I mean, if we are transitioning this thread into a thread on fishing for suckers, primarily the white sucker, I will add this. Most all large, limestone influenced streams have large white suckers in them. Bigger rivers like the Juniata, Clarion, etc all have large white suckers in them. I have caught some bigguns and they fight pretty hard.
There is one very simple reason that they are not a "preferred gamefish." They are too tough to target and catch reliably. They are harder to catch than bass and trout. Their feeding patterns aren't easily deciphered by the angler and they don't just key on to a hatch or a certain baitfish, so to speak. They are just too darn challenging. Obviously they are down there sucking nymphs and other critters up but.....
I don't know if White Suckers have the pharyngeal teeth like the common carp, but hopefully they learn to crush and eat mudsnails. Carp are able to crush and eat hard shelled critters which would most likely make them be able to successfully consume the NZMS. If suckers can, too, that would be amazing. Maybe it could keep the snail count lower in Spring, raise the numbers of white suckers, and grow some monsters......
