<p>Hello all, I remember a while ago reading about the spawning temperatures of redhorse, but can't seem to find it anymore. Can anyone point me in the right direction? I'm specifically wondering about black redhorse.</p>
For black redhorse info, I've got a copy of Fishes of Missouri in front of me that puts thei Ozark spawning run in late April-Early May. Of course, this might be later up north, and it might be later this year because of the way the winter failed to exit properly. Fishes of Tennessee says 15-18 degrees celcius, late April and Early May in Illinois. Deeper, faster water with larger gravel size than golden redhorse use. Goldens spawn at 16-21 degrees celcius - so just after the black redhorse. Hope this helps.
Last year I caught two black redhorse, one male one female, both in real juicy spawning condition. Mid to late may is probably best to look for spawners.

The redhorse chart Olaf made has the spawning temp listed as follows:
Black 56
Golden 60
Silver 56
Shorthead 47
Greater 64
River 72
Hope that helps
Awesome, this is exactly what I was looking for. Thanks a bunch guys!
