Location of sampling sites (open circles = handline fishing; dark circles dives; stars = rotenone). Results and discussion A checklist, totaling 653 taxa distributed among 72 families, is presented in Table 1. There are about 300 fewer species known from Ouvea than from nearby New Caledonia, where more than 950 reef-fish species have been recorded (Rivaton et al., 1989). The number of taxa known from Ouvea is closer to the 795 species recorded from the Chesterfield archipelago (Kulbicki et al., 1994), another isolated area at a similar latitude, than to the 425 species recorded from Rotuma (Zug et al., 1989), a small cluster of islands about 450 km north of the Fiji Islands. Because our sampling (only 13 rotenone stations) at Ouvea is limited and we have not sampled the eastern side of the atoll, we believe the total number of shorefish species may actually be as high as 800-900 Please note that
