4. Determine the influence of the ocean environment on the distribution and catch rate of king mackerel (Scomberomorus cavalla) http://la.climatologie.free.fr/lexique.htm Objective • Show the utility of routinely using satellite derived oceanographic data to understand coastal circulation and for fisheries management

5. Recreational King Mackerel Tournaments

6. Fisheries – SurveyWhere are the fish? • What pass did you leave from? • What time? • Where did you start fishing? • What time did you start? • What method of fishing was used? Troll? Anchor? Drift? • Number of fishing lines? • Number of fish hooked? • Number of fish caught? • Were bait fish present? • Did you see kingfish? • What time did you stop? • Did you fish anywhere else? • Did you run to next site?

7. King Mackerel Catch Data • Spring and fall 2004 to 2005 • 19 tournaments • 415 interviews conducted • 1,599 kingfish reported • 579 fishing locations • Spring and fall 2004 to 2005 • 22 tournaments • 666 interviews conducted • 2,008 kingfish reported • 792 fishing locations • Compared to: • oceanographic data from satellites • meteorological data from buoys

8. Remote Sensing • Sea Surface Temperature • AVHRR + MODIS • Chlorophyll concentrations • MODIS + SeaWiFS • Proxy for available biomass • Water-leaving radiance at 443 nm • MODIS + SeaWiFS • Water clarity index • Fluorescence Line Height • MODIS • Red tide

9. DegC 25 17 Frontal Detection Sea Surface Temperature (SST) 9 April 2005 • Adapted 2 automated frontal detection algorithms • Cayula and Cornillon (1992) • SST • Water clarity • Fluorescence line height • Canny Method (1986) • Chlorophyll concentration

10. mW cm-2 µm-1 sr-1 Tampa Bay 0.15 0.01 Fall 2005 and Red Tide • Decreased catch • Spring 2004: 444 • Fall 2004: 818 • Spring 2005: 538 • Fall 2005: 208 • Decreased observance of baitfish • Spring 2004: 54% • Fall 2004: 54% • Spring 2005: 51% • Fall 2005: 38% • Decreased water clarity FLH fronts November 12, 2005

11. Conclusions • High variability within fisheries data • Data from satellites and anglers successfully used to link environmental conditions to daily fisheries distribution • Continue to strengthen link between scientists and fisheries community

12. Implications Working together towards sustainable fisheries • Increased trust of the fishing community will yield more accurate and reliable data leading to better management policies • Better managed fish stocks will lead to a sustainable ecosystem ensuring the health of the fisheries
