  1. Theme II: Fisheries DynamicsThe CIMAS Program Contributors David Die Maria Criales David Jones Monica Lara Jim Bohnsack Peter Ortner Bill Richards Jerry Ault Manoj Shivlani Monica Valle

  2. Strategic Plan - FISHERIES • Goal 1: Protect, restore and manage the use of coastal and ocean resources through ecosystem management by: • Monitoring and observing • Understanding and describing • Assessing and predicting • Engaging and informing • Managing resources CIMAS objectives for theme II

  3. Strategic Plan - CIMAS Objectives • Understanding and describing • Assessing and predicting • Engaging and informing • Describe functional bio-physical processes that control fishery impacts • Develop simulation models for protected species, ecosystems, and fisheries. • Develop procedures for the evaluation of regulatory options in management of marine fisheries and protected species

  4. From Florida Bay to the Gulf of Guinea Recruitment to south Florida estuaries Sailfish catches (source ICCAT) Assessment of highly-migratory pelagic fish

  5. 1. Understanding and describing (Local scale) Abundance of demersal zooplankton and small fishes OPC • Continuous counting of particles for sizes between 100um to 10 cm: • Migrations • Diurnal patterns • Tidal cycles OPC ADCP ADCP

  6. 1. Understanding and describing (Regional scale) Certain elements can be incorporated into the matrix of fish otoliths. These elements form the elemental fingerprint unique to the water mass in which the fish resided and can be used for elucidating recruitment pathways for juvenile fish. Recruitment processes in South Florida

  7. 1. Understanding and describing (Regional scale) Shrimp Post-larval transport into Florida Bay Peaks in the abundance of post-larvae coinciding with cyclonic eddies were detected passing through the Middle Florida Keys. Simulations highlight the importance of swimming behavior.

  8. 1. Understanding and describing (Regional scale) Large Eddy, Small Eddy--Supplying Recruits to the South Florida Ecosystem The eddy process provides a potential mechanism for retention, nourishment at the spawning ground and delivery to the nursery areas Contours of total fish larvae superimposed over Sea Surface Height Model

  9. 1. Understanding and describing (Basin scale) Yellowfin tuna: effect of uncertainty in fishery removals Bratio = Bcurrent/Bmsy Reporting of catch was assumed to have increased linearly in time.

  11. 2: Assessing and predicting (regional scale) Stocks of queen conch stock in the U.S. Caribbean are overfished and are undergoing overfishing. Stock Assessment Scenarios for Caribbean Queen Conch

  12. 2: Assessing and predicting (Basin scale) ICCAT assessments: billfish, tropical tunas White marlin

  13. 3. Engaging and informing (Regional scale) Effects of No-Take Zones on Reef Fish populations in the Florida Keys National Marine Sanctuary

  14. 3. Engaging and informing (Basin scale) Catch Framework for Management Strategy Evaluation Fleets Samples Stock Commission Develop software for simulations of fishery systems to evaluate management strategies Stock Catch TAC Compliance

  15. 3. Engaging and informing Center for Independent Experts Develop a system to provide independent peer reviews of the science carried out by the NOAA Fisheries to strengthen Quality Assurance efforts under the NOAA Strategic Plan. The CIE is evolving to cover all areas of science conducted by NOAA Fisheries

  16. Theme II: new horizons • Develop quantitative socio-economic indicators for fisheries sustainability (link to Theme IV) • Link estuary models to those from the reef ecosystem (link to Theme III) • Integrate basin scale oceanographic model to assessments of highly migratory species
