SALIDA – Colorado Parks and Wildlife is working to combat disease in the Arkansas River.
Officers and volunteers were out Wednesday at the Mount Ouray Fish Hatchery in Salida snipping pelvic fins from 20,000 rainbow trout before they are stocked in the river.
CPW said the fins are snipped as part of research to combat whirling disease.
These particular trout have been bred to hopefully be resistant to the disease.
With their fins snipped, the fish will be identifiable when researchers go back to check on the health of the fish.
