Abstract: The Korean spotted barbel (Hemibarbus mylodon), which lives only in Korea, has been threatened to be extinct. This study aims to predict the distribution potential of Korean spotted barbel using MaxEnt (Maximum Entropy Model), with occurrence data recorded from 2012 to 2014 and 17 environmental variables divided into five categories (water quantity, water quality, temperature, precipitation, and topography). The environment variables of spring such as flow rate, air temperature, and precipitation were predicted to have a great influence on the distribution of Korean spotted barbel. In particular, sharp decrease of the probability of presence was identified in the response curve of spring mean flow rate when it was low. The distribution of Korean spotted barbel will be largely reduced under the RCP 8.5 scenario while it will not be significantly affected under RCP4.5 scenario. These findings can be useful for the conservation and restoration of Korean spotted barbel.
