2track, lethargy is only a minor factor in a fresh stocking of tilapia. The small tilapia, freshly stocked in a new enviornment and after a haul are EASY prey for anything that can open it's mouth wide enough. LMB can eat a tilapia close to half it's own body length in size.
In Bill's scenario with 3-4" tilapia and 13-15" predators, I'd expect 80% or more loss to predation at any temp inside of 30 minutes of stocking...just an educated estimate....
