|Abstract:||Eteline snappers are an important component of commercial
demersal fisheries in the central and western Pacific, but there is a substantial
gap in the knowledge of their life histories, specifically the larval and juvenile
stages. Juvenile pink snapper, Pristipomoides filamentosus (Valenciennes), ranging
in size from 7 to 25 cm fork length, inhabit a nearly featureless plain offshore
of Kane'ohe Bay, O'ahu, at depths of 65-100 m. Bottom samples and
underwater video footage showed the bottom to be uniformly composed of fine,
silty sand with little relief. Conductivity-temperature-depth data indicate that
an internal tide brings cold water over the bottom on a tidal basis. Telemetric
studies show that juveniles undergo small-scale crepuscular migrations from
deeper daytime locations to shallower nighttime locations but move relatively
little during day and night periods. Analysis of length frequency distributions
obtained over a 17-month period resulted in an estimate of the von Bertalanffy
growth constant (K) of 0.21 yr-l.
