Seems pretty expensive. I just bought some for $10 a pound 3-5inches. I am in the same boat I drove to get bass from overtons last year but it is an 8 hour round trip.
Stockers should be a minimum size of 6-9" with the 6" getting eaten and distracting predators till the larger ones can seek cover and acclimate to the surroundings. I'd estimate 40-60% of the 6" fish becoming snacks, but overall weight is comparatively low in a 10 pound stocking of mixed, larger sizes.
One pound of 3-5" Tilapia should be from 40-100 fish, and I'd estimate all but about 50% of the 5 inchers will become snacks within minutes of being stocked. Any tilapia avoiding predation for 10-12 hours will likely be fine. 5" Mozambique tilapia will be sexually mature, but will have low reproduction numbers till reaching about 8" in size.
1-3" tilapia stocked with even 6" LMB present, will almost all be ravenously snacked on.
