The first data are presented about the Sciomyzidae of Iturup, the largest of the Kuril Islands. A total of ten species are recorded. Limnia setosa Yano is recorded for the first time from Russia; Tetanocera montana Day and T. phyllophora Melander are recorded for the first time from the Kuril Islands. Photographs, comments on diagnostic characters and adult habitats of poorly known species are given.

The paper analyzes the long-term dynamics of stocks and annual catches of Pacific cod of the Kuril Islands, and also considers the structure of its modern fishery, taking into account the changes that have occurred in the organization of its coastal fishing in recent years. It was shown that the dynamics of commercial biomass of Pacific cod in the Northern and Southern Kuril Islands is comparable to that in 1975-2020 for groups in the southeastern part of the Bering Sea, the Karagin and Olyutor bays, on the shelf of Western Kamchatka, and in south-western Sakhalin. Development of the cod fishery in the North and South Kuril Islands in 1980-2019 went in accordance with the dynamics of stocks, the maximum catches were observed during the period of a high level of abundance of both groups in the 1980s. While the structure of the cod fishery on the shelf of the Northern Kuril Islands to date can be considered established, the development of fishing in the South Kuril Islands in the last two decades went by the gradual replacement of trawl fishing in the winter-spring period with snorkeling in the summer season.

The materials of satellite observations of the sea surface temperature in the study area (1998–2020) were also analyzed by statistical methods and by decomposition according to the EOF. The amplitude of the averaged curve of the annual variation of the ocean surface temperature (SST) as a whole for the region was estimated, which was 7° (the contribution of the semiannual component with an amplitude of 1°С is small), as well as the most significant anomalies that reached 4°С in cold August 2002 and 3°С in warm September 2012. A quasiperiodic course of the envelope of summer maximums with a period of 5–6 years was revealed. It is shown that there is negligible trend in the thermal regime in the study area. Based on the analysis of materials from 10 oceanological surveys, seasonal variations in hydrological conditions in the area of South Kuril Islands were studied. It is shown that the areas of the Kunashirsky and Yuzhno-Kurilsky Straits in the warm season are filled with warm and salty waters of the Soya Current, and in winter and spring - with freshened modified water from the Amur River runoff transported by the East Sakhalin Current. Annual salinity variations exceed 1.5 psu here.

Storm surges (the significant sea level rises due to a drop in surface atmospheric pressure and an increase in wind velocity during the passage of deep cyclones over the coastal areas) pose a formidable threat to the coastal settlements of Sakhalin and the South Kuril Islands. As a result of flooding of coastal areas, the impact of storm waves on the shores and coastal facilities is sharply increased. The greatest damage caused by surges on 10.11.1990 and 9.11.1995 which affected the most populated southern part of Sakhalin Island. A long-term sea level series were analyzed, recorded at 9 coastal tide gauges located on the coast of Sakhalin Island and South Kuril Islands. Estimates for the maximum heights of the storm surges and tidal level were obtained separately, as well as for the rare recurrence of the total sea level height with the probability of these individual components superposition. The maximum total height of the sea level was obtained for the Kurilsk station, where the highest storm surge was recorded. The minimum values were obtained for southwestern coast of Sakhalin Island (Kholmsk and Nevelsk stations) were tides are small. Seasonal and inter-annual variations of strong waves were analysed from the data of visual observations.
