The Aust. Marine Conservation Society has released an online version of its “sustainable seafood guide” which allows you to search their database to find out if your favourite seafood is sustainably caught/farmed – you can get it to list all the things we’re sustainably allowed to eat (which is a pretty short list) by selecting “Better Choice” from the Classification box.
