A new paper out in Marine Policy ($) gorgeously illustrates global fisheries over the past 150 years. The figures tell the story and are cool as hell (spoiler—we saved the best for last):
How much fish has been caught annually?
The surge in landings after 1950 is mostly due to the fact that the United Nations Food and Agriculture Organization (FAO) started recording landings then; catches before 1950 were probably much higher than indicated in the figure, but data is sparse.
Global reported catch has been hovering around 80 million metric tons for the past 30+ years, with proportional amounts of discards and illegal, unreported, and unregulated (IUU) fishing.
Industrial fishing vs non-industrial
Non-industrial fishing includes subsistence, recreational, and some small-scale fishing.
All fishing since 1950s
What kind of fish is caught?
Much of the small pelagic fish like sardines and anchovy are turned into fishmeal to feed livestock and farmed fish. Demersal fish are fish that live near the bottom of the ocean like cod.
How is fish caught?
Who is catching the fish?
This figure shows the emergence of Asia as a major player in global fisheries.
Where is fish caught?
This is one of the coolest figures we’ve ever seen. You can see that areas with lower catch (like the high seas) correlate to areas with lower primary productivity—we go into further detail about primary productivity and fisheries here, in Seafood 101. A few weeks ago a different paper was published in Science that mapped the “footprint” of fisheries, essentially showing where fishing boats travel in the ocean. The paper was criticized for failing to show what the above figure shows clearly: how much fish is caught where. This is the true map of global fisheries.
The dataset used to create all these figures and maps are available to the public here.
