Samples of the Skygazer Shiner, Notropis uranoscopus, were taken from the Tallapoosa River from 1988 to 1989. Examination of ovarian condition in female fish showed reproduction occurred from April to August. Clutch size of females varying in length from 40.4– 46.2 mm standard length, and collected in April 1988, ranged from 336 to 582 eggs and was significantly related to female size. Mean female ovum diameter ranged from 0.84 to 0.92 mm and averaged 0.87 mm; there was no significant relationship with female body size. The Skygazer Shiner appears to exhibit an “opportunistic” life-history strategy.
