Abstract
    In 1982, a survey was initiated to obtain daily catch and effort data on fishes commonly caught by charterboats in the southeastern United States. Boat effort and king mackerel, Scomberonmorus cavalla, CPUE data obtained from 1982 through 1985 were analyzed. The offshore fishing zone (> 10 fathoms) received the highest amount of trolling and other fishing (nontrolling) 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. Data to evaluate seasonal fluctuations in fishing effort were provided for 15 areas of the southeastern United States and for the U.S. Caribbean. Annual CPUE of king mackerel by other fishing was much lower than trolling for most areas and years. CPUE was higher in the nearshore or offshore zone than in the estuarine zone for all area-year combinations except North Carolina in 1983. CPUE values were highest in the nearshore zone about as often as in the offshore zone. Highest CPUE for king mackerel occurred in 1983 or 1985 when all areas were considered. Evaluation of the historical data bases in northwest Florida indicated cyclical patterns of abundance over a 20-year period.
