Ecosystem-based fisheries management (EBFM) has been applied in Alaska for decades with great success. Alaska’s valuable commercial fisheries are among the most productive and sustainable in the world. However, current EBFM policies were not designed to address climate change.
A new study evaluates the future performance of EBFM in the eastern Bering Sea. The innovative experiment projects that EBFM can forestall climate-driven collapse of key Alaska fisheries better than other management policies. This management approach considers the impacts on fish stock productivity from environmental variables, such as changing ocean conditions, and socio-economic factors. It can help fishery managers and fishermen in planning for the future.
“Ecosystem-based management doesn’t just help fish, it helps fishing communities. It is the best strategy we have to provide harvest stability in the coming years. It buys time for Alaska fisheries and fishing communities to prepare and adapt. EBFM is going to be a vital tool for us under climate change,” said Kirstin Holsman, biologist at NOAA Fisheries’ Alaska Fisheries Science Center. “But no matter how effective management is, by mid-century—maybe sooner—Alaska fisheries may reach a tipping point of rapid decline in the eastern Bering Sea if climate change continues on the current trajectory and fish and fisheries are not able to adapt to these changing conditions. To guarantee long-term success, we need to couple EBFM with global climate change mitigation.”
