Introduction of non-native species threatens the life of many aquatic organisms. Successful eradication efforts of non-native species include early detection, but currently no traditional monitoring techniques have been successful. New approaches using environmental DNA (eDNA) are beginning to be used as a complement for traditional monitoring methods. We tested the efficacy of eDNA methods for detecting alligator gar in an artificial pond in Depok, Indonesia. Water samples (200 mL) were collected and filtered through a 0.45 nitrate cellulose filter. The results show that eDNA was detected in three out of four samples throughout the 1-month study period. We found that eDNA from alligator gar can be detected using water samples and should be considered as a complementary method to traditional sampling approaches. Further studies are necessary to employ eDNA detection of alligator gar in the field.
