Background: The fishes of the family Carangidae forms one of the largest families of bony fishes, representing about 140 species, widely distributed in all tropical and temperate marine waters of the world. In recent past, fishes of this family are exhibiting new geographical distribution which could be attributed to climatic variability. Methods: The specimens were collected from multiday trawl boats operated along Karnataka coast. Morphometric and meristic characteristics together with genetic analysis using DNA bar coding was used to validate the identity of the specimen. Spatial distribution map of the species in Indian Ocean was generated using the information from the present study and available literature. Result: The morphometric and meristic characteristics of the specimens of greater amberjack, Seriola dumerili collected during the study were comparable with the previous investigations. The phylogenetic tree constructed using sequences of COI (MW974826 and MW974827) of the Seriola species showed distinct clustering among species with significant bootstrap values confirming the identity to the extent of 99% with the sequences of Seriola dumerili deposited in NCBI GenBank. This study confirms the first distributional record of Seriola dumerili from the eastern Arabian Sea.
