This is an article I wrote for Curious Meerkat to celebrate World Oceans day 2014, asking the question "Is there such a thing as sustainable fish?"

The state of the world's oceans has shocked and worried me for years now, but as someone who eats virtually no fish at all, I've admittedly not put much effort into finding out about sustainable fish. Until now. Much of what I thought I knew was wrong - farmed fish, for example, is often worse than wild-caught - and I learnt a great deal more, as well. I hope this article may be useful for those who do eat fish but want to do so with minimal environmental cost. At least at the moment, that is a depressingly difficult (although not impossible!) task.
