3 Our Mission: Mr. Clams Seafood Company has hired us to find the best site to place an aquaculture farm in the San Juan Islands area.

Overview of two species for aquaculture Native to Japan 1-3 years to develop to market size 1.

4 Overview of two species for aquaculture Native to Japan 1-3 years to develop to market size inches long $10/pound value 98% of world s oyster production! Generally do not produce pearls. Geoduck Native to our region Name means dig deep (Nisqually tribe) Siphon can be 3-6 ft, up to 15 pounds! Among oldest living animals (168 years old!) $10/pound in US, $40/pound in China

5 Sample Sites Obstruction Pass Pelican Beach Spencer s Spit Huckleberry Island East of Lopez

6 Cool science materials we used: Plankton Nets Niskin Bottle Sediment Sifter Bucket-ometer Graduated Cylinders Colorimeter

7 Methods/Procedure Sailing team navigates to deployment site Deploy plankton nets at surface and at 20 meters for a 5 minute tow. Collect water sample with bucket at surface and using niskin bottle at 20 meter depth. Settle plankton to measure biomass. Use colorimeter to measure salinity, dissolved oxygen, ph, and temperature. Collect and sift a sample of the sediments. Record all data on Motherboard
