Okay yeah, those are the ones I'm familiar with. That's all livestock studies. I haven't seen one about fish.

We could possibly extrapolate from there, but the biome of the human body is so vastly different than sea creatures that it may not apply.

Could you err on the side of caution? Sure. But if you're not wealthy and have to choose between farmed protein sources or no protein sources? Eat what you can afford. And don't fear monger people to the point where they make poor health choices due to their budget.
