When you consider that equal a quarter of the world catch, you begin to see the sides of the problem. In some parts of the world, for every kilogram of prawns caught, up to 15 kilograms of unsuspecting fish and other marine wildlife die, simply for being in the wrong place at the wrong time. True, some countries are beginning to deal with this problem, but it is vital we find rational ways of fishing, before every ocean becomes a dead sea. It would make sense to give the fish enough time to recover, grow to full sizes and reproduce, then catch them in a way that doesn't kill other innocent sea life.
