All species were photographed underwater, not caught.  I realize that the picture quality might not be good enough for identification, but I thought that maybe I'd try.

 

Darters:

 

Tessellated or Greenside?  My hunch is Tessellated.  The known darters in this drainage are Rainbow, Fantail, Tessellated, and Greenside.

 

 

 

Cyprinidae:

 

 

 

 

Other...Northern Hog Sucker?

 

Here is a list of the cyprinids that could be in that stream:

Stoneroller Capostroma anomalum Red Shiner Cyprinella lutrensis Spotfin Shiner Cyprinella spiloptera Goldfish Cyprinus auratus Common Carp Cyprinus carpio Silverjaw minnow Ericymba buccata Cutlips minnow Exoglossum maxillingua Pearl Dace Margariscus margarita Bluehead Chub Nocomis leptocephalus River Chub Nocomis micropogon Bull Chub Nocomis raneyi Golden Shiner Notemigonus crysoleucas Comely Shiner Notropis amoenus Satinfin Shiner Cyprinella analostanus Emerald Shiner Notropis atherinoides Bridle Shiner Notropis bifrenatus Ironcolor Shiner Notropis chalybaeus Common Shiner Notropis cornutus Spottail Shiner Notropis hudsonius Swallowtail Shiner Notropis procne Rosyface Shiner Notropis rubellus Mimic Shiner Notropis volucellus Bluntnose Minnow Pimephales notatus Fathead Minnow Pimephales promelas Blacknose Dace Rhinichthys atratulus Longnose Dace Rhinichthys cataractae Creek Chub Semotilus atromaculatus Fallfish Semotilus corporalis

 

 

Thanks for your help in advance!

Greenside. Got me. Bluntnose. Hogsucker

[Chasmodes]

Thanks Matt. I think you are right, greensides! When I zoom in on the pick I can see green coloration in the "U"s and body, and colors on the dorsal! I didn't see that before!

The sucker might be a white.  Head doesn't look square enough for hogsucker.  Minnow shots are not clear enough to ID.

[Matt DeLaVega]

I looked at some juvenile white suckers this past weekend, and at the 1.25 inch size they were very similar to equal sized hogsuckers. Slightly less boxy head,  less pattern, and it is more broken with less uniformity and saddling. I would not doubt that that is a white either. I have a really hard time with photos. In hand I know right off except for little silvery ones, but looking at photos is really hard. I could sway either way. Photo angles really skew things for me. But for the meantime I am staying with hogsucker.

Greenside Darter, looks like Emerald Shiners, Bluntnose Minnow, need a better shot of the Sucker.

Thanks guys, much appreciated.

[Matt DeLaVega]

The shiners almost look translucent. maybe that is the photo? If not which of those possibilities fit the bill? i really have no clue, and agree that a better photo would help people help you. Anyway were they a very translucent fish?

I would feel comfortable eliminating these from your possible fish.

[Kanus]

I agree with Matt's elimination with the exception of one. In the first photo, with the two fish, I believe you have two different species there. The one not picking at the bottom has a pretty deep body and could possibly be a young Common Shiner. I'd vote either that or a comely, but I'm not familiar with emeralds. The one picking at the bottom has a more subterminal mouth and I think is a spottail shiner.

[smbass]

I think the minnows that no one was sure on are N. volucellus.

Thank you everyone!
