Ryan, I agree with ML about increasing your predator base with LMB and/or HSB to attempt to control your gizzard shad.

I don’t agree however, on his thoughts about stocking fingerling HSB with adult predators.
Predation has been much higher than 50% in my case – perhaps closer to 80+ %.
In order to maximize predation, I would stock the largest HSB available.

IMO, ML was pushing the envelope with his experimental GSD program, based on personal emails at the time.

Personally, I do not think CC on steroids are fast enough to catch gizzard shad…

Good luck with your GS elimination problem – I would hit them hard and I would hit them fast with largest predators available – a bargain compared against draining and starting over.
