Taking a Core Sample from a Chinook Salmon at Carson National Fish Hatchery, circa late 1970s-early 1980s

A man, dressed in coveralls, operating an apparatus that appears to consist of an electric drill mounted on a short metal pole, with an moveable metal arm. He is using the apparatus on a large fish (Chinook Salmon) that is placed on a wooden table in the center of the frame. In the background there appears to be a small wooden frame canopy.
