Snipe,
Thanks for dropping by and adding all of that additional information!
Having a bunch of small and fast OSS as forage for the LMB does sound like a recipe for a stunted sunfish population that cannot be controlled by the top predators.
Even if the saugeye were picking them off at night, then the saugeye probably outgrew their forage so quickly that they could not keep the small spawning-size OSS in check.
