Jul 14, 2022 | 10:36 AM

LETHBRIDGE, AB – The City of Lethbridge is inviting the community to learn more about invasive goldfish and koi found in local stormponds.

On Saturday, July 16 and Saturday, August 13, 2022 from 10:00 a.m. to 4:00 p.m., Firelight Pond will host the educational Goldfish Derby Days. The goal is to inform residents about the invasive species.

Firelight Pond is located at 64 Firelight Way West in Lethbridge.

Citizens who have a fishing license are invited to fish out goldfish and koi. Anyone who may not be a fan of fishing but is still interested in getting involved can enjoy family friendly activities and food trucks that will be on site. Educational materials will be posted around the pond, while members of the City of Lethbridge Parks, and Water and Waste Water departments will be available to answer any questions. Representatives from Alberta Environment will also be present.

In a news release, the City of Lethbridge stated that it “needs to eradicate goldfish and koi found in three storm ponds within Lethbridge: Firelight Pond, Chinook Lake and Elma Groves Pond.”

Officials noted that goldfish and koi are non-native species and can cause issues for the native species and habitat in stormponds, so, they must be removed “in order to create a balanced and healthy ecosystem.” The City of Lethbridge explained at aquatic invasive species (AIS) are non-native aquatic animals, plants or insects that have been brought in from other areas into Alberta’s waterways.

In the release, the City of Lethbridge stated, “AIS threaten and disrupt natural ecosystems and negatively impact biodiversity”.

Full removal of the goldfish and koi will take place at Firelight Pond in September and October.

Crews will use Rotenone, a naturally occurring complex that is non-hazardous to humans, pets and wildlife. It only affects gilled species.
