Samples of blood, eye, heart, liver and skeletal muscle from 80 specimens of Atlantic cod ( Gadus morhua L.) collected from a restricted area of Trondheimsfjorden, Norway, were examined electro‐phoretically. Analyses of 20 proteins resolved 38 loci, 30 of which were considered potentially useful for population genetic surveys. We describe the electrophoretic expression and tissue predominance of these loci. The proportion of polymorphic loci (0.99 criterion) was 0.30 and average heterozygosity 0.082 ± 0.029.
