چکیده

Data of bottom trawl surveys at southwestern Sakhalin and the herring spawning grounds southern Kuril Islands are summarized, with assessment size eggs density in clutches. Fishery statistics media reports overviewed, as well. The stock Sakhalin-Hokkaido population increases since 2015, both off southeastern coasts Sakhalin, Aniva Bay, Islands. Number everywhere within Russian waters, well laying. In particular, biomass was estimated 2020 35.5 . 103 t 62.5 Sakhalin; it 21.6 Bay 2021; total catch waters Island reached 8.3 2021. is restoring after long depression, so this species capable to return list major objects for fishery Sakhalin- region Russia.

To further elucidate the migration history of the brown bears (Ursus arctos) on Hokkaido Island, Japan, we analyzed the complete mitochondrial DNA (mtDNA) sequences of 35 brown bears from Hokkaido, the southern Kuril Islands (Etorofu and Kunashiri), Sakhalin Island, and the Eurasian Continent (continental Russia, Bulgaria, and Tibet), and those of four polar bears. Based on these sequences, we ...

Current State of Art in Earthquake Prediction, Typical Precursors and Experience in Earthquake Forecasting at Sakhalin Island and Surrounding Areas

Despite of over a century of scientific effort, the understanding in earthquake forecasting remains immature. Moreover, even the theoretical possibility of earthquake forecasting is debatable. Especially problematic is a possibility of an effective shortand intermediate-term earthquake forecasting. The aim of this paper is to present the new evidence in support of possibility of the shortand in...

Effects of Pleistocene climatic fluctuations on the phylogeographic and demographic histories of Pacific herring (Clupea pallasii).

We gathered mitochondrial DNA sequences (557 bp from the control region in 935 specimens and 668 bp of the cytochrome b gene in 139 specimens) of Pacific herring collected from 20 nearshore localities spanning the species' extensive range along the North Pacific coastlines of Asia and North America. Haplotype diversity and nucleotide diversity were high, and three major phylogeographic lineages...

Possible Causes and Effects of Shifts in Trends of Abundance in Pink Salmon of Southern Sakhalin and Iturup Islands

Data on the abundance of spawning pink salmon (Oncorhynchus gorbuscha) are presented for rivers of southern Sakhalin Island and Iturup Island. Fluctuations in abundance are more dependent on marine survival than on the abundance of fry migrating downstream. This is explained by the favorable spawning conditions in small rivers with dense aggregations on the spawning grounds. We found stable lon...
