July 9, 2018 — One in three fish caught around the world never makes it to the plate, either being thrown back overboard or rotting before it can be eaten, according to the UN Food and Agriculture Organization.
Its biannual report on the state of the world’s fisheries, released on Monday, also shows that total fish production has reached a record high thanks to more fish farming, particularly in China, with over half the fish eaten in the world now coming from aquaculture.
In contrast, the amount of wild caught fish has barely changed since the late 1980s and a third of commercial fish species are overfished, the FAO says. Fish farms will continue to expand and the FAO projects that almost 20% more fish will be eaten by 2030, helping sustain the growing global population. However, farmed fish can harm wild populations because often their feed, made from wild fish such as sardines and anchovies, is caught at sea and they can cause pollution.
Fish are a crucial source of nutrition for billions of people around the globe, but overfishing is rife in some regions, with two-thirds of species overexploited in the Mediterranean and Black Seas and the Southeast Pacific. Previous analyses that include estimates for illegal fishing indicate that wild fish stocks are declining faster than FAO data suggest and that half the world’s oceans are now industrially fished.
