Fishing and climate change: two of the largest human impacts on the ocean. But how do they interact? In a new paper just out in Ecosphere, Emma Fuller, Eleanor Brush, and I use an ecological model to build some intuition. We looked specifically at how fishing affects the ability of species to shift their distributions fast enough to keep up with climate velocity. Two main take-home messages:
Fishing the leading edge of a species range has the biggest impact (this also tends to be where fishing is unregulated….)
Marine protected areas (MPAs) can actually make it harder for species to keep up with climate if the MPAs concentrate fishing effort in narrower areas.
We host a monthly seminar series on climate and fish, which call “Fish Baste,” designed to increase dialogue and collaboration among members of Rutgers, Princeton, U. Maine, and NOAA, as well as among researchers in ecology, social science, and climate science. Format is a short, informal talk, followed by discussion, and meetings are open to anyone.
New schedule for the year is filling up, and it looks great!
The news about the Coastal SEES awards is now official: http://www.nsf.gov/news/news_summ.jsp?cntn_id=132637. We’re excited to get started on the collaboration with Kevin St. Martin, Eli Fenichel, Simon Levin, and Bonnie McCay! We’ll be focused on adaptation of fish and fisheries to rapid climate velocities.
Nature Climate Change ran a feature story on Mike Fogarty and Malin’s earlier paper in Climatic Change Letters. To quote the story: “Adaptation to climate change in fisheries is occurring very rapidly. Research now shows that it is a complex process whose outcomes can both mitigate and exacerbate impacts on fish populations.” How people respond and the coping responses they use are an important part of the story.
It is increasingly clear that marine fish are shifting and will continue to shift poleward as climates warm. However, what these shifts mean for fisheries has long been less clear. In a new paper in Climatic Change, Mike Fogarty and Malin show how fisheries and the value of their landed catch are also moving poleward (see graph on right for four species in the northeast U.S.). These shifts push some species out of reach for coastal communities, but also provide new opportunities. This kind of information can inform decisions about how to adapt to climate change, but such adaptations take time and have costs. Local knowledge and equipment, for example, are geared to the species that have long been present in the area.
