That has been a problem in the past. There's nothing in terms of UNCLOS that would prevent somebody from coming forward and fishing in the NAFO regulatory area, as long as they're cooperating with the organization.
Having said that, the presence of NCPs, non-contracting parties, has dropped dramatically over the years as a result of actions taken by Canada, and recently by NAFO and NEAFC, and by Iceland as well. I'm not quite sure if anybody has data on that. I don't think we've had much in the way of presence of those kinds of vessels in recent years. But it is not prohibited under UNCLOS.
