Sexual maturity of striped bass, Roccus saxatilis (Walbaum), was investigated in the Albemarle Sound-Roanoke River system of North Carolina during the periods October 1956 through January 1957, October 1957 through April 1958, and April through September 1960. A method which permitted the determination of maturity through the measurement of ova was used. Percentages of mature female fish during several months prior to spawning are given by age group. At age-group VII and older, there was evidence of intermittent spawning and the possibility of cessation.
