摘要

An evaluation of marks on scales, otoliths, vertebrae, and dorsal and anal fin rays for age determination of pompano, ladyfish, crevalle jack, gulf flounder, and southern flounder was performed. Otoliths were selected as the most suitable age-determination structure. Otolith radii and marks had high positive correlations with fork lengths for pompano, ladyfish, and crevalle jack, and with total length for gulf flounder and southern flounder.
