They are named after the Guadalupe River, which runs through central Texas. A study of the biology, movements, behavior, and physiology of largemouth bass (Micropterus salmoides) from a low-salinity marsh in Lafourche Parish, Louisiana was conducted from March 1985 to December 1987. During a flood pulse event on the Pedernales, the Guadalupes didnt leave the river channel and move to slack water in the shallows, as did the smaller forage species.
