Mitochondrial DNA and allozyme variation in Atlantic salmon (Salmo salar) populations in Wales
1995

Four restriction enzymes were used to assay mitochondrial DNA (mtDNA) variation in Atlantic salmon (Salmo salar) in Wales. A total of 122 fish from 22 sites, within three catchments, were analyzed. A further 368 fish from seven of these sites were also investigated at 19–21 allozyme loci. The allozyme and mtDNA data revealed significant genetic differentiation between and within catchments. The allozyme data were as informative as mtDNA restriction fragment length polymorphisms in distinguishing between populations of Atlantic salmon. The similarity between data sets in information content is in contrast with previous studies. The relative value of both techniques to fishery managers is discussed.
