Published: August 2020

Abstract
Industrial development of the Arctic zone of the Russian Federation, climate change, modification of the regulatory and legal framework, large-scale economic transformations taking place both in Russia and around the world have led to serious changes in the traditional economy and traditional way of life of the indigenous peoples of the North. A whole complex of interconnected problems and contradictions has arisen. They require serious study, analysis and development of measures to resolve them. In this work, an attempt is made to identify from the arrays of scientific literature, further generalize and formalize the key problems (challenges) of the indigenous peoples of the North, localized on the land territory of the Russian Arctic. The key challenges of indigenous peoples living in the Yamal-Nenets Autonomous District are formulated. The identity of the problems of indigenous peoples was revealed throughout the territory of the Russian Arctic, which indicates their extra-regional nature. Explanations on the mechanisms of the interdetermination of key problems and the formation of cause-effect relationships in the environment of indigenous peoples are given. Based on the results obtained, nodes and development trends of indigenous peoples that allow predicting the further development of events are formulated.
Dynamics of interethnic mixing in Yamal Nenets people (according to data on the marriage structure and the surname database)
Authors: Lavryashina M B , Ulyanova M V , Poddubikov V V 
Published: August 2020

Abstract
The article discusses the results of the mixation study of Yamal Tundra Nenets people from 1980 to 2019 within the context of their inclusion in inter-ethnic contacts with allochthonous ethnic groups, mechanisms of miscegenation and changes in population genetic structure. Two generations (the 1980s and 2010s) of Tundra Nenets from Yar-Sale rural settlement, Yamal district, YNAD were studied - a total of 8346 Nenets. Dynamics of structure of marriages and surnames were analyzed. Obtained data demonstrates a relatively low level of genetic and demographic transformations accumulated during the studied period. This can be traced, in part, when looking at the frequency of ethnically mixed marriages and the percentage of the new (“alien”) surnames integrated into the Nenets surname structure. We predict a gradual positive dynamic (i.e., increase) of these figures.
Strategy for the sustainable development of indigenous peoples of the Arctic: problems and prospects in the context of new industrial development
Authors: Romanova O D , Romanov P G 
Published: August 2020

Abstract
The depletion of natural mineral resources in traditional places of production entails a gradual shift in the industrial exploitation of new deposits in previously inaccessible northern territories. An example of this is the expansion of hydrocarbon production in the northern seas, the gradual movement of the mining industries of diamonds, tin, gold and other minerals to higher northern latitudes. The development of electronics, the hyperbolic expansion of digitalization all over the world entail a corresponding increase in the consumption of raw materials and materials with unique properties by the electronic industry. In turn, this leads to the search and development of previously inaccessible, economically extremely costly, unique in their locations deposits of rare earth metals. The history of the development of mineral deposits in the northern territories in the former Soviet Union has demonstrated the profound social, environmental and economic consequences of the erroneous approaches of those years. Complexity in the development of the northern territories should consist in taking into account and implementing the social, environmental and economic aspects (directions) of industrial development and preventing their imbalance. Previously, production interests prevailed, mining was carried out in an extremely costly, inefficient, extensive way. The state approach of the Soviet Union consisted in arranging a full-fledged new city or settlement. The economic consequences are also very vast and significant. It turns out that on one territory there are two models: the first is an industrial model, and the second is a model of traditional residence of local residents. The task is to harmonize the interaction of these two models, which actually exist at the present time, and create such new Strategies for the socio-economic development of the regions of the Arctic zone, where this harmonization was originally provided.
Dynamics of distribution of inconnu in the riverbeds depression of the Irtysh River
Authors: Chemagin A A 
Published: August 2020

Abstract
The studies were performed by the hydroacoustic method in the section of the lower reaches of the Irtysh River (Western Siberia, Tyumen Region). The density dynamics of a group of fish with a symmetrical swimming bladder (Coregonidae and Esocidae) in the water areas of the riverbeds depression was studied. Among coregonids, inconnu dominates. The share of this group of fish is in the range of 10-11% of the total density of the fish population, and the density is an average of 0.3 thousand individuals ha1. Fish density has an inverse statistically significant correlation with the water level factor and the inverse correlation with the water temperature. Lower Irtysh is a wintering and feeding section for inconnu individuals; here, inconnu are formed aggregations in river areas called riverbeds depression.
Current state of Atlantic salmon populations in Karelia and updating its farm breeding technologies
Authors: Ilmast N V , Milyanchuk N P , Nemova N N 
Published: August 2020

