| 摘 要： | 分析了松花江哈尔滨段宾县石场和鸟河乡两个采样点水域野生花（Hemibarbus maculatus）、麦穗鱼（Pseudorasbora parva）、条纹似白鮈（Paraleucogobio strigatus）等三种鮈亚科鱼类消化道食物的组成,研究了这三种鱼类在河流生境下食性类型、营养级,探讨其在特定生态系统中饵料基础及鱼类间食物关系。结果表明,花属杂食性,主要摄食水生昆虫、底栖生物、浮游植物,营养级为3.86;麦穗鱼为杂食性,其食物组成为小鱼、水生昆虫、浮游动物、浮游植物,营养级为3.07级。条纹似白鮈属底栖动物食性,主要摄食水生昆虫,营养级为2.53。

| Abstract: | The food items were examined in three members of Gobioninae Hemibarbus maculatus,Pseudorasbora parva,and Paraleucogobio strigatus sampled at upper and lower Dadingzishan Dam in Songhua River to evaluate the feeding types and trophic level,and to understand the food resources and inter-species trophic interactions.The results showed that Hemibarbus maculatus as an omnivorous fish fed on aquatic insects,zoobenthos and phytoplankton with a trophic level of 3.86.The food of Pseudorasbora parva was found to be composed of fish,aquatic insects,zooplankton and phytoplankton with a trophic level of 3.07.Paraleucogobio strigatus is a benthivorous fish,mainly feeding on aquatic insects with a trophic level of 2.53. |
