Özet
Two sets of phenotypic markers, otolith shape and meristics, were used to investigate the morphological structure of herring populations of the North-East Atlantic and to test the application of the truss method on otolith shape to discriminate between the populations. Otolith and meristic analyses displayed similar patterns of differentiation between the herring populations, revealing a discreteness of the Icelandic summer spawners, Trondheimsfjord herring, Baltic herring and the British Isles groups. The pattern of phenotypic discreteness detected with meristics and analysis of otolith shape suggests a direct relationship between the extent of phenotypic divergence and the geographic separation of the populations, indicating that geographic separation limits migration between the populations.
