As far as my comments about the forage fish goes, it would only make sense to thin out as much of the LMB as possible, then add them. Otherwise any new forage fish would be hard to establish. After thinning the LMB out, I would look into other forage with the help from the pros here. Once a specific type is determined, then find out what habitat they need to thrive. You may have alot of habitat in the pond now, but if it is not the right type it all goes to waste.
