Abstract:

The authors address demographic and economic problems in the Sakhalin Region, which is an island region, the only one of its kind in Russia. The Sakhalin Region includes the island of Sakhalin, the islands of Moneron and Tyuleniy, and the Kuril Islands. The area of the Sakhalin Region is 87.1 thousand km2, including the largest territorial part on the island of Sakhalin, whose area is 78 thousand km2. The unemployment rate on Sakhalin, as well as the effectiveness of measures taken by the local administration and the state to reduce it are analyzed.

Spatial distribution of pacific herring Clupea pallasii in the Okhotsk Sea waters at the northeastern coast of Sakhalin Island is described on the data of surveys conducted in June-October of 1989 and 1997-2020 using bottom and midwater trawls and Danish seine. The herring distribute widely, with the main aggregations in the area with depth up to 100 m between the Lunsky Bay and Piltun Bay. These aggregations are formed by the native herring of the North-East Sakhalin population, whereas the herring in the deeper waters belong to the Okhotsk population.

Regular deepening of the thermocline/halocline has prevented the rise of cold and salt water to the sea surface.
