Variability of Morphobiological Characteristics of the Pacific Herring Clupea pallasii from Arctic and Pacific Populations
JOURNAL OF ICHTHYOLOGY(2021)
Abstract
A comparative analysis of the biological and morphometric characteristics of the Pacific herring Clupea pallasii from different parts of the range, from the White Sea to the Yellow Sea, was performed. Forming of the modern species range, covering the waters of the Arctic, boreal, and subtropical zoogeographic zones, was preconditioned by the system of adaptations developed during the long evolution in the specific conditions of the northern Pacific Ocean. The results of multivariate discriminant analysis indicated relatively small differences in the complex of meristic features when comparing the samples from the Pacific Ocean and the samples obtained in the Arctic Ocean and the north-eastern Atlantic Ocean.
