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.

Also toured the new hatchery at Manchester with Ryan, saw a chipmunk, and the canadian goose on the docks hatched 4 of it 5 eggs. They goslings were adorable.
