An update from Katie’s

I am continuing work today with relaxing the oysters.

There are 3 oysters in 50g/L MgSO4
There are 5 oysters in 70g/L MgCl2
There is also a 1:1 ratio of salt/fresh water to control for salinity.
After 30 minutes, 1 oyster was semi-relaxed in MgSO4, It would stay open
after being touched and handled underwater, but when I took it out of the
water it would close instantly. I don’t know if that has to do with the
mass of the shell or if it was not completely relaxed yet. I left it in the
water for another hour and was in the same state at that time. I took it
out and put it into the fresh water.
At the hour and a half checkpoint, 1 other MgSO4 and 1 MgCl2 were also in
that “semi-relaxed” state.
At two hours, I removed all of the oysters and put them into clean
MgSO4 oysters are all labeled with red nail polish, MgCl2 are unlabeled.
