Goldfish Management Program
update - edgewater and ted hole stormwater facilities
In collaboration with Alberta Environment and Parks, the goldfish fish removal program was completed between September 25 and October 13. City of St. Albert staff completed the chemical treatment of Edgewater and Ted Hole Stormwater Facilities (SWF), using Rotenone, a naturally occurring compound derived from the roots of tropical plant. Rotenone is not harmful to humans, pets, wildlife or vegetation and breaks down naturally after application.
The City has collected a total of 1070 kilograms (2359 pounds) of Asian Goldfish from both SWF and the estimated population is between 30,000-40,000. Both SWF will be inspected in 2018 to evaluate the success of the program and if the fish are still present, treatment may need to be repeated in 2018.
In the fall of 2015, the City initiated a program to remove the goldfish from Edgewater Park storm water facility. The program consisted of drawing down the water level in the reservoir, electrofishing to remove some of the fish and using winter conditions to freeze the remaining water. Unfortunately, this management technique was unsuccessful and live invasive fish remain in the pond.
Since the Goldfish Management Program was intiated in Edgewater Park, two additional locations have been identified to have Asian Goldfish - Ted Hole Park and Lacombe Park Lake. The City will continue to collaborate with the province to identify approaches for removal of fish or mitigate the risks they present.
Don't let it loose
Asian Goldfish have been deemed as an invasive species and are a threat to the natural ecosystems and the operations of storm water systems. The City would like to advise that anyone who can no longer care for their domestic goldfish should speak to their local pet retailers or veterinarian about donating their fish to an aquarium or pond owner or learn about humane disposal. Information can be found at the Alberta Environment and Parks website. Releasing live fish into natural or man-made water bodies is illegal and can result in penalties.
Residents are not permitted to catch or remove any fish from a storm water facility. The removal of invasive species requires a special license from Provincial regulators to research, remove and eradicate the fish.
