If you think your fish is sustainable because it is farmed, think again.
Have you thought about what your farmed fish ate? You might have, after you read How did Chef Dan Barber fall in love with fish? . In his TED talk, Chef Barber spoke about the optimal fish feed. He didn't talk about the majority of fishmeal producers, who pulverize fish into a pulp to feed to their farmed fish -- that eat more and grow larger than in nature. For more information about fishmeal producers, watch this video: The Greed of Feed
In some cases, such as with Salmon, farmed fish is more sustainable -- as long as the fish farm is inland ( so that the fish cannot escape into the wild, as many coastal farmed fish do). If the location of the fish farm is unknown, buying fish that has been caught by long line fishing is optimal.
It is never okay to buy fish that has been caught by trawl ( dragging a net as big as football field along the ocean floor, collecting everything that gets in its way) or by gill-netting ( which is a giant curtain, capturing anything that tries to swim through).

The most important thing to remember is to eat in moderation. Have fish a maximum of once a week. Fish that are not endangered (yet) still risk being over fished. Cod, for example, has been overfished everywhere and so at the moment, the best source of cod is in Alaska, but that doesn't prevent overfishing there too. Take a break from all cod, salmon and tuna. There is no reason you cannot substitute fish for a more sustainable, environmentally friendly and equally nutritious alternative, such as hemp.

Here is a list of the most sustainable fish options:
Haddok - hook and line caught from Canadian Atlantic
Mackeral ( aka Cavalla, King, Kingfish, Smoker, Slab, Hog) - hook and line from Atlantic, Gulf of Mexico
Sablefish (aka Skilfish, Skil, Coalfish, Sable, Black cod, Gindara) - caught bottom longline in Alaska
Swordfish - caught by harpoon or handline in U.S. Atlantic, U.S. Pacific, Canadian Atlantic. Take note that it does have a high mercury content.
And for something a bit unusual, try Red Sea and Green Sea Urchin, dived for and gathered by hand. Red sea urchins are found in the Pacific Ocean from Baja, California up to Alaska. Green sea urchins live in both Atlantic and Pacific Oceans. Both types of urchin are prized for their roe. Urchin roe is popular in Japanese restaurants , sold under the Japanese name uni ( pictured below).
