Fig. 12.15 In Palau at one multi-species aggregation site underwater surveys recorded elevated
numbers of Plectropomus areolatus ( black bar ), Epinephelus fuscoguttatus (white bar ) and
E. polyphekadion ( dashed bar ) between April and September 2009 with P. areolatus attaining
about 460 individuals and showing elevated numbers for more months than the other two species;
aggregations do not form in other months (Source: Palau Conservation Society 2010 )
