Study on the Food Web of Fish in Baiyangdian Lake Based Diet Analysis
Abstract:Based on the survey of 8 typical sampling sites in Baiyangdian Lake from June 2009 to April 2010,the paper studied 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 Baiyangdian 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.
Keywords:Baiyangdian Lake  fish  food web  trophic level
