No, I see that point.
I guess what troubles me somewhat, and correct me if I'm wrong, is that I don't get a sense that anybody, whether it be the fishermen or the fisheries managers, really have a sense of what the biomass is out there. We know what we catch and we know what we maybe put back—if we happen to catch them—and so on, but do we know enough of what the biomass is. If we don't know that, we really don't know what the exploitation rate is. Am I wrong on that?