Abstract
Diadromous marine and freshwater Atlantic salmon occurs in Karelia’s water bodies. Freshwater salmon populations are listed in the Red Data Books of the Russian Federation and the Republic of Karelia. Marine salmon occurs in relatively small Karelia’s rivers flowing into the White Sea. In the past few decades, the deleterious influence of economic activities on North European Russia’s valuable fish stock tends to increase. As a result of hydraulic construction and other types of human activities, the White Sea salmon stock has rapidly decreased. An efficient way of restoring its abundance is “farm” reproduction. In the Republic of Karelia, artificial salmon reproduction is carried out at Vyg and Kem fish farms. One of the methods used to improve fish production quality is to apply laser radiation to salmon eggs and juveniles during “farm” reproduction. Application of low-intensity laser radiation to fish in a certain dose range has been shown to improve the compensatory adaptation of organisms. As a result, death rate declines and fish samples grow more rapidly. To reconstruct and maintain the original structure of Atlantic salmon populations in Karelia’s water bodies, purpose-oriented fish breeding, which comprises farm reproduction, fish protection and the recultivation of spawning and growing grounds, is needed.
Biodegradation of petroleum hydrocarbons by bioflocculant-producing microorganisms of the aquatic ecosystems in the Arctic region

Published: August 2020

Abstract
Currently it is not feasible to completely eliminate the contamination of water bodies with oil, which makes it relevant to perform activities aimed at addressing this environmental challenge. Biological method of cleaning water could be recognized as an effective means of environmental protection. Increasingly, bioremediation uses indigenous microorganisms of specific contamination sites, since these organisms are adapted to the prevailing climatic and environmental conditions, which confers the advantages. Consequently, studies aimed at isolation and selection of the most active microorganisms oxidizing petroleum hydrocarbons and capable of using them are particularly relevant. The aim of this study is the search and selection of effective microorganisms-degraders of petroleum, maximally adapted to the conditions of the Far North. In this study, hydrocarbon-oxidizing features of indigenous bacteria in the Arctic region were examined, and the most effective strains for devising the bioremediation agents were selected. In all strains of bacteria tested that demonstrated steady and intensive growth in the medium with diesel fuel the following characteristics were studied: the percentage of oil degradation in the conditions of laboratory model experiments, the indicator of hydrophobic indicator, and growth potential as well. Strains of microorganisms with the highest degrading ability were selected: A. eucrenophyla, Ps.lundensis, Ps. fragi. These bacterial strains are promising as biodecomposers of hydrocarbons and can be used in bioremediation of environmental contamination. Bacteria from the isolated strains are persistent and dominant components of the natural aquatic ecological communities, thereby the necessity of taking into account the climatic conditions of the region could be avoided.
Structural parameters and infection rate of the genus Littorina (Mollusca: Gastropoda) of the western and eastern Murman coast
Authors: Kulesh K , Kravets P , Bacherikov I 
Published: August 2020

Abstract
There is information obtained on species composition, parasitofauna, and structural characteristics of periwinkles in autumn period in three areas (Abram-Mys settlement, Mishukovo settlement, Retinskaya bay) of western Murman coast, and was made a comparison of data with periwinkles of Eastern Murman. The eastern Murman coast is characterized by 6 species of periwinkles, with 5 species noted on the western Murman coast in this study, because the molluscs Littorina compressa have not been found. The infection rate of males L. saxatilis and L. obtusata in senior size classes of East Murman exceeds the infection rate of females what leads to the difference in the sex structure ratio of molluscs. This fact is also characteristic for periwinkles of Western Murman. Periwinkles of Eastern Murman significantly exceed periwinkles of Western Murman in shell height, shell width, and densities. The difference in maximum age is a one year for L. saxatilis molluscs of Western and Eastern Murman; there is no difference for L. obtusata. Maximum age for L. littorea is 13+, for Eastern Murman is 28+. The dominance of trematodes with a life cycle without a free-standing larval stage and a second intermediate host is typical for periwinkles of Western and Eastern Murman.
The effect of experimental drill fluid on the vital activities of the bivalve mollusk Mytilus edulis L.
Authors: Malavenda S S , Belukhin A I , Bogdanov A O , Bannikov A A 
Published: August 2020

