Good point, but it's a little different. It works well for fish with well-defined fisheries in territorial waters, but it doesn't work for open ocean species. B

Good point, but it's a little different. It works well for fish with well-defined fisheries in territorial waters, but it doesn't work for open ocean species. Bluefin tuna in particular is an example. They often cross oceans to get to breeding grounds, and that water is totally unregulated. It can be fished without regulation or reprisal.
