| 摘要: |
| 根据1995年3月至1997年6月在道观河水库采集的大银鱼和浮游动物指标对不同生长期大银鱼的食物种类,主要食物出现率,肠充塞度以及鳃耙结构和饵料基础浮游动物进行了分析,得出大银鱼鳃耙间距随体长增长而增大,所摄物亦由小到大;大银鱼食物种类与其环境中的饵料基础种类呈相反消长关系;肠充塞度与生长呈正相关关系. |

| Abstract: |
| This paper discussed the food species and its present frequency, intestine fullness, gill rake structure and food species, based on Protosalanx hyalocranius and zooplankton taken from Daoguanhe Reservoir from March 1995 to June 1997. It showed, with Protosalanx hyalocranius grown, that the distance between gill filters and the food size increased. There existed anegative relationship of food species in intestine and in the environment and a positive relationship of the intestine fullness and growth. |
