Abstract
- The specificity of the species composition of the ichthyofauna in the Russian and Korean waters in the Sea of Japan/East Sea (northwards from 35°17'N) is considered. The population and the proportion of species from the order of the perch-like fishes (Perciformes) steadily decline from the south towards the north; the proportion of the species from the order of the ray-finned fish (Scorpaeniformes) tends to rise. The northward latitudinal gradient in the family composition variability results in a decrease of their numbers along with a significant increase in the sculpins (Cottidae) and the picklebacks (Stichaeidae) in the species composition. In the southernmost region of the studied water area, the sublittoral species tend to prevail; in all of the others, the elittoral species are predominant. The four northern areas are characterized by a high similarity in the species composition (81.8%); this value is significantly lower (63.1%) in case of their comparison with the more southern areas. The similarity in the ichthyofauna composition between the southernmost area and the other studied water area comprises 44.1%. [ABSTRACT FROM AUTHOR]
