7 2 2014 Manchester Repro Update

Manchester WA

Mid 60's to High 70s Sunny

Participants: L. Christine Savolainen and Jake Heare

Used the Anesthesia SOP with the insulation and ice blocks on the treatment tubs. Found absolutely no brooders. This site just does not have the conditions necessary for these animals to spawn. It must be due to the colder deep water that comes into the bay off the Sound.
