Thanks Brad.
Our prawns are also kept in 35-38 degree farenheit water too. So the SG doesn't need to be optimal because of the amount of oxygen they are actually consuming at those temperatures. I know the Fraser River plays a HUGE role in how high the SG is between Vancouver Island and the mainland. The difference between high and low tide within 20-30 miles of the fraser is around 1.012 on flood, and 1.019 on ebb. Pretty remarkable really. All quite interesting, thanks for the explanation!
