The reproductive behavior of Acanthurus nigrofuscus, a common surgeonfish of the Red Sea, is described for two overlapping populations inhabiting the coral reefs off Eilat, Israel (Gulf of Aqaba). The spectacular daily spawning activities, often involving aggregations of thousands of individuals, as well as the often long distance migrations to and from the spawning grounds by groups in highly organized formations are characterized in detail. Evidence is provided that the precise timing of these various phenomena is controlled by ambient light levels during the late afternoon. Less detailed information is also provided on comparable activities of two other surgeonfishes from the same reefs: Ctenochaetus striatus and Zebrasoma xanthurum. Finally, comparisons are made of reproduction and its associated environmental controls among populations of the same and related species of surgeonfishes at widely distributed locations in the Indo‐Pacific. 1988 Blackwell Verlag GmbH
