I did know at the back of my mind that, of the fish species I can choose to cook for dinner, some are better choices than others ; but I really didn't know which fillet was a better choice for sustainability than the next one. Luckily The Royal Forest and Bird Protection Society of New Zealand does know and has prepared the Best Fish Guide.
The Best Fish Guide lists the fish species available in New Zealand in best choice to worst choice order. Unfortunately no fisheries are actually good choices.
I had bought a selection of fish with which to make a fish soup just before I discovered the guide. I am sad to say that two of the five species I chose were in the Red Worst Choice list : snapper and groper. But the other three were in the Amber Concerns list : trevally, tarakihi and gurnard. I do not think that I will be buying snapper or groper for a long time. It is easy to live without knowing these things but once you find out, and the more you learn, the harder it is to ignore.
Here are links to similar resources around the world, as found on the links page on the Best Fish Guide website :

Problem is the deeper sea fish like snapper are cleaner fish and supposedly healthier for us than the species recommended as first choices.
Interesting . . . the more you learn the more you learn. So is it that the deeper the fish the worse, in terms of sustainability, but the better in terms of health?
It seems that way Emma. I think it is something to do with the more sustainable fish being bottam feeders in shallow waters. This is according to my Chinese friend, owner of IE Produce in Auckland.
My future father in law is a government oceanography guy, in charge of setting fishing quotas, and he refuses to eat any fish that has a life cycle of longer than 4 years. This is based on the theory that fish accumulate so many toxins from the ocean, and buying a small fish doesn't necessarily guarantee it is a young one. So he basically will only eat certain types of salmon.
