Officials to test oyster bars on the western portion of the bay for contaminants

Seafood workers and staff with the Estuarine research reserve have agreed to test oyster bars on the western end of the bay to see why there isn’t much spat on those bars.

Spat are baby oysters.

County administrative director Alan Pierce said there appears to be a strong spat set on the eastern end of the Bay, but that is not the case on the western end.

There is some spat on the Miles and Hagan’s Flat oyster bars, but not nearly as much as there is around Cat Point and East Hole.

One of the reasons for that is because there aren’t as many mature oysters on the western end of the bay to produce spat, but there is also a concern that the fossilized shell the Department of Agriculture used in 2009 is somehow causing a problem.

The concern is that there may be some contaminant on the fossilized shells used in the western Bay that is leaching into the water and contributing to the poor spat set.

To see if the concern is justified, The Apalachicola National Estuarine Research Reserve along with oyster harvesters will take substrate samples from the Miles, Hagan’s Flat, Summerside, and then as a control site- Cat Point.

The substrate will be tested for the presence of oil, dispersant, and any other foreign factor that could somehow affect spat.

The testing will serve another purpose.

If there is going to be extensive re-shelling of the oyster bars to help rebuild the oyster population, then the county needs to know that the shell stock that they are using is safe for the Bay.

And the only stock they can get in enough quantity to do the job is the fossilized shell.


A date for the testing has not yet been set.
