Can you do a seine survey ? I am trying to get a feel for if there are multiple year classes of CNBG. If there are you are in good shape as your LMB at 2-3in will not be able to eat your reproductive forage base. If your first CNBG spawned last year then by the time you stock LMB you will have 3 year classes. All of those last year yoy would not have washed out as per Theo's post.
