Deep-Sea Fish Mutations

Guest: Michael Kent, a professor in the Department of Fisheries and Wildlife at Oregon State University. His study on the effects of toxicants on mile-deep ocean fish was published in the journal the Marine Environmental Research Even if they don’t live close to the shore, fish can’t escape the consequences of human pollution. Scientists have recently discovered that deep-sea fish in the Bay of Biscay, west of France, have developed odd mutations from the poisons and metals that accumulate there. The findings are troubling both for the fish and the humans who could be harmed by eating them.
