Fig. 2.6 Multiple-species spawning aggregation sites showing outer limits of spawning aggregation
areas of camoufl age grouper, ( Epinephelus polyphekadion ), brown-marbled grouper ( E. fuscoguttatus )
and squaretail coralgrouper ( P. areolatus ) in two channels in Palau on a single day. Channel A is
broad (400 m) and deep (>30 m) while Channel B has a narrow mouth (50 m wide) and shallow
(12 m). In Channel A the three groupers have space to occupy their preferred bottom type and
depth while in Channel B they are more confi ned and have strongly overlapping distributions. The
outer limits of aggregations can change day to day due to changes in numbers of fi shes present
