Research to Inform the Development of a Bioeconomic Model for Improved Management of Hypoxia Impacts on North Carolina Brown Shrimp
Scientists at Duke University, funded by the National Centers for Coastal Ocean Science’s Coastal Hypoxia Research Program, have found that hypoxia can reduce brown shrimp growth in North Carolina estuaries both directly (by exposure to low oxygen) and indirectly (by limiting food resources).
These findings will inform the development of a bioeconomic model to predict
- ecological effects of hypoxia on brown shrimp and
- fisherman behavior in an effort to trace how changes in shrimp abundance and size affect economic decisions about when and where to fish.
Brown shrimp are an important fishery in the southeastern United States and exposure to hypoxic waters has increased over the past several decades. This research will provide a valuable tool for managers and policymakers to evaluate the ecological and economic consequences of coastal hypoxia, as well as the efficacy of environmental policies.
