Description:This report presents results of an approach to examine the potential changes in selected fishery habitats as affected by alterations in freshwater inflow. Although the focus is one of freshwater inflow as it primarily affects salinity, the analysis is conducted in the context ofthe other necessary habitat parameters. Thus, the analysis is based upon habitat suitability as determined by the combination of salinity (ppt), water temperature (C), dissolved oxygen content (mg/1), substrate type, bathymetry (m), and the presence or absence of submerged aquatic vegetation and emergent wetland macrophytes, as they vary in both time and space. Eastern oyster (Crassostrea virginica), white shrimp (Penaeus setiferus), and spotted seatrout (Cynoscion nebulosus) were selected to study via habitat suitability index (HSI) modeling. Models were developed for Pensacola Bay, Florida; however, the model was designed to be applied across a wide range of estuaries in the central Gulf of Mexico.
