Peter -
I'll look up the articles for you.
My co-worker, Jack Killgore, spawned C. venusta in a flume by stacking clay
tiles together with slicone beads separating them a few mm and providing a
readily accessible crevice (so eggs could be counted). The tiles were placed
on top of plastic jars.
Read about them here:
Baker, J.A., K.J. Killgore, and S.A. Foster. 1994. Population variation in
spawning current speed selection in the blacktail shiner, C. venusta. Env.
Biol. Fishes 39: 357-364.

American minnows: direct evidence of the occurrence of multiple clutches in
the genus Notropis. J. Fish. Biol. 28: 343-357.
