Abstract

Over-exploitation of traditional coastal stocks and a rising demand for seafood have resulted in the shift of commercial fishing towards less-known, deep-sea species in many parts of the world. Yet, the lack of knowledge of the biology, ecology and life-history of these species represents a serious impediment for establishing sound stock management plans. With the aim of providing tools that will allow assessment of the population genetic structure of Macrourus berglax, we have isolated and characterised a suite of novel microsatellite loci for this deep sea grenadier. Eight of these markers showed between 4 and 11 alleles per locus in two distant North Atlantic populations, with observed and expected heterozygosities between 0.17-0.83 and 0.35-0.87, respectively. Importantly, eight of these loci also cross-amplify in other Macrourid species.
