Kinda makes you wonder why they were never able to kill all the chubs when they poisoned it the last time.Chubs are tougher to completely eradicate than perch. Perch tend to stay in the main lake and are more likely to be exposed to the rotenone. Chubs routinely wander up every little trickle and into any protected side channel or backwater. So there are almost always at least a few juvenile chubs left unscathed by the treatment. And as soon as they grow bigger they reproduce...starting the cycle all over again.
Some people blame anglers for bringing in live chubs for bait. While that may be true in some cases, it is more likely that there were some that escaped the treatment.
