The 30%, as Boris said earlier, is a national goal. There's nothing that says that around Newfoundland specifically 30% of the waters would need to be closed to fishing.
I would argue, however, that the people of Newfoundland have been the first to experience a failure of fisheries management, which really should bring home to the people of Newfoundland that simply managing fisheries without the help of other methods that have been shown to be very effective elsewhere is perilous.
