Checking on outplanted juveniles:

  • -0.76 low tide
    • We planted on very low point of the beach so it goes underwater very quickly. The ferries were very busy so I got out there alter than anticipated. I cut open a quarter of the tubes for thorough inspections. I checked another 50% without cutting open the tubes because the tide was coming in quickly, but it was difficult to see anything with the mesh shadows.
  • 3 zip-ties on each mesh tube were hard to cut off (return with more people!)
  • In the tubes:
    • 3-4 crabs (up to 3 inches big)
      • Many of the tubs had crabs the crabs were crawling in and out of
    • Cockles
      • Difficult to tell if holes are geoduck or cockles
        • Would recommend coming back with the intention of digging them up to be sure of geoduck survival
