Those are sockeye salmon at the mature stage of their life. They are also called "red salmon".

Edit: I reread your comment and now understand that you are talking abt the color, not the fish. My bad.

Wow, both of you taught me some neat stuff! Astaxanthin sounds like it plays multiple roles in the lifecycle of salmon and is one of the most powerful antioxidants as well, so it benefits those of us that eat salmon. It's also the same reason/process that makes flamingos their beautiful color.

A potential "no stupid questions"-question.

Will I turn pink if I eat enough Astaxanthin? Is it toxic in the amounts that would be necessary?

Salmon is my number 1 food i want scientists to start growing in labs, cheaply and without animal harm.

We are far off still but i am rooting.

I don't know if it's placebo, but I think I notice a difference in flavor between wild-caught and farm-raised salmon. I guess it's like beef from cows that are raised with care versus beef from those that aren't?

Would you believe those sick bastards raise the salmon IN dihydrogen monoxide?

Eat what you can afford.

Is the real take away but I can pretty much always taste the difference between farmed and caught fish because their diet and exercise isn't the same. And no, I'm not talking about the freshness quality, that's just universally ass in the USA because we import fish from across the globe.

But the global demand for seafood is so damn high that I'd rather put up with farmed fish than nuking the entire ocean.

My main issue is diet source and water filtration. (most) Fish evolved to basically not spend energy mitigating toxins and other heavy metals in their bodies because they're used to living in a constant stream of water, hence why they generate ammonia instead of urea, because the sheer volume of water will dillute it away.

Both wild and farmed fish are highly susceptible to polluted food and water, which we really do not take enough care of these days lol.

I thought the problem was damage to the environment rather than any health risks for eating it.

Although I think most of those problems could be solved and it is just cheaper not to bother.

Nah it can also be fully synthetic, but it's the same thing, it's just preferred carotenoid for them

Farmed fish is still fuckin awful for you (and the environment) compared to wild fish
