Synopsis Fish collections from 19 tidepools on a rock plateau at Martins Bay, on the east coast of Barbados, taken on three occasions (1981,1983 and 1987) contained 2078 individuals of 63 species. The number of species, individuals and total biomass increased with pool size. Partial residents, primarily juveniles of reef species, comprised 44% of species, 36% of numbers, and 26% of biomass. True and partial residents were of similar sizes. Most of the latter grow to larger sizes than those observed in the pools, indicating that the use of tidepools by fishes is size-dependent. Species richness, numbers of individuals and biomass in individual pools was positively associated with pool size. These relationships did not vary among sampling occasions. Species composition and relative abundance was also found to be similar among sampling occasions, leading to the conclusion that the tidepool assemblages are resilient and stable.
