Abstract: Three coral reef surgeonfishes (Acanthurus guttatus, A. triostegus,
A. lineatus) and two wrasses (Thalassoma quinquevittatum, T. hardwickii)
spawned year-round in American Samoa. Spawning occurred in or adjacent
to the channel draining the fringing reef at specific times of day: dawn (A.
lineatus), daytime (T quinquevittatum, T hardwickii), or dusk (A. guttatus, A.
triostegus); and spawning time tracked seasonal changes in day length. Egg
predation was high for the surgeonfishes, but predation by piscivores appeared
to be low.
