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: 密西西比河流域從俄亥俄州與西維吉尼亞西至明尼蘇達州與內布拉斯加而且南至岸灣; 在德克薩斯與美國新墨西哥州的岸灣流域從阿拉巴馬州的 Choctawhatchee 河與佛羅里達至 Rio Grande, 與墨西哥。
