Stock discrimination of horse mackerel (Trachurus trachurus) in the Northeast Atlantic and Mediterranean Sea: integrating the results from different stock identification approaches
The goal of horse mackerel stock discrimination was tackled by integrating both established and innovative approaches such as genetic markers (allozymes, mtDNA, microsatellite DNA and SSCP), morphometry and parasites, tagging experiments and life history traits (growth, reproduction and distribution...

The results from genetic approaches (Multilocus Allozyme Electrophoresis, mtDNA and microsatellite DNA) showed that there was only slight genetic differentiation among sampling sites. Another genetic technique (SSCP), was successful in finding a genetic marker that demonstrated substructuring in horse mackerel populations. Several approaches (SSCP, morphometrics, parasites) support the separation between the Atlantic Ocean and the Mediterranean Sea in horse mackerel populations, although the most western Mediterranean area could also be connected with the Atlantic populations.
