I fully agree with your point, but especially for the specific example you've raised, I think there are some very difficult complications that arise from the (lack of an effective) current global governance model. For instance, regulations are mostly only effective if they're enforceable. With fishing taking place largely in international waters, and as I understand it, enforcement falling upon the coast-guard-equivalent of whichever country's flag the boat is flying, enforcement would be very difficult. As far as implementing better regulations, any single nation implementing the good regulations would effectively be putting their own industry at an economic disadvantage (and by extension, their citizens who must pay for the more limited supply) compared to the more lax nations. We see this with the global climate change debate too; basically every single nation needs to agree at the same time for global progress to be made. Edit: clarified the first sentence.
