Monthly changes in mean ova diameter and gonadal weights indicated that spawning of rough shiner, Notropis baileyi, a cyprinid recently introduced in Halawakee Creek (Apalachicola River Drainage), Alabama, occurred during early or middle May through late September or early October. Peak spawning occurred in early or middle June. Several complements of ova matured. Fecundity was linearly related to length and weight of the fish. No significant correlation existed between the diameter of ova and fork length of fish. Versatile food habits, a long successful spawning season and favorable habitat are believed to be the key to the success of this shiner in Halawakee Creek.
