Overfishing—taking fish and other sea creatures from the ocean faster than they can reproduce—has caused more change to the world’s oceans than any other single factor so far. From fish to whales, overfishing has depleted many populations of ocean animals. Some have collapsed to very low numbers. Some are no longer commercially viable.
A related problem is illegal fishing. Some fishermen, desperate to make a profit, catch more than they are supposed to, fish in areas they aren’t supposed to fish, and do not report their catches. They steal fish from the ocean. Scientists estimate that at least one fifth of the world’s catch is caught illegally. Illegal fishing harms some of the ocean’s most vulnerable ocean wildlife, like sharks, bluefin tuna, and Chilean seabass, undermines efforts to rebuild depleted species, and takes profits away from honest fishermen.
What You Can Do
See the “Fisheries Management” issue to learn about what we can do to protect fish populations from overfishing and illegal fishing. And check out our Healthy Oceans Seafood Guide to find out which fish are fished sustainably. Our seafood assessments consider whether fishing is occurring at an appropriate level, given the species’ abundance, as one of its four core criteria.