Abstract
The effect of two drill fluids on the survival rate and linear growth rate of bivalve mollusks Mytilus edulis has been studied. The standard water-based drill fluid includes barite and carboxymethyl cellulose, which are highly toxic substances. The main components of an experimental presumably biodegradable solution are the ground brown algae Saccharina latissima, inhabiting the coast of the Barents Sea, and ferrochrome lignosulfonate, which also applies to toxic components. The minimal concentration of a standard drill fluid led to the 100% death after 9 days of exposure; the experimental drill fluid did not affect the mortality of mussels at all. The mollusks exposed to the concentration of 5 and 10 g/L of experimental drill fluid have been characterized by a high relative linear growth. An experimental drill fluid that does not contain barite and carboxymethyl cellulose may be considered safe for marine bivalves; and its components seems to be easily degradable, since some of them may be used as a food source by some detritus-feeding invertebrates
Technologies for processing fat waste and technical fish oils
Authors: Petrov B F , Volkova TP 
Published: August 2020

Abstract
Current economic and environmental conditions require a more rational approach to use of industrial waste. It is necessary not only to clean industrial effluents from pollution, but also to find rational ways of using pollutants extracted from the industrial effluents. This is especially relevant for fatty foam masses, which are formed during flotation treatment of the fat production runoff. The issue of their rational use has not been resolved yet. Traditionally, these products are buried at specialized landfills. Also, the question of using soap water flows, which are formed during refining the semi-finished fish oils with a solution of alkali, remains. Usually soap water flows are not used and are sent to the combined stock of fat production. An equally urgent problem of the fishing industry is the processing of semi-finished technical fish oils with a high acid number (over 20 mg KOH / g). Traditional cleaning of such semi-finished products is unprofitable. It requires a significant expenditure of material resources. In this case, the yield of purified fish oil is not more than 60 %. At the same time, the listed objects contain a significant amount of polyunsaturated fatty acids. Therefore, after additional processing, they should be considered as a secondary material resource for obtaining surface-active, film-forming, and anti-friction substances.

Authors: Poteshkina V A , Uskova I V 
Published: August 2020

Abstract
This paper is devoted to finding the scientific support for the development of commercial aquaculture. The article presents the results of examining the microbiocenosis of the commodity trout (Parasalmo mykiss) intestine. It was revealed that members of the genus Pseudomonas preveil in the microbiocenosis of the aquaculture intestinal contents. A small number of lactic acid bacteria, representing autochthonous microbiota and rare types of bacteria, such as coagulase-negative Staphylococcus spp. and Clostridium spp. being the components of fish allochthonous microbiota were discovered. Lactic acid bacteria were not found on the mucous membrane of the intestinal tract, due to the weak attachment of microorganisms in fish exposed to stress. The enzyme product was obtained from the bacteria with proteolytic activity in order to introduce this supplement as a feed probiotic into the artificial diets of cultivated fish. The advantage of the developed product is that the raw material (source) for its production are the bacteria isolated from rainbow trout intestine from experimental cage farms. The maximum activity of selected proteases was observed at bacterial concentration xio8 cells/ml. Proteolytic activity in the enzyme product from bacteria of the genus Pseudomonas spp. is higher than in the enzyme product obtained from the primary culture of E. coli.Antibiotic resistance of the selected isolates from Pseudomonas spp. Cefotaxime, which is recommended to use for prevention of bacterial infections when forming the broodstock was determined. Pseudomonas showed high sensitivity to a number of broad-spectrum antibiotics, such as ciprofloxacin, gentamicin. The obtained results of microbiological research can be used to develop the strategy of antibacterial therapy in fish farming.
Features of the composition and productivity of Tuloma river’s estuarine hydrofytocenoses
Authors: Priymak P , Priymak E 
Published: August 2020

