dc.descriptionWhitebone porgy, Calamus leucosteus, were taken in trawl surveys over reef and non reef habitats in the South Atlantic Bight in depths of 11 to 88 m. Larger individuals were taken in greater depths. Twelve age groups can be identified with sectioned otoliths and nine using scales. Annulus formation for otoliths and scales occurs between June and July. Von Bertalanffy growth equations of Lt = 331 [1 - e-O.173' ,..,.6390IJ from otoliths and Lt = 362 [ 1- e-O.261111.0.3973] from scales suggest that attainment of maximum size for this species is similar to reports for other reef species. The fork length-weight relationship for C. leucosteus can be described by W= 0~00004 FL'·90? The whitebone porgy is a protogynous hermaphrodite; younger, smaller fish are predominately females, and older, large fish are mostly males. Sexual transition most commonly occurs between ages II-IV and fork lengths 18-25 em. Peak spawning occurs in May with total fecundity ranging from 30,400 to 1,587,400 eggs. The fecundity-weight relationship can be described by F = 10.29438 WI.6562. Regional landings data are not available for C. leucosteus; however, it was the third and fourth most abundant species by weight from trawler landings in South Carolina during 1979 and 1980.
