Big Texas females are paired with pure Florida males
 

Texas Freshwater Fisheries Center (TFFC) is headquarters for the Budweiser
ShareLunker program, which encourages anglers who have caught 13-pound-plus
largemouth bass to lend or donate the fish to Texas Parks and Wildlife
Department (TPWD) for spawning purposes. In the production hatchery, the big
females are paired with pure Florida strain males. Superior genetics from
ShareLunker females and their offspring are used to improve the quality of
largemouth bass stocked in Texas waters. Ultimately, TPWD hopes to produce
the next world record largemouth bass.
