A new nuclear DNA marker is described to identify Atlantic salmon, brown trout, and their hybrids. Species‐specific banding patterns are obtained by digestion of genomic DNA with the restriction endonuclease Sac I and hybridization with a histone DNA probe. FISH analyses in hybrid metaphases illustrate the potential of interspecific hybrids for evolutionary studies.
