Species Collapse, Jack Mackerel


Jack mackerel "…is reduced to feed for aquaculture and pigs. It can take more than five kilograms, more than 11 pounds, of jack mackerel to raise a single kilogram of farmed salmon... Stocks have dropped from an estimated 30 million metric tons to less than a tenth of that in two decades. The world's largest trawlers, after depleting other oceans, now head south toward the edge of Antarctica to compete for what is left.”
