Mercury levels in popular fish — including tuna, salmon and swordfish — are rising, and climate change and overfishing may be to blame, a new study suggests.
Warmer water appears to be one of those contributing factors, the researchers reported Wednesday in Nature.
Because the Maine waters have been overfished, cod and dogfish were forced to change the types of prey they consumed. Cod ended up devouring more lobsters and other large invertebrates, which are low in mercury, while the dogfish went for more squid and other cephalopods, which tend to be high in mercury. Unsurprisingly, the cod ended up with lower mercury levels than the dogfish.
The oceans were warming. And as a result, the fish were becoming more active, Schartup said. “Because of that, they needed more energy to move, so they ate more,” she added.
