4. Objective  Show the utility of routinely using satellite derived oceanographic data to understand coastal circulation and for fisheries management  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

5. Recreational King Mackerel Tournaments

6. 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? Fisheries – Survey Where are the fish?

7. Spring and fall 2004 to 2005  22 tournaments  666 interviews conducted  2,008 kingfish reported  792 fishing locations King Mackerel Catch Data Spring and fall 2004 to 2005  19 tournaments  415 interviews conducted  1,599 kingfish reported  579 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. Frontal Detection  Adapted 2 automated frontal detection algorithms –Cayula and Cornillon (1992) SST Water clarity Fluorescence line height –Canny Method (1986) Chlorophyll concentration Deg C 25 17 Sea Surface Temperature (SST) 9 April 2005

10. 0.15 0.01 mW cm -2 µm -1 sr -1 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 Tampa Bay

11. Conclusions  Data from satellites and anglers successfully used to link environmental conditions to daily fisheries distribution  High variability within fisheries data  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
