The Guadalupe Bass is a species native to only Texas, USA. It ranges from the Edwards Plateau and San Antonio River headwaters to the Colorado River, Guadalupe River, and portions of the Brazos River.Guadalupe Bass prefer clear, fast-flowing waters with gravel beds that are used for spawning. The average Guadalupe Bass weighs about 1lb and measures approximately 12 in length, though individuals weighing up to 3.5lbs have been recorded. Like most bass species, the Guadalupe Bass feeds primarily on fish, crayfish, and insect larvae. Gaudalupe Bass are green to olive in coloration, with diamond to oval shaped markings along the lateral line that may extend towards the belly. The jaw does not extend beyond the eye, and there is a series of teeth found on the tongue that makes them easily distinguishable from the Small and Largemouth Bass. Guadalupe Bass can be caught on lures such as plastic worms, flies, grubs, tubes, and creature baits, as well as crankbaits, spinners, and topwater baits. The Guadalupe Bass neared extinction in the late 1900s due to habitat loss and genetic hybridization. Although they are still threatened, restoration initiatives are currently in place through the Texas Parks and Wildlife Department.
