UMATILLA NATIONAL FOREST, Ore. (AP) – Oregon wildlife officials are trying to remove goldfish and other invasive fish that have been introduced to ponds in the Umatilla National Forest.
The East Oregonian reports that the Oregon Department of Fish and Wildlife treated two ponds Wednesday to remove schools of goldfish and bullhead catfish that have been illegally introduced to the water.
Crews put a plant-based poison into the ponds that kills all fish in the water, including uncaught trout. Wildlife officials stock the ponds with rainbow trout for anglers.
Wildlife officials say the goldfish and catfish increased competition for food and space, stunting the fishery. By poisoning the ponds they must restart the fisheries.
Nine other ponds across northeast Oregon will also be treated. The ponds will be restocked and ready to fish by spring.
