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.

Numbers as follow.
