7 18 2014 fidalgo bay repro check

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.
