If that's the case have you ever considered allowing them to do their thing sequestered from the smaller fish via a blocking net or even a cage with a tub of gravel in it? I know bass have been spawned in a raceway so...
Then once the fry hatch and move out of the net or cage that keeps the brood fish in, it's an easy matter of removing the broodfish.
I plan on doing this with bluegill this year and as you know have been doing it with yellow perch for a couple of years now.
Very good idea Cecil!
