Abstract: Larvae of 72 taxa of nearshore fishes were identified from midwater
trawl samples taken in oceanic waters between Hawai'i and Tahiti.
Catches of nearshore fish larvae and number of taxa caught declined with distance
from the closest island. Most of the taxa were taken only within 300 km
of the nearest island; only eight taxa were taken more than twice at greater
distances. Highest catches were at stations close to major island groups, the
Hawaiian or Society islands. Among stations closest to small isolated islands,
densities were higher relative to distance from shore within the North Equatorial
Countercurrent and the Equatorial Undercurrent; these strong eastward-
flowing currents routinely transport larvae > 1000 km from likely sources
upstream. Even in the zones of higher abundance, densities of nearshore larvae
were much lower than in coastal waters, and adequate sampling in oceanic
waters requires larger, faster nets than those typically used for ichthyoplankton
studies.
