Spawning occurs April to June in Louisiana (Suttkus 1963), possibly January to September in Oklahoma-Texas (Echelle and Riggs 1972). Seasonal variation in ovarian weight indicated peak spawning in July-August in northeastern Mexico (Garcia de Leon et al. 2001). In Alabama, females mature at age 11 and live to age 50; males mature at age 6 and live to age 26 (Irwin, cited by Boschung and Mayden 2004).
