Abstract
    Catch per unit effort (CPUE) data for Spanish mackerel, Scomberomorus maculatus, over a broad geographic area were obtained from charterboats. In 1982, a survey was initiated to obtain daily catch and effort data on fishes commonly caught by charterboats in the southeast United States. Boat effort and Spanish mackerel CPUE data obtained from this survey during 1982-85 were analyzed. The offshore fishing zone (> 10 fathoms) received the highest amount of trolling and "other fishing" efforts; the nearshore fishing zone ( less than or equal to 10 fathoms) received the second highest trolling effort and lowest "other fishing" effort; the estuarine fishing zone received the lowest trolling effort and the second lowest "other fishing" effort. CPUE of Spanish mackerel by "other fishing" was much lower than trolling for most areas and years. CPUE was highest in the estuarine zone when compared with the nearshore and offshore zones. Significant differences in CPUE among years were detected only in North Carolina and Louisiana.
