The Florida largemouth bass, also known as the Florida bass, is a subspecies of the largemouth bass, which in turn is often called a northern largemouth.
This fish occurs naturally in Florida. Mixtures of it and northern largemouth are called intergrades, as they are neither pure Florida nor pure northern strains. These fish occur from northern Florida to Maryland. Florida bass grow to trophy size more readily than do northern largemouth bass. They have been stocked in many states, including California, which has produced near–world record 22-pounders from transplanted stocks, and in Texas, which has completely transformed its big-bass potential by stocking this fish.
