Adult C. virginica can live in salinities up to 35 ppt (Buroker 1983)".
But one of the problems with higher salinity waters is predation. When salinity is higher oyster drills become more numerous and predation rates are higher.

I will add to this about high salinity levels.
Perkinsus marinus a parasite that causes Dermocystidium Marinum (also known as Derma)= this parasite kills oysters.
The critical environmental factors which favor the proliferation of the parasite are
high
water temperatures and high salinities. Thus infections are more intense in the late summer, on
the seaward side of estuaries and during droughts.
Also when you control the salinity going in the lake the sediment will also be controlled it goes hand and hand really.
Most of this info that I post is in the oyster assessments that are on the LDWF website. Very informative for a person that is interested in these issues.
