Oysters in BL

[T-TOP]

The living reefs built on south end of lake have died due to salinity conditions in lake. 50 acre living reef will be built this year north of the harvest line. Until salinity levels are controlled the oysters on south end of lake will suffer, unless it just keeps raining.

This is not exactly true. The reefs in the S end of the lake were destroyed by overharvesting, including a lot of illegal taking, in 2010.

High salinity levels have prevented the reefs from coming back and hindered restoration efforts, but it is well documented that overharvesting, rather than high salinity killed the reefs.

Since lower salinity levels are needed to restore reefs (or build new ones), restoration efforts do well to proceed further N in the lake where salinity levels are lower. Building of reefs for habitat improvement also does well to work in areas protected from harvest.

I am refering to man made oyster reef. Built, growing, never harvested and died due to lake conditions. I am sure you are in contact with Patrick B. ask him he can explain it. The lack of oysters in the south end of the lake is thought to be due to lake conditions, not harvesting. Where is it documented? Not to argue that the oyster dredging should be stopped, I think it should. But don't get sidetracked into thinking that stopping that will cure the problem.

No doubt that controlling salinity is key to oyster restoration, and that high salinity has hindered restoration efforts since 2011.

But the above references and attached figures make it clear that harvest pressure led to the oyster decline on the E side in the 2010-2011 harvest season.

average salinity levels 2008-2013, 14.05, 15.27, 15.62, 20.56, 16.64, 17.95. oysters prefer the salinity below 15.00 to reproduce and be healthy.
Drill snails are a serious threat to oyster reefs also.
