I catch these out of a local creek. I have no idea what kind of fish they are but they do get up to 12-14 inches. Any one ever use them as bait

Look like some kind of minnow,I'm not sure,but looks like it could be in that family.

I'm with Paul, it does look like a minnow... Almost like a rainbow trout-pike minnow hybrid :D

I don't know Erreck! This is a picture of a hitch that my kids catch in a creek that runs through our backyard. *Looks pretty close! http://momentoffame.com/photopost/data/526/medium/IMG_0983.JPG

Yes, it's a minnow (Cyprinid) for sure. I looked at it a little closer and change my answer from hardhead to Sacramento blackfish (Orthodon microlepidotus). A hardhead has a fewer scales along the lateral line, and a hitch has a lot fewer. Although we can't necessarily count them along the lat. line in these photos, we can tell that our new unknown fish has a lot more along the lateral line, i.e. the scales are much smaller...even if the pics are resized a little, the size of the scales in relation to the distance from head to back of dorsal fin still shows us that our new fish has really small scales.

Top photo: hitch (larger scales in relation to fish size)
Bottom photo: new uknown fish/blackfish (tiny scales...)

Scales along lateral line:
* * hitch: 54-62
* * hardhead: 69-81
* * Sacramento blackfish: 90-114

Fin ray count (dorsal, anal, pectoral, and/or pelvic) is another way to ID minnows, but for blackfish, those fine scales are all that is needed.

ps- these are native.

The color and the mouth don't look right for a Sacramento Blackfish. It's been twenty years since I've had any fish taxonomy courses and my mind is a little fuzzy. A lot of the cyprinids look alike on first glance. It would be a lot easier with a specimen in hand and a dichotomous key......

Cabbagehead,
You're definetely right, it's not a hitch. *Sure helps when you can see those pictures right next to each other. *Now I don't know what I'm more impressed with, your knowledge of fish, or your computer skills! *But I do know that you're better at both than I am! :)

Delta Rose, I agree, it doesn't really "look" like a Sac blackfish. Darn minnows. But those scales...hmm.. I give 80% confidence in my ID on this one.

And thanks Klamdog *;). For what it's worth, I have a degree in fisheries and spent a few years sampling juvenile fish in the delta. I got pretty good at ID'ing our delta fishes, down to 20 mm. We didn't get many SACBLA in our area though.

I also have to resort to a book now and then...Peter Moyle's Inland Fishes of California...good stuff.

i agree with Cabbagehead, it looks like a blackfish. If it was in his hand, I would change my answer to rosy chub

I have a degree in fisheries.

CabbageHead- Cool [smiley=cool.gif]- where'd you go to school? *BTW- I defer to your field experience- the only Sacto Blackfish I have ever had in my hands where in the 25-35 cm range- with your field sampling experience, you would know a juvenille better than most[smiley=thumbsup.gif]

The University of Montana in Missoula, but most of my minnow ID know-how comes from local fish-heads (UC Davis) like cadfly_1971. I even sent him this post for confirmation... he is much better than me.

fish-heads (UC Davis) like cadfly_1971.

Yup- I'm a fishhead myself- UCD WFB '86.....

If you ever meet cabbagehead, you will see why he is so smart. There is plenty of room for knowledge up there. ;D ;D

Definitely NOT a hardhead... Those look a lot like squawfish- I've seen plenty of them in the stretch of the Moke above Pardee.

Sac Blackfish is probably correct. Both splittail and hitch do have bgger scales. I know there are blackfish in a number of places...

Also, in the Delta, there is always a chance, I suppose, that any one of a number of cyprinid fishes could be blown out of a frieghter's bilges on any given day and some might take root... :-/
