The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).北美洲: 阿肯色河流域從阿肯色州西部到堪薩斯州西部,俄克拉荷馬州西部, 德克薩斯與東北方的美國新墨西哥州。
