Abstract

Animal remains were present in stomach contents of 6 of 13 fish species collected at 10 sites in freshwater streams on Moorea,French Polynesia. The eel Anguilla marmorata contained both freshwater and marine prey, and the eel Anguilla obscuracontained larvae of the pollution-tolerant rat-tailed maggots (Insecta : Diptera : Syrphidae). Fish stomachs contained prey notpreviously collected in these streams. There is clear habitat partitioning between the two most common stream fish. The spottedflagtail, Eleotris fusca, feeds benthically and stomachs contains large numbers of neritid and thiarid snails. The sleeper, Kuhliamarginata, feeds primarily on surface drift, with ants being the most common prey item. The freshwater fish of Moorea havefew parasites relative to those found in Hawaiian Island stream fishes.
