Alaska Department of Fish and Game biologist Jay Baumer said a plan to use pesticides in Cuddy Pond to eliminate goldfish has been successful. Biologists applied the plant-based chemical rotenone last Wednesday. Since then, Baumer said, Fish and Game workers have scooped up about 150 large fish — between five and eight inches long — as well as 10,000 smaller fish from the pond.

Biologists have collected thousands of goldfish since applying a pesticide to Cuddy Pond a week ago

Baumer said they believe the chemical was applied just in time since the goldfish were clearly reproducing in the pond. He thinks they were able to kill the fish before they escaped into the waters of Fish Creek, which is connected to Cuddy Pond, although they plan to continue monitoring the situation. He said the water is safe now and should be completely clear of chemicals by the weekend.

Goldfish are an invasive species in Alaska

Goldfish are an invasive species in Alaska that competes with native fish and can spread disease. Fish and Game still isn't sure how they ended up in Cuddy Pond, but Baumer asked that people report it if they see any more, along with other invasive species.

Baumer said the message continues to be the same: don't release pets into the wild or dump your aquarium into local lakes in an attempt to find them new homes.

The Invasive Species line is 1-877-INVASIV.
