Wild Alaskan Salmon because Alaska’s salmon fisheries have a strong management system that keeps habitats (where the fish spawn) very clean.
Not This:
Non-U.S. farmed salmon because it tends to be raised in open pens in coastal waters, into which harmful waste – plus parasites and diseases-can get directly released.
Buy This:
U.S. shrimp wild or farmed is OK because shrimp farms in the U.S. have fairly eco-friendly practices and bycatch (other sealife caught in nets) is rare with American wild-caught shrimp.
Not This:
Imported shrimp, because its often from Asian or Mexican farms that are not tightly regulated and disrupt local ecosystems. One environmentally friendly exception: shrimp from farms in Thailand.
Buy This:
Troll or pole caught Tuna because fishermen use a pole and bait instead of longlines which have hundreds or thousands of baited hooks on them, to avoid catching innocent nearby sea life.
Not This:
Any tuna not labeled, “troll-or-pole caught”, because the typical longline endangers sharks and turtles. Bluefin tuna is a very endangered species and is another type to avoid completely.