Abstract
The species composition and productivity of communities of higher aquatic vegetation in the Tuloma River estuary, in the North-Western part of the Kola Peninsula, is studied. Samples with streamside vegetation were taken several times during the 2019 growing season from the littoral and sublittoral zones. Subsequent investigations revealed that macrophyte growth begins in April (offshoots of Ranunculus schmalhausenii), the mass germination period is estimated at the end of May to early June (representatives of the genera Potamogeton, Callitriche). The beginning of the growing season is influenced by ice conditions. The last vegetative plants are found in November (Potamogeton, Elatine, Batrachium). Analysis of the species composition of the samples revealed that the most environmentally plastic plants are water-starwort (r. Callitriche), pondweed (Potamogeton perfoliatus L) and water moss (Fontinalis sp.): occurring in the drained zone and on the sublittoral. The production of the studied phytocenoses reaches its peak in August (up to 110 g/m2 of absolutely dry mass), the main contribution to which is made by pondweeds. The distribution of accumulated phytomass over the horizons shows that the communities that are least susceptible to drainage are characterised by maximum productivity. These results may be important when monitoring hydrobiocenoses of the Tuloma river basin.
The influence of diesel fuel on morpho-functional state of Ulvaria obscura (Chlorophyta)

Published: August 2020

Abstract
There was researched the influence of diesel fuel (DF) on morpho-functional state of Ulvaria obscura (Chlorophyta) of the Barents sea. The reaction of algae on oil products depends on concentration and duration of toxicity. Under the concentration up to 5 mg/l (100 MAC - maximum allowable concentration) there were no visible changes in cell structure during 10 days of experiment; by its end the photosynthesis of algae decreased, probably due to growth of bacterial film on the surface of thalli, preventing photosynthetic apparatus from the light. On the 7th day the number of heterotrophic bacteria increased twice, staying on this level till the end of experiment, the number of hydrocarbon oxidizing bacteria also increased. Under 1000 MAC the chloroplasts lost green colouring, the intensity of photosynthesis significally decreased, but plants maintained vitality. On the 3rd day under 2000-3000 MAC the vacuolization of cells, the destruction of cell structures occured, parallel with the cessation of photosynthesis and the death of macrophytes. The activity of antioxidant system (AAS) in experiments with DF was high, appeared by increasing of formation of hydrogen peroxide and intensity of superoxide dismutase and catalase ferments synthesis. U. obscura adaptates to concentrations of DF up to 2000 MAC.
Modern concept of technological processes modal control in a state space combined with wavelet monitoring of current modes
Authors: Fedosenkov D B , Simikova A A , Fedosenkov B A 
Published: August 2020

Abstract
The article deals with the aspects of modal control in spaces of system states and wavelet time-frequency distributions. On the example of a mixture-producing aggregate mathematical models are formed to represent technological feeding material flow rate signals, and the relevant vector-matrix model based on the state space method is developed for the feeding devices unit (FDU). It is revealed that the signals generated by the feeders, are non-stationary in frequency and amplitude. They cannot be adequately interpreted by standard analysis techniques, e.g. such as the Fourier transform. To identify current operating modes of the feeding unit, it is proposed to use the apparatus of wavelet transforms, which allows you to identify local features of the flow signals in a combined time-frequency medium with essentially larger information richness and semantic clarity. For the aim of controlling current modes in FDU a closed automatic modal control system (CACS) with a full state vector feedback has been developed. In the modal control algorithm the feedback matrix is permanently recalculated in real time, which forms the specified localization of the poles constellation. Specified non-stationary feeding modes are demonstrated to represent the essence of modal controlling in the FDU.

Abstract
The article deals with the aspects of occurring the effect of structural and parametric non-stationary states of various kinds in the models of feeding devices (FD), the latter is considered as the part of a continuous-type mixture-producing aggregate. Relevant features of such an effect are revealed and discussed. In particular, different types of transient modes that occur in the feeding devices under increasing or decreasing the load applied to the intake part of feeders are introduced and described. To demonstrate the complexity of feeding devices models, the distribution of numbers and types of poles for models of different FD-unit configurations have been submitted here. Also we operate with concepts of the so-called autonomously sporadic and forced-modal transient processes, and their images in the forms of 1D-signals and time-frequency distributions are brought in. Finally, the procedures of calculating the modal controller parameters, i.e. the full state feedback matrix, are given in detail.
