Abstract
Levels of variation at six VNTR (variable number of tandem repeats) loci, one minisatellite and five microsatellite loci, isolated from tri‐ and tetranucleotide enriched DNA libraries for northern pike were generally low in two Danish populations (1–4 alleles; expected heterozygosity 0–0·57), though one highly variable microsatellite (13 alleles; expected heterozygosity 0·79) was identified. In combination with previously published microsatellites a set consisting of nine polymorphic loci appeared to be useful for discriminating populations, as determined by assignment tests.
