This could be a good thing on this lake, however how much does lgm bass predation effect walleye recruitment vs prespawn NA harvest? I would have to suspect that some of the decline is related to actual spawning success.
Also interested in weed growth and pervasiveness, influence on various populations. There are many more predators of the young walleye than just bass. At what age are the dents in population occurring? Do they actually live to reach fingerling size before getting eaten? Has that been established?

Just curious as to what is what, interesting problem.
