Reef Þshes migrate for reproductive purposes (Shibuno
et al. 1993; Warner 1995; Aguilar-Perera and Aguilar-
Da« vila 1996), and there was at least one species (Chromis
viridis) in this study which displayed such behaviour.
Ontogenetic habitat shifts also take place (Itzkowitz 1985;
Lirman 1994; Eggleston 1995; McGehee 1995), and there
were numerous species in this study which did not settle
on the study bommies, but which arrived as juveniles 4Ð6weeks after settlement (personal observation). Some larger
species had home ranges which incorporated several
patch reefs, so that individuals were often seen intermittently
on the same bommies. In these cases, interpatch
migration occurred as part of regular foraging activities
(e.g. Ogden and Buckman 1973; Noda et al. 1994). While
there have been no previous studies of post-recruit immigration
in diverse reef Þsh assemblages, there is abundant
evidence of movement capabilities. Within-reef movements
of post-recruit Þshes have been speciÞcally
documented in Epinephelus striatus (Aguilar-Perera and
Aguilar-Da« vila 1996) Amphiprion clarkii (Hattori 1995),
Chromis chrysurus (Noda et al. 1994), Mulloides
ßavolineatus (Holland et al. 1993), Halichoeres marginatus
(Shibuno et al. 1993), Acanthurus bahainus, A. chirugus,
and A. coeruleus (Robertson 1988; Sweatman and Robertson
1994), Stegastes leucostictus (Itzkowitz 1985), and
Scarus croicensis (Ogden and Buckman 1973). There were
ancillary reports of migration in Dascyllus marginatus
(Liberman et al. 1995), Pomacentrus australis (Brothers
et al. 1983), Pomacentrus wardi (Sale 1979), and Chromis
atripectoralis (Williams et al. 1994), while numerous
authors have reported migration in a range of species
during the course of assemblage level studies (see Molles
1978; Brock et al. 1979; Ogden and Ebersole 1981, Lassig
1983; Sweatman 1985; Walsh 1985; Doherty and Sale
1985; Baelde 1990; Caley 1993)
