We analyzed past management performance in the Fraser River sockeye salmon fishery, examining how much more profitable the fishery could have been under different harvest rules than those that were applied historically. There has been uncertainty about what management regime would be optimal because of (1) large cycles in the abundance of the stocks, the cause(s) of which are unknown, and (2) past underestimates of the capacity of the ecosystem to produce sockeye. We used historical stock-recruitment data and variation in productivity as the basis for retrospective biological dynamics using two different biological models, each model corresponding to a hypothesized...</br>
