How can a fishermen make more money? By catching fewer fish.
That happy lesson is well known in the waters of Australia, as I discovered when I visited the lobster and tuna fisheries there for a New York Times Magazine article. But now there’s even better news, for both fish and fishermen, in an Australian study published today in Science. It turns out that profit-seeking fishermen should want to catch even fewer fish than the “sustainable” number calculated by biologists, because leaving more fish in the ocean leads to bigger populations that make for easier and more lucrative fishing in the long run.
