I am sorry but I thought that heavy metal poisoning is due to eating fish that eats other fish, thus distilling the heavy metals in their own body. i.e. eating shark is worse that eating salmon. Is that not correct? I feel like the post above is completely misunderstanding the issue

Yeah, they're different issues, but similar causes. I can't remember the exact cycle, but essentially fish kibble in farms is made of small fish with heavy metals and farm fish that are fatty retain those metals in their fats to a much higher rate then other fishes. And it also ends up in dog food? It gets a little wild when your food chain is contaminated.

  Pesticides are cool. You're talking about bioaccumulation. Carnivorous species have a disadvantage. https://en.wikipedia.org/wiki/Bioaccumulation https://en.wikipedia.org/wiki/Bioaccumulation https://www.poisoningchildren.com/blog/2014/02/05/bioaccumulation-and-dead-baby-dolphins https://www.poisoningchildren.com/blog/2014/02/05/bioaccumul... "... because of the toxins dolphins accumulate in the oceans we have polluted, their uterine environment and breast milk are so toxic that it kills their first-borns. Later-born offspring have a better chance ..." "Children who breastfed were much more likely to get leukemia before the age of two when their mothers had been exposed to pesticides. And in turn, breastfeeding is one of the few measures that may provide women protection from breast cancer, possibly because the toxicants pass out of the breast fat with the milk"

    A simple solution to keep using pesticides and polluting the ocean may be switch human babies to formula, switch dolphin babies to human pumped milk, solving the cancer issues and the dolphin first-born problem except for the dolphin uterine environment which could possibly be fixed with cane toads.

      There is so much wrong in this comment. I'm not sure where to begin...

Tuna is really bad in this regard but also very popular in sushi.

Yes fish bioaccumulate heavy metals (mainly mercury) particularly tuna, still Much (an estimated 40%) of the mercury that eventually finds its way into fish originates with coal-burning power plants and chlorine production plants. https://en.wikipedia.org/wiki/Mercury_in_fish https://en.wikipedia.org/wiki/Mercury_in_fish
