A method recently described by W. E. Ricker for determining the size at which fish should be taken to provide maximum sustained yield, is applied to a commercial fresh‐water fishery. This method indicates that maximum sustained value to the fishermen would be provided by any gill‐net mesh size (stretch measure) between 3 inches and 3 3/4 inches inclusive. Over this range there is no clear‐cut advantage to any particular mesh, although there is probably a slight advantage in one of the smaller meshes.
