N2 - Chromosomal sets of the White Sea herring (Clupea pallasi marisalbi, Berg) were studied to resolve the problem of its population structure. Adults, larvae and embryos were analyzed. It was found that populations from different locations differ in frequency of Robertsonian rearrangement (2n = 52, 51, 50; NF = 60). Frequency of rearrangement increases from north-west (0.000-0.005) to south-east (0.133) of the White Sea. Chromosomal differences between fast- and slow-growing herring have not been found. According to karyological data, the White Sea herring subspecies can be considered as a group of populations of Pacific origin with only a poor gene flow between them.
