Lusk is a big proponent of Threadfins, maybe he can shed some light on what may have caused ML to have issues getting them to survive.

For me, I'm trying every forage fish I can get my hands on + feeding daily now. My Tilapia do fine, but die around 50 degrees, my threadfins should make it 10 degrees below that. Bgill are over abundant, Emerald and Golden Shiners hit worms ! My LMB, HSB, Crappie & CC predators currently can't keep up with my forage offspring...I like that. Here's a Golden Shiner that should be reproducing any day now.
