Article Description

Courtship and spawning are described for Pomacanthus imperator and 4 Centropyge spp. at Enewetak Atoll, Marshall Islands, observed from 15 August to 15 September, 1981. In all species, courtship and spawning occur at dusk, continue throughout most of the lunar month, are preceded by male display to the female, and culminate in the pair's shedding gametes into the water column. The species differ in ascent height, details of courtship behavior, spawning location relative to prominent reef topography and degree and type of sexual dichromatism. Social organization in all species appears based on male defense of harems of 2 to 5 females. Observed behavior is compared to that of confamilials, and discussed relative to proposed theories concerning lunar periodicity of spawning activity, sexual dichromatism and the adaptive significance of spawning ascent behavior. © 1982 Springer-Verlag.
