good response.trout,wipers,saugeyes,along with other species are stocked to enhance and improve fishing opportunities for many people.the fact that some people have preferences for certain species doesn't mean that all the others should just be forgotten.bass,walleye,crappies get supplemental stockings in places where they cannot reproduce in substantial numbers to maintain a quality fishery.the hybrids fill a void,as you said.
as for saugeyes being stocked just to make money from the people who fish for them,i can't quite figure that one out,as before they were bred,nobody fished for them,cause they didn't exist.so there goes that theory out the window

they were bred in order to fill that "void".and yes,now they are very popular and more challenging than a lot of other species to fish for.and i,d probably travel to lake erie to fish for them,moreso than i would walleye,if they were stocked there
i even go to a local lake a few times a year for those lowly trout.though i do hit it for a couple big smokers/grillers when they stock the big ones once a year,most of my trips are at times other than the stocking days.it's enjoyable and not quite so easy to string a few at those "other" times.
i think we all need to kinda get on the same page as far as fishing as a common interest instead of promoting our personal agendas and downgrading those of others.
as for the DNR,i think,overall they're doing a good job along these lines,but nobody's perfect.
