This $20 billion would be about 25% of landed value globally. When we did a study of deep sea fisheries and the subsidies that go to them, we did a calculation of their profits and it came out to about 10% and the subsidy is about 25%. This is why economists are quite concerned about this. A lot of the activity that leads to overfishing and all that is actually fuelled by these subsidies.
