If tuna is hatched and raised in non-mercury containing water, does that make it mercury-free?

Question

Will heavy metals travel from parent to offspring? If not, why aren’t fish that contain heavy metals hatched in places where water can be monitored?

In: Biology

Answer 1

Mercury accumulates through the food chain, so if it’s fed non-Mercury containing fish, it won’t accumulate it. Tuna can’t be farmed, they are wild caught.
