Aquatic invasive species control at Leinweber park pond

Medicine Hat – In an effort to control aquatic invasive species in Leinweber pond, a qualified professional biologist will be administering a licensed pesticide this week. This pesticide will target the species without causing harm to the pond or other area species and wildlife.

“Goldfish and koi are non-native species and are considered to be invasive because of the adverse effects they can have in areas like retention ponds,” said Jeff Quinlan, Parks Technician with the City of Medicine Hat. “Invasive species like these goldfish have no natural predators and outcompete any other species in the area, creating an unbalanced and unhealthy ecosystem.”

Aquatic invasive species include non-native aquatic animals, plants or insects which have been brought into our ponds and waterways and negatively impact biodiversity.

If you are no longer able to care for a fish in your aquarium or pond, the Government of Alberta recommends:

• Contacting a retailer or pet store
• Giving it to an aquarium or pond owner
• Donating to a school
• Talking to a veterinarian

“The goldfish and koi have taken over this pond and have been causing problems for years. This is a costly mitigation effort and requires several treatments to be considered effective,” said Dave Genio, Manager of Parks with the City of Medicine Hat. “We want the community to continue enjoying these neighbourhood ponds. Please don’t release any fish into our ponds, storm or sewage systems.”

Leinweber park remains closed due to the ongoing construction to replace irrigation lines and transition the park to alternative landscaping. Please follow all area signs and allow contractors room to work safely.

The City of Medicine Hat thanks residents and park visitors for their patience and understanding.
