Using data from scientific stock assessments of trends in abundance and fishing mortality for stocks representing roughly half of global catch, we show that on average that stocks are increasing and fishing pressure declining. Merging these data with surveys of fisheries management systems we show that where stocks are intensively managed abundance is higher and fishing pressure lower than where there is little fisheries management. We conclude that the solution to sustaining global fisheries is to assess abundance, set regulations to adjust fishing pressure, and enforce those regulations. We do not have abundance data from half of the world’s fisheries, but surveys on management systems and expert opinion on stock abundance for those fisheries suggest the stocks are in poor shape.

(with Ulrike Hilborn) in 2019, “Overfishing: what everyone needs to know” (with Ulrike Hilborn) in 2012, “Quantitative fisheries stock assessment” with Carl Walters in 1992, and “The Ecological Detective: confronting models with data” with Marc Mangel, in 1997 and has published over 300 peer reviewed articles. He has received the Volvo Environmental Prize, the American Fisheries Societies Award of Excellence, The Ecological Society of America’s Sustainability Science Award, and the International Fisheries Science Prize. He is a Fellow of the Royal Society of Canada, the American Academy of Arts and Sciences, the Washington State Academy of Sciences, and the American Fisheries Society.
