(from introduction): In this study, we explored the effects of coral bleaching on the redfin butterflyfish, Chaetodon lunulatus Quoy and Gaimard 1824. This species is distributed throughout the Indo-Pacific Archipelago and eastern Pacific Ocean (Allen et al. 1998), and is among the most abundant butterflyfish species on reefs within this region (e.g., Anderson et al. 1981; Bouchan-Navaro et al. 1985). Previous studies have shown that Chaetodon lunulatus feeds exclusively on living tissues from scleractinian corals (Harmelin-Vivien and Bouchan-Navaro 1983), and is likely therefore, to be very susceptible to changes in the availability of scleractinian corals (Kokita and Nakazono 2001). The purpose of this study was to investigate changes in the (1) abundance, (2) dietary habits (specifically, the proportional consumption of different prey corals), and (3) physiological condition of C. lunulatus, during a major episode of coral bleaching. The specific effects of coral bleaching on C. lunulatus were investigated over a 2-year period (May 2000 to March 2002), on the Great Barrier Reef (GBR), Australia. During this period, the GBR was subject to the most severe episode of coral bleaching ever recorded (Dennis 2002).
