Protein electrophoresis was used to examine genetic variability in three stream populations of the freshwater goby, Lentipes concolor, a Category 1 candidate for listing as endangered or threatened. A survey of 31 presumptive genetic Ioci for fish on Hawaii and Kauai, the two most widely separated Hawaiian islands supporting freshwater gobies, indicated no apparent depression of genetic variability and no appreciable genetic differences between fish from the same or different islands. These data are compatible with the hypothesis that sea-surface current gyres distribute genetically similar planktonic larvae throughout the Hawaiian Islands.
