Wildlife officials survey Animas River fish in wake of Gold King Mine spill

Jim White, an aquatic biologist with Colorado Parks and Wildlife, walks a raft through the shallow Animas River, as Pete Deren, an aquatic tech, operates an anode used to shock the fish, and Mike Japhet, a retired aquatic biologist, nets a fish Tuesday during a survey of the river’s fish population.
