Ecosystem approaches to fisheries management recognize people as part of a socio-ecological system and consider links among environmental, economic, and societal goals for sustainability. Fisheries systems are challenged by change due to the climate crisis, increasing human use of the oceans, and regulatory complexity, which coupled with geographic variation in human populations and economies means impacts of policy choices will continue to not be felt the same across coastal communities. Decision support tools that recognize and provide insight into this variation are needed.
In 2022, the Mid-Atlantic Fishery Management Council completed a management strategy evaluation (MSE) to compare options designed to reduce discarding in the recreational summer flounder fishery, with a goal of increasing both harvest and recreational opportunities. Reducing regulatory discards within the recreational sector of the summer flounder fishery has been challenging: 90% of the recreational catch is released and 1 out of every 10 fish released ends up dying. Through a collaborative, stakeholder-driven, and science-based process, a modeling framework was developed that integrates a full summer flounder population dynamics model with an angler economic behavior model to understand how recreational behavior at the state level responds to changing regulations and flounder availability. Eight management procedures were tested under three different states of the world. The benefits of each management procedure were assessed using a suite of biological, social, and economic performance metrics across four management objectives.
Results showed there are management procedures that outperform status quo management at reducing discards and converting those discards into harvest while limiting risk to the summer flounder population. However, the relative performance of a management procedure was highly variable at the state or regional level, with negative recreational satisfaction outcomes for some states compared to status quo even when overall performance improved. These models and results can be used to directly inform recreational management, and provide both strategic and tactical advice for a variety of potential management priorities. The ability to compute likely outcomes of management options at the state or regional level provides a pathway for explicitly considering distribution of benefits when making management choices.
Dr. Gavin Fay (he/him) is an Associate Professor in the Department of Fisheries Oceanography at University of Massachusetts Dartmouth’s School for Marine Science and Technology (SMAST). Gavin’s work focuses using statistical and mathematical models for better ecosystem-based decision making for our oceans and the people who depend on them. He is interested in both developing new methods for statistical modeling, fisheries assessment, and ecosystem-based management; and also how open data science tools enable better co-creation, communication, and use of scientific results for application to management and policy. Gavin received his BSc (Hons) in Marine Biology from the University of Stirling (Scotland), and his MS & PhD in Aquatic and Fishery Sciences from the University of Washington, Seattle. At SMAST, Gavin teaches courses in statistics, ecological population modeling, science communication, and Ecosystem-Based Fisheries Management. Gavin has worked on assessment and management of fisheries and marine mammal populations in Alaska, the US west coast, the Northeast and US Mid-Atlantic, and in Australia. He’s also advised on fisheries management in Europe. He currently serves on the Mid-Atlantic Fishery Management Council's Scientific and Statistical Committee, as well as the New England Fishery Management Council's Ecosystem-Based Fisheries Management Plan Development Team.
