Caught nice bait shrimp in the Wando Sat. lot’s with black gill. I am no biologist, however I believe it weakens their immune system enough that they never make it out of the creeks and rivers for the baiting season. Those DNR fellows will have to start putting a satellite tag on them to see how far they travel with the disease. I have seen plenty of shrimp in Bull’s Bay during the baiting season with black gill.
