Videogrammetry data taken in 2007 are used for a study of fish within coral reef ecosystems. We attempted to generate or find information on abundance, growth, sex-specific size-at-maturity, length-specific sex ratios, size-fecundity relationships, age structure, and forces of mortality for three exploited reef fishes (Centropyge potteri, Dascyllus albisella, and Parupeneus multifasciatus). This project included a novel approach to the study of reef fish biology: Estimation of mortality rates inside and outside a no-take marine reserve allowed fishery-independent estimation of natural and fishing mortality. Primary sites are Hanauma Bay, a reserve, and Maunalua Bay, an open fishing area nearby.
These data support fisheries management decisions.
