Most coral reef fish have a bipartite life-history characterized by a pelaglc larval phase followed by transformation and settlr~rlent into a benthic existence There is inci-eas~ng Interest anlong marine ecologists in determining thc importance of post-settlement processes to reef f ~ s h demography. This study distinguishes movement as an important post-settlement phenomenon affecting estimates of early survivorship of juvenile coral reef fishes. Individuals settling onto artificial patch habitats were collected, marked, released and monitored by visual census over 2 systems of ~sola ted artificial patch habitats. Some recently settled juvenile fish moved as much as 100 m over open sand. Probability of movement was dependent on species; size was a significant factor among species, but not among conspecifics. Survlvorship calculated from observations of uniquely marked indiv~duals was contrasted with survivorsh~p estimated by comparing the initial number of newly settled indiv~duals at a site with the number of indiv~duals there after a given time interval. The comparison revealed that new settlers and immigrants can mask the loss of individuals included in the original census and thereby ~nf la te stimates of survivorship. Coinparing survival estimates with and without accounting for movement demonstrated that survivorship can be underestimated when new settlers subsequently emigrate and survive at another site, but are unwittingly recorded as lost due to mortal~ty. Significant differences were observed in survival experiences for different species and size classes. Where significant differences were found in sur\iival times of mob~le individuals versus sedentary, those that moved survived longer.
