The characteristics of four soils of the Kamchatka Peninsula that are mostly needed protection are presented in the article. Reference plots have been allocated for two of them, which are proposed for inclusion in the Red Book of Soils of Russia. Their morphology is described; photos of soil profiles, cartographies of their location are given. One of the sites characterizes ochre typical soil which is zonal for the region, the other – a rare soil on diatomite deposits. A plot located in the area of the village Sosnovka (Yelizovsky district) which earlier was the basis for the most complete description of the first soil was proposed as a reference for it. The reference for the second soil is a small relief lowering, located at the southern tip of Sredinny Range in the valley of the Plotnikov River, representing the only location of this soil on the peninsula. Each site proposed for protection is recommended to be given the protected status of a ‟Natural monument” of regional significance.

The study was conducted in June – July 2016 and 2021 on the southeastern coast of Kamchatka. Birds on line transects and on routes along the coastline were taken into account from the side of a small vessel (boat) and on a motor boat. We recorded 32 bird species, mainly alcids (34.4% of the species composition), larids (15.6%) and anatids (12.5%). The density of bird distribution in the water area was 25.5 individuals/km2 on average. In terms of numbers, the tubenoses and alcids (42.9% each) occupied the dominant position on the accounting transects remote from the land, and on the routes close to the shore – larids (61.5%) and alcids (23.0%). The total number of birds within the boundaries of the coastal water area of 1 280 km2 is approximately 40 thousand individuals. The basis of the population (about 60%) consists of eight species nesting in this area, each of which has more than 1 000 individuals (mainly tufted puffins and murres). The remaining 40% are species from other regions (short-tailed shearwaters migrating from the southern hemisphere, northern fulmars nesting on the neighboring territories and phalaropes during postnesting migrations).

A comparative study of cultural and biochemical parameters of two microalgal species, Tetraselmis sueciaca and Phaeodactylum tricornutum, was performed. Cell density in the storage culture was 2.88 million cells per one ml for T. sueciaca and 20.37 million cells per one ml for Ph. tricornutum. As shown, determination of op-tical density of the culture medium is a more objective characteristic of the cumulative culture growth. For T. sueciaca, cell growth rate during the course of experiment made 400% and for Ph. tricornutum – 700%. Dif-ference in the chemical composition of microalgal biomass was revealed. The microalgae did not differ in their energy value. The prospects of cumulative culture of microalgae in mariculture farms are discussed.

The results of studies of organoleptic parameters, chemical composition, nutritional and energy value of dried food products from the skin of Pacific and Commander squid, obtained by drying with infrared rays and subsequent grinding were presented in the article. It is shown that the developed product is a highprotein and multicomponent one. A high content of lipids and minerals in dried products has been established. The presence of essential microelements (copper, zinc and manganese) was determined. It has been established that the developed product fully complies with the requirements of regulatory documents in terms of lead and cadmium content. The high organoleptic properties of dried products were shown.

Ensuring reliable and efficient electricity supply of remote energy isolated areas is an urgent task, since any failure in an isolated system leads to dangerous crisis phenomena and significant economic losses. The presented comprehensive assessment of the electric power industry state in the Aleutian isolated power unit makes it possible to predict the prospects for its development within the framework of the electric power complex of the Kamchatka Territory. The issues of optimizing the network infrastructure and generating capacities, ensuring long-term and medium-term demand for electric energy and capacity, creating stable and favorable conditions for attracting investments in the construction of electric power facilities of the Aleutian isolated power unit were considered. The current and prospective balances of electricity and capacity in the Aleutian isolated power unit based on the analysis of the energy structure of an isolated power unit and the electricity demand dynamics were calculated. The options for developing the electricity supply system of the Aleutian power unit were considered.
