Feeding habits of fish assemblage in headwater streams of Chencun Reservoir in Huangshan Mountain
摘要
Abstract
Fish samples were collected from the headwater streams of the Chencun Reservoir in Huangshan Mountain in November 2010, with the feeding habits of nine dominant fish species examined. These fishes mainly fed on organic detritus, alga, and invertebrates, suggesting that they were omnivorous or invertivores. One-way ANOSIM indicated that the diet composition varied significantly with fish species, but existed part overlap (P<0. 001). The diet diversity and food niche breadth also varied significantly with fish species (P<0. 05). Generally, benthic fishes could feed on more diverse diet sources than non-benthic ones, suggesting the possible correlation between fish diet diversity and microhabitat preference. According to the index of diet overlap, there was an obvious diet overlap (D>0. 3) among the nine dominant fishes, and especially for Zacco platypus, Acrossocheilus fasciatus, Pseudorasbora parva, Rhodeus bitterling, and Cobitis rants, their diet overlap index was D>0. 9. The above-mentioned diet characteristics of the fishes could have close relations with the exogenous food supply and unstable physical habitat of the headwater streams.关键词
