Estimating the Impacts of Cumulative Stressors on Fisheries Production in the Chesapeake Bay System with Atlantis
The Chesapeake system has many stressors that simultaneously affect its habitats. Atlantis models the variable effects of habitat change on managed populations by dynamically simulating the entire system, including habitats themselves (as food, refuge, and sources of chemical cycling) within the context of expected system change.
Current stock assessment focuses on estimating population abundance compared to accepted thresholds, but such efforts seldom consider the effects changing habitat have on productivity. This work begins to fill that gap, providing predictions of productivity under differing assumptions of habitat change.
