Genetic markers for identification of fish eggs

We have developed genetic markers for accurate identification of the early stage eggs of Atlantic horse-mackerel, Mediterranean horse-mackerel, blue jack mackerel, snipe fish, mackerel, Spanish mackerel, cod, haddock, whiting, hake, common megrim and four-dotted megrim. The results will be employed for stock assessment of these species.

We have disseminated this result in International Symposia (ICES Congress 2002, 4th World Fisheries Congress, AFS Symposium 2004 and others). It will be published in peer-reviewed scientific journals. It has also been communicated to different ICES work groups. The main innovation is to obtain unambiguous genetic results from formalin-fixed eggs allowing a perfect identification of the target species.

The expected benefits are mainly related to a sustainable management of the target species.

Application: Fisheries management.
