Climate change adds uncertainty to fisheries management

A new analysis of fisheries management concludes that climate change will significantly increase the variability of the size and location of many fish populations, creating uncertainty for fisheries managers – and the need for greater flexibility.

Most management processes are slow and cumbersome, as well as rigid, the authors say, and don’t adequately take climate change and human behavior into account.

“What climate change will do is pit the increased resource variability against the rigidity of the process,” said Susan Hanna, a fishery economist from Oregon State University and co-author of the report.

“Over time, managers will have to become more conservative to account for the greater uncertainty, and we will need to do a better job of understanding the effect of uncertainty on human behavior,” said Hanna, a long-time Oregon Sea Grant economics specialist.
