The replies have described the program well. No Florida bass wouldn’t likely make it up there, as there is a famous study where bass from central IL were tested in MN waters and most couldn’t make it through the winter. Still, the program would work up there. It’s no different than cattle or dog breeders selectively breeding for the desired traits. For fish, in TX we take 13+ lb females and spawn them with 5+ lb males, most of which are descendants of previous 13 lb females from the program. It doesn’t take a biologist to figure out that if Shaq has kids with a 6′ woman, the odds are most of the kids will be pretty tall. Of course with humans, most kids make it to adult ages. For fish, if a 15 lb’er spawns in the lake, only a very few of her eggs make it to adult sized bass. In the hatchery, if she spawn successfully, most of the fry survive, so 1000s of potential Shaq bass get stocked into the lake. AFter the fish spawns in the program, most are released back to the lakes they came from, while a few are kept permanently for breeding purposes by the state and a few others are stocked into other areas (the angler’s private pond or Bass Pro aquariums). The fate of the fish is the dontating angler’s decision, thankfully, most go back to the lakes so we can catch them next year when they weight that much more. As for the fry, 50% go back to the lake where the fish came from and the other half are stocked where the state chooses. So, the lake where she came from benefits and other lakes that have good lunker bass potential also benefit.
TX is working to track the offspring in the future to see what type of impact this program has. One would assume it has a positive impact but nothing has been proven so far. After having lived in IL & WI in my earlier years, it is very nice to now live in TX where the Parks and Wildlife Department actively works to improve bass fishing through the ShareLunker program, slot limits on trophy lakes like Fork (16-24″ protected slot) and many unique limits on different lakes to try to optimize bass fishing for size and/or numbers. Not all of it works, but it’s good to see them try and they truly do listen to angler feedback.
