The principal tool for evaluating biomass and, hence, exploitation rate for Atlantic snow crab, Chionoecetes opilio , has been the Leslie method which is based on commercial catch rate and cumulative catch through the fishing season. The method assumes a closed, homogeneous stock. However, a snow crab stock is often not closed because recruitment can occur during the fishing season as crabs molt into legal size. Also, stocks are not homogeneous. A dynamic simulation of fishing/searching on a heterogeneous sessile stock with within-season recruitment was developed, based on the Cape Breton fishery, to assess the robustness of the Leslie method.
