Howard, are you feeding? I put in a few Tilapia as added forage as well.. they spawned a few times but seems like the smb and bg must have cleaned all thy fry up as all I see are YOY BG - not tilapia.
My tilapia haven't helped at all with FA this year, but oddly enough the shiners I put in this week have already started making a dent in the FA in one a little cove I have. I was thinking of the female LMB next year too, and maybe a couple HSB - probably one or 2 of each.
Did you put in blue or mozambique tilapia??
