Nobody seems to have mentioned mercury yet. As larger fish eat smaller ones, the levels of mercury in the big guys start to compound. Mercury can damage your brain and other organs. The tuna I happen to like best is Natural Catch, which I bought via a FB ad. Definitely not albacore, which is high in mercury, not to mention too dry unless packed in oil or you doctor it a lot! Natural Catch is pole and line caught - yellowfin if memory serves. They are smaller size fish, under 15ppm mercury. Now, whether or not catching the young’uns threatens the species survival at this point, I know not. This brand comes in 4-oz pull-top cans, in a mix of olive oil and vegetable broth that is so delicious that I’ve never gotten so far as making a sandwich. I am not the only to confess that I slurp off the liquid, then eat the petite fillets with a fork, straight from the can. There are 12 cans per case, usually about $3 per can , shipping free. I see that they now have sardines too, and sometimes water packed and albacore.
I keep buying celery with the intention of using it for tuna salad with Kewpie, pickle relish, and a 1:1 ratio of Natural Catch to ordinary supermarket tuna…an a couple of weeks later, tossing out the limp, unused stalk.
