Abstract:

Postlarval gag, Mycleroperca microlepis, collected with fixed neuston nets at Price Inlet, South Carolina, entered the barrier island inlet during late spring-early summer. The mean age of M. microlepis collected during 5 years of sampling was 43 days; mean standard length was 15 mm. Postlarvae were most abundant in near-surface waters during night flood tides and generally did not leave the inlet on subsequent ebb tides. Analysis of back-calculated fertilization dates, as determined from presumed daily growth increments in lapilli from postlarvae, indicated that putative peaks in spawning were correlated with lunar phase. Estimates of the magnitude of ingress and the extremely rare occurrence of young of the year offshore suggest that estuarine ingress and residence is probably a consistent and integral part of the early life history of M. microlepis off South Carolina.
