  1. Linking Coastal Watersheds to Fish & Fisheries Felicia Coleman Florida State University Coastal & Marine Laboratory Photo by Richard Bickel

  2. Gulf of Mexico Zonation 38 % Coastal 22 % Shelf (< 200m) 20 % Slope*(200 - 3000m) 20% Deep Sea (>3000 m) Linking Coastal Watersheds to Fisheries Productivity EGoM > WGoM *most complex on earth From: Gulfbase, www.gulfbase.org

  3. Circulation - The Loop Current Linking Coastal Watersheds to Fisheries From: The Sustainable Seas

  4. Nutrient Input - freshwater discharge Linking Coastal Watersheds to Fisheries Links terrestrial & marine ecosystems Groundwater , springs

  5. Nutrient Input - freshwater discharge • Chlorophyll plumes from • Mississippi River • Apalachicola River Linking Coastal Watersheds to Fisheries Felicia Coleman

  6. Nutrient Input Linking Coastal Watersheds to Fisheries The Dead Zone The Green River Phenomenon • same season, same time as • peak spawning for: • Gag • Red Grouper Mississippi - BAD Apalachicola - GOOD

  7. Habitat Linkages Linking Coastal Watersheds to Fisheries From: Heck et al. 2008

  8. Habitat Linkages – life cycle Linking Coastal Watersheds to Fisheries From: Heppell et al. 2006

  9. Habitat Linkages – fisheries Linking Coastal Watersheds to Fisheries Fishing Sites

  11. Linking Coastal Watersheds to Fisheries Felicia Coleman

  12. Linking Coastal Watersheds to Fisheries Chlorophyll based on March SeaWiFS ocean color satellite data (from Dr. Steve Morey et al., FSU COAPS) Felicia Coleman

  13. Summary • The benefits of river flow extend far beyond the boundaries of the bay • That river flow delivers nutrients offshore that support a highly productive fisheries • Those fisheries deliver billions of dollars to coastal communities and those industries that depend upon them Linking Coastal Watersheds to Fisheries
