Marine Conservation

Marine Fisheries

The ocean's fish stocks are being devastated by unsustainable fishing practices. Today, bycatch, overfishing, and habitat destruction problems have depleted once bountiful fish populations and jeopardized the oceans' capacity for sustaining life.


Dolphin-Safe Tuna

The dolphin-safe label was originally adopted to stop the fishing industry's deadly practice of setting nets on dolphins to get at the tuna that swim below. Since the dolphin-safe label for tuna cans and pouches was created in 1990, dolphin deaths have dropped by 90 percent.


Mercury in Tuna

Defenders' ground-breaking study shows that the FDA and EPA's light canned tuna recommendations do not adequately protect the American public from high levels of mercury.
