8 7 2014 Oyster Bay repro check

Shelton wa

Mid 60s to low 80s sunny

Performed the anesthesia sop with insulation on treatment tub and ice blocks on treatment and tarp cover on the Pretreatment and recovery tubs. It appears that the mussels have a significant effect on brooding as today's trays were less cover or not covered at all compared to last weeks. I saw a substantial number of brooders in the southern pop and a few in the northern and dabob pop.  We could almost assume that the other trays should be brooding in the same number as the "clean trays". We'll find out next week if the cleaning job I did last week helped out.
