I spent last week kicking around parts of Tennessee and Alabama, and lots of fun fish were caught, like the Clinostomus below. Attempts to get popeye shiners (thanks, NANFA Conservation Research Fund!) out of the Duck River resulted in only a single specimen - clearly not good enough to examine reproductive behavior. Hopefully we can wrangle some more up before their spawning season is over...

More pics in the NANFA gallery, and even more to come as I find the free time to edit them.

Cheers,
Dave

What has bug me for a long time is that what is the breeding color of East Coast rosyside. Is the color the same as TN rosyside?

Nope. Not even close. The "smoky dace" from the highlands of NC, SC, and GA is even crazier looking, much more purplish.

Steve Walsh, of USGS in Gainesville, supposedly has an elevation of the Tennessee/Cumberland River form (now recognized as C. funduloides estor) and a description of the smoky dace in manuscript form, but I don't know when it will get published...

cheers,
Dave

The picture shows what I've always noticed about rosyside males, that they have a light tuberculation. At least the ones in the central Tennessee Valley do.... And Dave, I've been collecting telescope shiners on a monthly basis since February. None of our males show any obvious tuberculation. Have you ever noticed any in popeyes? I've noticed it in silverstripes (stilbius) and I'm wondering if there's some variation within this subgenus for tuberculation.

Thanks. So the eastern RSD will become "Smoky Dace" sometimes in the future. What does the ester look like?

BTW now the blacknose dace are 2 species?
