    You were spot on, Doug! Tiny, young-of-the-year Dungeness crabs up there that you’ve pictured! I notice you submitted this one as an opportunistic report (which we don’t include in our scientific dataset. If you actually did search for the set time following protocols, I’m happy to get that updated for you to “Timed Search”. Thanks so much!

  • Yes, Lisa. Please update to “timed search” Thanks
