Apparently A New Species Record In The Flint River

I took the Ichthyology class out to the Flint River yesterday to sample fishes. We found two species that I've never seen there before. One, the Bigeye Chub, is not a big surprise to find there. The other, which is still only a tentative ID, is the Silver Shiner, Notropis photogenis. Silver Shiners are fairly common just north of here in Tennessee but there are few recent records of them in the northern tributaries to the Tennessee River, mostly from Shoal Creek. Yesterday we netted four of these fish in the Flint. It's possible that they're Emerald Shiners. I'm going to send two of them to Dave Neely for a second ID opinion. There is no record of the species in the Flint, so that would be an interesting range extension. The picture below is big, so it can be easily enlarge for a closer look.
