Abstract: This study aims to describe and obtain the morpho-species character and phylogenetic of the trevally caught within Malluccas sea of Indonesia based on morphological and genetic. Morphological characters determination is using 18 truss morphometrics of 200 fish samples, genetic analysis is using 4 individual. The morphometric measurements use a 0.01 mm-scale digital caliper. Principal Component Analysis (PCA), Hierarchy Cluster Analysis (HCA) and Anova K-means Cluster (AKmC) were used to describe morphological grouping of fish, aligning DNA-COI sequences used for genetic confirmation. Results of PCA, HCA and AKmC indicate that there are four types of scads captured in Bitung waters with local names of Small Eye Travelly (SET), Big Eye Travelly (BET), Stone Travelly (ST) and Yellow Tail Travelly (YTT) where each has a different morphological character. There are twelve different morphological characters and six not different characters. The DNA-COI sequence alignment results indicate that SET and BET have 99.8% similarity with each other and belong to the same species namely Selar crumenophthalmus. ST is a Selar boops species with 98% similarity and YTT is a Selaroides leptolepis species with 98% similarity.
