The few that were at least able to swim halfway. They loaded them on to trucks, headed to this hatchery. Having to go to the emergency trap and haul was not an ideal situation. Reporter jeff heindel is a coordinator with idaho fish and game. Id rather have them in the river swimming on their own, but in terms of species preservation,un, its a necessary evil.
