Personally, I’m a huge oyster fan. If you’re lucky you can find some good little seafood joints with reasonable prices. Additionally, rainbow or steelhead trout are amazing options as well. I’m not sure how they compare to price in terms of typical salmon, as these guys are technically salmonoids as well. What I will say though, is that if you’re a salmon guy, I think you might even prefer trout. It is seriously mindblowing imho.
Also, on the canned fish note, I might be a little cautious just because inside the tins, there are thin layers of plastic that DO leach into canned foods generally speaking and are therefore estrogenic. On occasion, this might be an option, but if you’re looking to optimize your health, I don’t really think it’s a daily option. Just something to consider. If you wanna learn more, Id recommend you read Estrogenics by Dr. Anthony Jay.
Best of luck pal.
