Hey Casper, I thought I answered that in an e-mail a while back?

Same camera as Ed's. Pentax Optio W60.

I have bought two on ebay for $50 - 75.

As for the color, it comes out pretty good raw then as Todd showed here:

you can bump the settings afterwards in GIMP, Photoshop, etc.

Happy hunting!

An alternative explaination is that they use the tubercles for roughness to help keep in contact with the female during the act of spawning. It's hard to hold a gal when you don't have hands. If you watch closely during "clasps", the males will jut their heads into the side just behind and into the gill flap, which would explain the more developed tubercles on the head. In fact, it may be an interesting hypothesis to test on the extent of tubercles and how intensive the contact must be during spawning. Species like chubs only have them on their head because that's all they need to keep contact. Stonerollers and other nest associates are more on the fly and that's why they have the sandpaper down the body. Suckers get them everywhere (including the anal fin) to keep a rival from knocking them off, and may literally wrap themselves as best they can around the female.

I've seen Cyprinellas headbutting and biting each other quite a few times [and a few other cyprinids from other parts of the world with such armaments too]. The latest clip at CFI IIRC have Al shiner striking each other loud enough for the camera to record the sound.

I have too. But if it's solely for armor, then why have them on your anal fin?

I dont think anybody is saying or implying "solely" any single use. Tubercles are undoubtedly useful for multiple functions depending on species and where they are on the body: head-butting, side-slapping, visual intimidation, gravel moving, mate clasping, mate stimulation, etc. In Lythrurus matutinus (and perhaps other Lyth's I have not seen) the turbercles are very fine and "glow" bluish-white viewed from above over dark rocks, much like Cyprinella fins. That's got me puzzled, as they are not nearly so conspicuous (to a human) in side view.

I think they have multiple uses too. For example Abramis [European bream] uses tubercles both in fighting other males, show off, and rubbing females.

Just got out for the first time snorkeling this year. Lots of rain and cool temps this spring.

I went snorkeling in Big Creek in the Smokies near the picnic area today for father's day.

In the stretch I was in all I saw was lots and lots of juvenile rainbow trout and a few stonerollers (?).

I was really surprised. I had expected to see more species.

Water was really cold and moving very fast.

Has anyone else snorkeled that stream? Did I just miss the good areas or is there a reason there is such low diversity in that area?

Big creek is known to be a fairly nutrient poor stream even by Smoky mountain standards. I suspect that has something to do with the lack of diversity that you noted.

Big Creek is mostly rainbow trout

You might find an occaisional brook trout there as well

Just filmed this on Tuesday. What is the darter? I assumed it's a Tuckaseegee?

First rule of fish identification (unless you are going to have a preserved specimen I guess... but my first rule) = know where your feet are (or in this case your snorkel).

Petersons does not even give a picture for the Tuckaseegee Darter but does mention three subspecies of Greensides and then says that the Tuckaseegee may hybridize in some locations with one of these. So without a drainage, I dont think we could be absolutely positive.

But, just from the video I would say greenside or tuckaseegee for sure, yes.

And oh, I love videos that put the fish in perspective like that by coming up out of the water at the end and showing the waterfall and such.
