Aquaculture paper

Another day, another paper. Sušnik et al. paper was published as a technical note in Aquaculture (2008, 285, 260-263), A set of nuclear DNA markers diagnostic for marble trout, Salmo marmoratus.

One of the main problem from the native range of marble trout is hybridisation with non native brown trout (Salmo trutta). It is not always easy to distinguish marble trout from brown trout (or from marble × brown trout hybrids) by appearance especially after a successful decade of repopulation project. Mitochondrial DNA and microsatellite markers have their limitations (maternal inheritance for the first, overlapping alleles for the later) so another set of nuclear markers was urgently needed. Markers from this paper were used exactly one year ago and that means that the 2008 results from hybrid zone will be available in a few days.
