Integration of DNA barcoding for the initial recordings of Lessepsian fishes: a case study of the Indo-Pacific slender ponyfish Equulites elongatus

In this study, the DNA barcode of a regional Lessepsian sighting of the slender ponyfish Equulites elongatus is integrated with morphometric and meristic descriptors as a case study to address further identification problems in the Mediterranean Sea. The study also aims to contribute to the regional mitochondrial cytochrome oxidase I information pool, to support other potential uses. The initial sighting of E. elongatus from the north-eastern Mediterranean coast of Turkey is provided from a trawl survey on 3 June 2015, where 76 specimens were captured during a 15 min tow.
