The population dynamics of coral reef fishes may be affected by processes acting either on the larvae in the plankton, on the juveniles and adults on the reef, or both. The relative importance of events occurring during the pre-settlement and post-settlement stages has been the subject of much debate in the coral reef fish literature over the past few years. While some workers think that the dynamics of coral reef fish populations are determined primarily by processes acting on the reef, others believe that variation in larval availability is of more significance. Recently, however, it is being recognized that processes occurring during both stages may be important. In this thesis, I examine the effects of abiotic and biotic factors on the early life history of the ocean surgeonfish, Acanthurus bahianus. Evidence that settlement and early post-settlement persistence are mediated by both habitat and other reef residents suggests that larval supply alone is unable to account for the dynamics of local ocean surgeonfish populations.
