Abstract

Habitat suitability maps are provided as tif files embedded in a Word document for each of the four forage fishes studied: juvenile spotted hake, juvenile spot, juvenile weakfish, and bay anchovy. Suitability maps are provided for each season and year, 2000 – 2016 for tidal waters of the Chesapeake Bay. Habitat suitability indices range between 0 (red) indicating poor habitat to 1 (blue) indicating most suitable habitat. These indices were estimated using procedures described in Fabrizio et al. (2021; see associated publication below). Estimates of the annual extent of suitable habitats baywide, and for Maryland waters only and Virginia waters only are provided as CSV files, one file per species.

• Juvenile Spotted Hake Habitat Maps: Heat maps of habitat suitability indices for juvenile spotted hake in Chesapeake Bay. Contains 67 maps, one for each season (winter, spring, summer, and fall) in each year (2000-2016). All maps are in tif format.
• Juvenile Spot Habitat Maps: Heat maps of habitat suitability indices for juvenile spot in Chesapeake Bay. Contains 67 maps, one for each season (winter, spring, summer, and fall) in each year (2000-2016). All maps are in tif format.
• Juvenile Weakfish Habitat Maps: Heat maps of habitat suitability indices for juvenile weakfish in Chesapeake Bay. Contains 67 maps, one for each season (winter, spring, summer, and fall) in each year (2000-2016). All maps are in tif format.
• Bay Anchovy Habitat Maps: Heat maps of habitat suitability indices for bay anchovy in Chesapeake Bay. contains 50 maps, one for winter, spring, and summer in each year (2000-2016). No habitat maps were constructed for fall. All maps are in tif format.

Funding

Funding for the creation of the habitat suitability maps was provided by the NOAA Chesapeake Bay Office. Funding for the fish catch data was provided by the Virginia Marine Resources Commission, the US Fish & Wildlife Service, and VIMS through annual awards to the PIs (Fabrizio and Tuckey). In some years, funding was provided by the NOAA Chesapeake Bay Office.
