數月前因暴雨及水電站大壩洩洪,湖北清江有漁民的魚網被沖走,近萬噸大型肉食性黑龍江鱘、西伯利亞鱘、施氏鱘及雜交鱘等擴散長江,而這些外來物種會對長江的生態造成災難性影響。牠們會直接捕食其他魚類,也有機會與近親白鱘、中華鱘和達氏鱘交配,對已極危的中華鱘增添另一威脅。

floodwater destroyed fish farms in Hubei province, 10,000 of tonnes of non-native sturgeons including Amur, Kaluga and Siberian sturgeon are washed into Yangtze River. this created disastrous ecological impact. these non-native sturgeons might breed with other native sturgeons, and creating more threats to the critically endangered Chinese sturgeon.
