Survival, growth, and reproduction of Amphiprion percula in Madang Lagoon, Papua New Guinea

I studied the fitness effects of group living in the clown anemonefish, Amphiprion percula, for 12 months (January 1997 - December 1997), in Madang Lagoon, Papua New Guinea. All fieldwork was conducted using SCUBA at depths of up to 13m, and I conducted a thorough census of the population ever 1-2 days. I studied 97 groups on three reefs: Sinub (reef 1), n = 40; Wongad (reef 2), n = 31; and Masamoz (reef 3), n = 26. Each group occupied a single anemone (Heteractis magnifica). Groups consisted of a breeding pair and zero to four non-breeders (mean number of individuals in each group ý s.d. = 3.4 ý 0.9, n = 97).
