The threats affecting living marine resources are diverse, including overfishing, climate change, and pollution. In response to long-term challenges in fisheries management, a more holistic evaluation of the natural and anthropogenic drivers of populations sizes is needed. Ecosystem management (EM), a suite of strategies that incorporate ecosystem considerations into fisheries and ecosystem management, can be difficult to implement in practice. In the Mid-Atlantic, efforts to implement EM are ongoing; one output has been the annual ‘State of the Ecosystem Report’ for the region, synthesizes available data on a variety of environmental, ecological, and socioeconomic factors. Historically, the data needed for …

Historically, fisheries management has been based on the results of single-species stock assessment models that focus on the interplay between exploitation level and sustainability. There currently exists a suite of standard and accepted analytical frameworks (e.g., virtual population analysis (VPA), biomass dynamic production modeling, delay difference models, etc.) for assessing the stocks, projecting future stock size, evaluating recovery schedules and rebuilding strategies for overfished stocks, setting allowable catches, and estimating fishing mortality or exploitation rates. A variety of methods also exist to integrate the biological system and the fisheries resource system, thereby enabling the evaluation of alternative management strategies on …
