency of cannibalism is not high. Diatoms and dinoflagellates in the alimentary canal are not taken in intentionally by Sagitta crassa. Copepoda is the most important food group in the food composition of Sagitta crassa in four seasons, but there are remarkable changes in percentage of copepoda species consumed by Sagitta crassa. whose feeding intensity correlates negatively with water temperatures, in other words feeding intensity is lowest at high water temperature in summer and highest at low water temperature in winter. It has been shown that the winter generation of Sagitta crassa typically prefers cold |
