Fishes in the family Carangidae, currently 147 species recognized worldwide, are commercially important representing high-value products. Their economic importance is also acknowledged in Thailand as the fishes are widely used and commonly found in markets. Unfortunately, few studies focus on the diversity of this family in Thailand. We performed a literature search on any studies of the family Carangidae in Thailand in the databases of Department of Fisheries (E-Library Department of Fisheries) and Department of Marine and Coastal Resources data center (DMCR data center) using genus names and Thai common names as keywords. We also explored SCOPUS database as well as the genetic records of carangid samples collected in Thailand in GenBank. In addition, we sequenced fragments of COI gene that served as DNA barcode of common carangid species obtained from five fish markets around the upper Gulf of Thailand and compared the results with GenBank records. The literature search revealed only 27 studies from Thai government databases and 25 articles from SCOPUS from 1960 to present. Variations in topics of studies on this family were limited to a few species. There were 52 species recorded in Thailand based on an article published in 2011. Since then, scientific names of some genera and species have been revised recently but not updated in Thai databases. Data on genetic diversity of carangid species in Thailand were even scarce as only information on three species, Atule mate, Megalaspis cordyla, and Selar crumenophthalmus were published in GenBank database. Our DNA barcoding results were based on only a small sample size revealed new haplotypes never reported, representing hidden genetic diversity awaiting discovery. These findings indicate vast opportunities for research on diversity of carangid fishes in Thailand
