Wildlife officials drop fish out of airplanes in Utah

The video discusses the method of restocking remote mountain lakes by dropping small fish from airplanes. These fish, typically 3 to 7 centimeters long, are used to replenish over 200 lakes annually. Officials claim a 95% survival rate due to the fish's small size. Historically, fish were transported using milk cans and animals like horses to reach remote areas.
