The Gulf of Maine northern shrimp (Pandalus borealis) supports an important fishery in Maine. Since 2010, however, the stock has declined precipitously, with the fishery being closed each year since 2013. It is believed that changes in shrimp habitat due to climate change as well as high fishing pressure are to blame for declining populations.

Understanding how warming temperatures affect northern shrimp distribution can inform future management of the fishery. Using climate model data from the Fifth Assessment of the Intergovernmental Panel on Climate Change, as well as shrimp sampling data from Maine Department of Marine Resources (DMR) ocean sampling trips, Thompson will simulate changes in the marine environment and resulting changes in the distribution of shrimp. DMR plans to use the results to explore alternative strategies of managing the fishery, given projected changes in shrimp abundance and distribution. Sea Grant funds are supporting the purchase of temperature and depth loggers for deployment during DMR’s 2016 shrimp sampling season.
