2. Where do we go next? Lyle Britt, Stan Kotwicki, Rick Towler, and Jim Ianelli Alaska Fisheries Science Center, Seattle WA.

4. It’s a lot more information! 40 44 51 58 78 112 160 180

5. Biologically Available Light Walleye Pollock in Nearshore Plankton Bloom 46% Reduction in Biologically Available Light!

6. 3 COMPONENTS OF VISUAL ECOLOGY 1. THE VISUAL ENVIRONMENT=BACKGROUND LIGHT CONDITIONS 2. THE SENSOR’S RESPONSE TO THE QUALITY (WAVELENGTH ) & QUANTITY (# OF PHOTONS) OF LIGHT 3. TARGET CHARACTERISTICS WITH RESPECT TO QUALITY ( ) & QUANTITY (# OF PHOTONS) OF LIGHT -Biologically Relevant Targets -Trawl Survey Relevant Targets

7. VISUAL COLORSPACE MAPPING LINGCOD LARVAE 3.8x Greater Contrast Between Target and Background CLEAR OCEANICNEARSHORE PLANTON BLOOM

8. Four aspects of light in water influence fish coloration: 1. Differential absorption of wavelengths with depth and distance; 2. Uniform attenuation with depth; 3. Symmetrical distribution of light around the vertical (brightest is overhead); 4. Visibility of objects a function of contrast (not resolution, as in air).

10. Visually Mediated Behavior
