6 4 2014 Manchester Repro Check

Manchester WA

Mid 60s to Low 70s

Followed the Anesthesia SOP to check for brooding oysters. Found no brooders. Water temperatures we also quite low. Last week the surface water temp was around 13 C. This week it was closer to 8 C. I think the bay underwent another turn over event which may lead to either a much later spawn timing for the oysters or an abortive spawn which we will not catch.
