Summary. The human minisatellite probes 33‐6 and 33‐15 cross‐hybridized to DNA digests of Atlantic salmon, brown trout and rainbow trout revealing complex multi‐banded patterns. These DNA fingerprints (in excess of 40 resolvable fragments in some cases) were highly polymorphic, individual specific and found to be stable, both somatically and in the germline. Pedigree analysis of an Atlantic salmon family confirmed that the minisatellite fragments showed Mendelian inheritance. With only a single occurrence of linkage and allelism being observed it is likely the minisatellite loci are widely distributed throughout the salmonid genome. The potential applications for both multi‐ and single locus minisatellite probes in salmonid research are discussed.
