The cobia (Rachycentron cannadum) is an aquatic species broadly distributed in the tropical, subtropical and temperate waters of the Atlantic and Indo-Pacific, and until recently absent from the eastern Pacific. By October of 2015, the first specimens were captured in the Colombian Pacific and by November of 2015, the first specimen in waters of the Gulf of Panama was sighted at about 8 Km from the coast (8° 9’ 37.19’’ N, 80° 19’ 28.49’’ W). The specimen was captured at 30m depth using 7.60 cm mesh size gill nets. The fish caught was a 61.5 cm in total length female in its initial phase of gonadal development. This report for the Panamanian Pacific, creates the challenge of following up on the progress of this species into other areas of the Tropical Eastern Pacific.
