from What i gather from reading, the plan is to stock the native walleye in the river above the lake. To, What i guess is to establish a spawning population of the native strain walleye in that lake as you have mentioned in the face of the hybrids. It sounds like a noble effort to stock the native walleye in a place where they were not dominate in the first place and i do not believe that the brood stock will come from there as they are not there from what I understand, so it will be a kind of experiment, to see what happens, and the avoid stocking native walleye in their original waters for fear of cross contamination with the erie strain which continues to be stocked in the native walleye drainage. To have a good walleye population on Barren with the hybrids, I would guess that you would end up with the dumping in of the erie strain and stocking a lot to have a good fishable population while the hybrids are stocked. If you cannot stock their native habitat and get a decent population(without trying to date) then it pretty much does not matter which walleye you stock does it,Just my opinion again and it is worth little
