Dr. Malin Pinsky: Changing ocean temps and what they mean for fish and people

WASHINGTON (Saving Seafood) — January 17, 2018 — Last Thursday, Dr. Malin Pinsky, a professor of ecology, evolution and natural resources at Rutgers University, gave a Bevan Series lecture on how fish have adapted to changing ocean temperatures, and the implications for fisheries and people. “Fish and Fisheries in Hot Water: (How) Do We Adapt?” was the second of ten planned lectures in the 2018 Bevan Series, which features experts discussing fishery and marine conservation issues. The series is hosted at the University of Washington in Seattle.

A description of Dr. Pinsky’s lecture is below:

The same ecological and evolutionary processes operate in marine and terrestrial environments, and yet ocean life thrives in a fluid environment that is dramatically different from what we experience in air. The ocean is, in effect, a 1.3 sextillion liter water bath with muted thermal variation through time and space and limited oxygen. In this talk, I will trace what I see as some of the important consequences for fish and fisheries, including a number of striking contrasts and similarities to patterns on land. Most marine animals have evolved narrow thermal tolerances and live close to their upper thermal limits, which makes them surprisingly sensitive to even small changes in temperature. I will show that fish and other marine animals have responded rapidly and often quite predictably to temperature change and temperature trends, across time-scales from seasons to decades. Finally, I will link these rapid ocean changes to their impacts on fisheries and on people. The tight feedbacks and lagged responses between fisheries and ocean dynamics create both immediate impacts and complex dynamics that can complicate management efforts. The magnitude and extent of climate impacts on fisheries imply the need for a new era of climate-ready management more fully informed by environmental dynamics and long-term trends.

Malin Pinsky, Ph.D., is an Assistant Professor in the Department of Ecology, Evolution, and Natural Resources and an Alfred P. Sloan Fellow in Ocean Sciences at Rutgers University. There, he leads a research group studying the ecology and evolution of global change in the ocean, including conservation and management solutions. He developed and maintains the OceanAdapt website to document shifting ocean animals in North America, a resource used by governments and NGOs for climate adaptation planning. He has published articles in Science, Proceedings of the National Academy of Sciences, Current Biology, and other international journal, and his research has received extensive coverage in the press, including the New York Times, Wall Street Journal, BBC, CBC, and National Public Radio. He has received early career awards and fellowships from the National Academy of Sciences, American Society of Naturalists, and the International Council for the Exploration of the Sea. Previously, he was a David H. Smith Conservation Research Fellow at Princeton University. He has a Ph.D. from Stanford University, an A.B. from Williams College, and roots along the coast of Maine.

 

Dr. Ray Hilborn talks U.S. fisheries policy at Bevan Series lecture

WASHINGTON (Saving Seafood) – January 8, 2018 – Last week, Dr. Ray Hilborn, a professor at the University of Washington’s School of Aquatic and Fishery Sciences, presented on U.S. fisheries policy and how scientists can communicate with Congress to promote good decision-making. The lecture, “Is U.S. Fisheries Policy Working? Getting the Message to Congress,” was the first of the 2018 Bevan Series on fisheries management.

The Bevan Series features “internationally recognized experts” discussing current issues facing fisheries and marine conservation. This year’s series features 10 weekly seminars held at the University of Washington in Seattle.

A description of Dr. Hilborn’s lecture is below:

The Magnuson-Stevens Fisheries Management and Conservation Act of 1976 is the primary piece of federal legislation governing fisheries whose objectives include: exploring, exploiting, conserving, and managing all fish within the exclusive economic zone; to promote domestic commercial and recreational fishing under sound conservation and management principles; to provide for the preparation and implementation, in accordance with national standards, of fishery management plans which will achieve and maintain, on a continuing basis, the optimum yield from each fishery; to encourage the development by the United States fishing industry of fisheries which are currently underutilized or not utilized by United States fishermen. Optimum yield is defined the yield from a fishery, means the amount of fish which will provide the greatest overall benefit to the Nation, particularly with respect to food production and recreational opportunities, and taking into account the protection of marine ecosystems.

This talk will focus on how the U.S. is doing with respect to these objectives, and my perspective on how scientists can let Congress know how well we are doing, and help Congress make good decisions. I will discuss the success at rebuilding fish stocks and protection of marine ecosystems, a mix of success and failure at producing benefits to food production, and recreational fishing opportunities.  I will discuss my limited experiences at communicating with Congress through invited testimony to House and Senate committee hearings over 25 years, and two separate briefings of Congressional staff.

Ray Hilborn is a Professor in the School of Aquatic and Fishery Sciences, University of Washington specializing in natural resource management and conservation.  He authored several books including 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. He has also published over 300 peer reviewed articles and served on the Editorial Boards of numerous journals, including seven years on the Board of Reviewing Editors of Science Magazine. 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 American Fisheries Society, the Washington State Academy of Sciences, the Royal Society of Canada and the American Academy of Arts and Sciences.
