   crabs (Chionoecetes opillio) in St. Mary's Bay, Newfoundland, before and after the fishery, and to ... for fisheries studies. We also show how to combine the two approaches in a single estimator. It is ... necessary to sample the population before and after the fishery, and to determine the total harvest and its ... composition, in order to use these methods. We use the methods to estimate the population of legal-size snow ...
