The fourth sighting of the Channa argus, more commonly known as the northern snakehead fish, was recently reported, per the Missouri Department of Conservation. Yeah that a big fat NOPE for me!! https://t.co/TokPy3QSu3
WOW! Josh Shipman says he just caught a northern snakehead fish in southeast Missouri, an invasive, air-breathing fish, and it tried to escape! >>> https://t.co/Cwk8lfTROQpic.twitter.com/rcnhoOusRR
The invasive snakehead fish, native to Asia, has been recorded in Missouri for the fourth time. The snakehead caught on May 25 (not pictured) in Wayne County, Missouri was transported to the local U.S. Army Corps of Engineers (ACOE) office and recovered by an MDC agent. pic.twitter.com/bHHsp142CV
One of our lurking freshwater monsters, the Northern Snakehead, is an invasive species that can crawl out of the water and travel to the next waterway... https://t.co/qRelc0evp4pic.twitter.com/9lDF8M6rhv
外媒报导美国密苏里州近期发现俗称“北方蛇头鱼”的外来种生物入侵，据说这种鱼能够在陆地上滑行，并且呼吸空气。密苏里州环境保育部下达“革杀令”，要求一旦捕获尽速扑杀。
根据了解，所谓“北方蛇头鱼”的正式学名叫做“乌鳢”(Channa argus)，它们有鳃，也有辅助呼吸器官，只要有水汽就可以在旱灾时躲在泥中度过。自然分布于中国东部、朝鲜至俄罗斯远东地区各大水系等。乌鳢在亚洲被广泛视为一种十分美味的食用鱼，曾在美国的纽约、休士顿、奥兰多、圣路易等城市有大量贩卖，但因有部分乌鳢流出，在野外大量繁衍，成为入侵物种，对当地生态造成破坏。
外媒报导，密苏里州一名钓客在瓦帕佩洛湖捞捕到一只“北方蛇头鱼”，在旁边人行道放置数小时，“以为它会死掉，但却没有”；4个小时后被送到环境保育部时，官员检视时说：“它还活得好好的”。密苏里州环境保育部官网详细介绍“北方蛇头鱼”的特征，强调如果确认捕获，绝对不可以释放，而是建议透过“切断头部、取出内脏或者放入密封塑料袋”杀死它。
