The politicians and the majority of fishermen in the world appearantly don't know evolutionary theory very well because the way fish resources is generally managed with net fishing is completely stupid. When you have a certain mask size that only takes out fish above a certain size, you induce a selection pressure to become smaller; to become adult (capable of sexual reproduction) at a smaller size. So, many of the taxed fish species, like the cod we have here, are getting smaller and smaller. You may have heard of the fishing collapse in Newfoundland and heard that there's no cod there anymore. There are actually. They just don't grow big!
