Pics have brooders between tube label and caliper. Closed oysters on the same tile. Open oysters on the other three tiles. Some oysters on closed/brooder tiles are open and vice versa due to the fact of the guys glued to the tiles.

Oyster bay wa
High 60s to low 70s partly cloudy
Performed the anesthesia sop with insulation on treatment tub and a tarp on the Pretreatment and recovery tubs. Brooding back to normal with most brooders in southern pop, and equal numbers between north and dabob. Also crab fresh cleaning salt water lines used their water for Pretreatment but not for recovery because pump was shut down.

Participants: Joseph Stevick and Jake Heare

Also took pictures of the entire population. In the pics, the tile with the caliper and label tube are the closed animals except for the animals that are between the tube and calipers which were brooders.

Anacortes, WA
Mid 60s to mid 70s
Participants: alicia Godersky and Jake heare
Performed anesthesia sop with insulation on treatment tub. Found brooders in only the dabob pop. It seems that they spawn later in the season but in smaller number. We will see in the coming weeks. Also treatment was surprisingly ineffective with no discernable reason. Water was calm. Temps were stable. No movement while in tubs. Full treatment strength and time. Hopefully it was a fluke.

Oyster bay
High 60s to high 70s
Participants: alicia Godersky and Jake heare
Performed anesthesia sop with insulation on treatment and tarp with ice blocks on recovery tubs. Very heavy mussel set on all trays and oysters. Possibly causing spawning issues. Only one population had brooders which is very different than in previous weeks. The one pop was the dabob pop with 5 brooders, one of which looked like aborted spawn.
