中文摘要:
      本文对滇池粘皮鯔鰕虎鱼Mugilogobius myxodermus的食物组成及摄食策略进行了初步分析。结果显示,在所有食性样本中共检出23种食物类型;粘皮鯔鰕虎鱼食物主要由枝角类、桡足类、介形类及摇蚊幼虫等组成;粘皮鯔鰕虎鱼在滇池为广食性物种,种内不同个体间食物重叠度高。这种摄食策略有利于粘皮鯔鰕虎鱼成功入侵至滇池生境。
英文摘要:
      In this paper, an alien fish species, Mugilogobius myxodermus, which newly occurred in Lake Danchi, was recorded for the first time. In order to better know how it invaded into this lake, food composition and feeding strategy of this species were investigated. The results showed that the feeding strategy of M. myxodermus in terms of the graph method suggested by Amundsen et al. (1996), was determined to be a general feeder, and they mainly preyed on cladocera, copepod, ostracoda and chironomid larvae, which were much abundant in Lake Dianchi. Owing to such an advantage in the feeding strategy, M. myxodermus invaded successfully in Lake Dianchi.
