Fishermen's experience-derived "local ecological knowledge" can be equally valuable as data gained through modern scientific methods for informing resource management and building community resilience. Yet the very experience that forms the basis for fishermen's knowledge is being eroded by increasing specialization in Maine's fisheries, with more harvesters focusing on one or two target species. As fishermen focus on fewer types of fish, they have less access to the environment. Does this mean they are losing environmental knowledge, too?

Joshua Stoll, University of Maine assistant research professor of marine policy and cooperating scientist at the Maine Center for Coastal Fisheries, worked with Emily Farr, a recent graduate of Yale University, and assistant professor Christine Beitl of the Department of Anthropology to study how fishermen's changing access to fish species over time (which Stoll documented in earlier research) has affected their knowledge of the marine environment. Marina Cucuzza, a student in the UMaine marine science and marine policy dual degree graduate program, assisted with some of the interviews.
