There is no need to kill and remove any fish species unless in a study area.
Quirk Creek is removing brook trout to protect native cutts and bulls.
Removing suckers and mountain whitefish does nothing to benefit the health of a stream. For years...even the mentality in F&W was to remove "undesireable" fish such as mountain whitefish. However as time passes we in the fishing interest group realized that the whitefish fry and young of the year are an important food for larger bulls, cutts and rainbows.
The same applies to suckers. Nature actually staggers spawning so that the predators have a great food source to grow on.
In lakes...sucker fry feed the next crop of pike and walleye.
In rivers...whitefish and sucker fry also benefit the predators.
I never kill fish needlessly unless I am eating them.
