7 31 2014 oyster bay repro check

Kamilche shores, wa

Hi 60s to low 80s sunny

Participants: Sean Bennett and Jake heare

Performed anesthesia sop with insulation on treatment tub and ice blocks on recovery tubs.  Found very few brooders again. I think it is a stack effect due to the unholy amounts of mussels set on the trays and oysters. Tried to clean them off but too many. Mussels probably consuming all sperm in water column.
