Province reminds Albertans not to release pet fish into waterways as goldfish threaten ecosystems

The Government of Alberta is reminding residents that pet fish do not belong in storm ponds or waterways as part of its "Don't Let It Loose" campaign.

On July 20, Alberta Environment and Protected Areas issued the warning, highlighting the ecological damage caused by invasive aquatic species. "Goldfish belong in aquariums, not in Alberta's waters," said Grant Hunter, minister of environment and protected areas. "Don't let it loose."

Goldfish and other invasive fish pose major risks if introduced into native ecosystems. They can adapt to different conditions, outcompete other fish for food, destroy aquatic plants, degrade water quality, and introduce diseases or parasites into the environment.

According to estimates, one released goldfish can produce 40,000 offspring in three years. Preventing those species from being released is the most effective way to limit their spread.

Sightings of invasive fish can be reported to the Aquatic Invasive Species Hotline at 1-855-336-BOAT (2628). If possible, a clear photo showing the fish's entire body and fins is helpful for follow-up.

It is illegal to move live fish from one waterbody to another, which can result in a $100,000 fine and up to one year in prison. Anyone who witnesses the suspected intentional release of an aquatic invasive species can call the Report-A-Poacher hotline toll-free at 1-800-642-3800.

In Okotoks, thousands of goldfish were removed from storm water ponds in Crystal Ridge and Drake Landing about 10 years ago. The fish were thought to be pets released into the ponds. The Town of Okotoks said parks services has no recent reports of invasive goldfish.
