Tuna Fishing Ban, another 'muscle-flexing' of the Big Countries?

The ban on fishing tuna would greatly affect the livelihood of thousands of people depending on these fishes. Governments of small countries like the Philippines, FS of Micronesia, Vanuatu, etc. would have nowhere to go but to 'bow' their heads again and just make a sigh on orders by these large, rich nations to stop the fishing of tuna for 2-years. What now for these small fishermen/traders?
