Enter the super predator.<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n

Across the world, humans have overwhelmed wild populations and brought chaos to natural ecosystems. We may suspect this intuitively, but now researchers have some hard numbers to show just how efficient humans are as predators.<\/div>\n

The result of a decade of work, new research shows<\/a>\u00a0that the typical marine fishery kills adult fish at 14 times the typical rate of a wild predator. Humans tend to hit fisheries harder\u2014with hands, hooks, and nets\u2014than any other group of wild animals.<\/p>\n

Even the better managed fisheries often start with the proposition of harvesting as much as possible. \u201cThat\u2019s the general paradigm,\u201d says\u00a0Chris Darimont<\/a>, a Hakai Institute-Raincoast Conservation Society scholar at the University of Victoria. \u201cHow can we maximize the so called sustainable yield to humanity?\u201d<\/p>\n

Drawing on existing data, Darimont compared the predation rates of human versus wild predators. For example, in Alaska\u2019s Kodiak Archipelago, grizzly bears catch six percent of the adult salmon, while humans catch 78 percent, or 13 times more fish.\u00a0Given the numbers, he says, humanity\u2019s toll on ocean species is alarming and underlies many of the problems observed in the oceans today.<\/p>\n

\u201cEveryone assumes we are this dominant predator, but until now we didn\u2019t know how to describe it,\u201d he says. \u201cThose cross-ecosystem comparisons had never been done before. It provides details at a global scale.\u201d (Darimont\u2019s research is supported by a grant from the Tula Foundation, which also funds\u00a0<\/em>Hakai Magazine.\u00a0The magazine is editorially independent of the institute and foundation.)<\/em><\/p>\n

Mechanized fishing methods, global seafood markets, and industrial processing\u2014combined with relatively high reproduction rates among fish\u00a0and their schooling behavior\u2014may help to explain the high take in fisheries, says Darimont.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
