Based on gonosomatic indices and ovum diameter frequency distributions, the redear sunfish spawns from May through July. Fast growing 2-year-old (above 150 mm) and older fish attain sexual maturity. Mature ovum diameter ranged from 0.60 to 1.30 mm. Fecundity • total length, • total weight, and • age relationships were: 1nF = 5.95242 + 0.01967L (r²= 0.90), LnF = 8.80328 + 0.00594W (r²= 0.92), and 1nF = 8.19332 + 0.50231 A (r² =0.83), respectively.
