The Hupa, like many tribes in the area, fished for salmon in the Klamath and Trinity rivers. One of the methods they used to capture fish was the fish weir, which tribal members would maintain. A fisherman stands on each of several platforms erected below an equal number of openings in the weir and lowers and draws his dip-net at random. As the construction of a weir is a communal undertaking, the catch is divided each evening according to the requirements of the various families.
