HIGH RIVER, Alta. — There’s something fishy about the storm water ponds in a town in southern Alberta.

The town of High River says anywhere between 35 and 100 domestic goldfish have been spotted in the forebays of the storm pond system of Highwood Lake.

The town is asking people who can no longer care for their fish to contact pet shops or veterinarians.

Senior fish biologist Craig Mushens, who’s working with the town to fix the problem, says the fish are an invasive species.

The goldfish are also known as Prussian carp, and Mushens says they out-compete native species for food and habitat and spread diseases, as well as spread from one body of water to another.

Releasing live fish into Alberta water bodies is illegal and the fines can be as high as $100,000.
