It doesn't matter how many executive orders are passed, if these fishermen don't have any food to eat, these sharks are still going to be caught and sold. Giving them an alternative means of livelihood would be a good place to start. Executive orders are just ink on paper with no one to enforce them. We can't even guard our own coastline against foreign poachers, I doubt that we would have the resources to catch local fishermen. Usually, government officials just turn a blind eye, until it gets on the news.
