Prussian Carp
Carassius gibelio
The Prussian carp is an established invader in Alberta — now common in the lower Bow River and irrigation canals, and spreading in southern Saskatchewan. It is constantly mistaken for crucian carp and goldfish by Alberta anglers. Under Alberta rules it must NOT be returned alive: do not release it, never move live fish, and check current provincial rules.
