Clipping fins off fish

Black and white photo of a woman in waders and a long-sleeved work shirt with sleeves rolled up, standing at a concrete trough filled with water and divided with metal screens into compartments. She holds a fish longer than her hand in her mesh-gloved left hand and is in the act of snipping off a fin on the fish. Cut-off fins are scattered in the water and on the edges of the trough. A rectangular net is propped across the compartment she leans over, containing 4 more fish.

To mark hatchery fish, fins are often clipped. This was done by hand in the past, offering seasonal work to women as well as men.
