7 16 2014 Manchester Repro Check

Manchester WA

Low 70s to Mid 80s

Participants: Alicia Godersky and Jake Heare

Performed the anesthesia SOP with insulation and ice blocks on the treatment group and tarp over the recovery and pretreatment tubs. Finally found multiple brooders in one population. If you can guess the pop, you can consider yourself an Oly Whisperer. The brooding animals were also much smaller than expected. Half were less than 20 mm which is quite odd.  Also temps fluxed on the tubs on the dock even with replacing water, the combination of sun and no breeze just baked the docks.
