%X Based on the survey of 8 typical sampling sites in Baiyangdian lake from June, 2009 to April, 2010, the paper described the feeding habit, the trophic level, and the food web characteristics of 25 kinds of fish in Baiyangdian lake, and analyzed the energy flow path of the fish food web, the current status and the trend of historical changes. The results showed that the feeding habits of fishes living in Baiyangdian lake included herbivore,planktonivore,benthoivore,swimming animal feeder, plankton and benth feeder, benth and swimming animal feeder. The trophic level comprised herbivore fish, omnivore fish, primary predatory fish, medium predatory fish, and senior predatory fish. It was concluded that the fish resources in Baiyandian lake was destroyed seriously, the medium predatory fish species became few, skipping trophic level occured, and the structure of food web was becoming simple and incomplete.
