In Eastern Canada, non-native plant and animal species are a concern to biologists. Bringing non-native species such as invasive fishes into Canada can damage the environment and ecosystem by repressing native species due to food competition or preying. Invasive fishes enter the fresh waters of Canada in several ways including drifting, deliberate introduction, accidental release, experimental purposes and, most commonly, through the attachment on international boat hulls. ==Species at risk== Of the fish and other marine life under threat in Canada the primary threat is loss of habitat and degradation, followed by alien invasive species. Fifteen invasive species of fish and two invasive species of plant are reported to affect native listed wildlife. The two most common of them are the brown bullhead (''Ameiurus nebulosus'') and the pumpkinseed (''Lepomis gibbosus''). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aquatic invasive species in Canada」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
