乌鳢俗称"黑鱼"，是凶猛的肉食性鱼类，位于淡水生态系统的顶端。具有特殊的鳃上器官，可短暂离水呼吸，甚至能在湿地中爬行迁移。作为入侵物种引入北美后对本土生态系统造成严重破坏，被列为"100种最坏的入侵物种"之一。
Wikipedia
The northern snakehead is a species of snakehead fish native to temperate East Asia, in China, Russia, North Korea, and South Korea. Their natural range goes from the Amur River watershed in Siberia and Manchuria down to Hainan. It is an important food fish and one of the most cultivated in its native region, with 510,000 tonnes annual production worldwide. Due to this, the northern snakehead has been exported throughout the world and has managed to establish non-native populations in Central Asia and North America. In the United States, it is found in Pennsylvania, Virginia, West Virginia, Delaware, Maryland, North Carolina, Arkansas, Missouri, and Mississippi.
