Концепция устойчивого развития горнопромышленного региона Кабардино-Балкарии на основе использования хвостов обогащения Тырныаузской фабрики в закладке выработанного пространства

Introduction. Generalization of the world experience of integrated development of deposits indicates that the solution of the issues of involvement of mining and ore processing wastes in industrial exploitation is an urgent scientific and practical task. Therefore, the article presents the results of research on the possibility of using old tailings of ore dressing of Tyrnyauz tungsten-molybdenum combine (TTMK) to backfilling space in the process of finalization of reserves of Tyrnyauz deposit. Methodology and methods of research. The methods of research are the analysis of data on the formation of tailings of Tyrnyauz enrichment plant, laboratory experiments to study the material and granulometric composition of tailings, thermo-gravimetric analysis of tailings and study of strength properties of mixtures prepared based on tailings. Discussion of research results. The results of tests of samples of backfilling prepared based on initial and burnt samples of old tailings with the addition of different cement and water consumption are shown, which in the dynamics of strength gain testify to the possibility of obtaining the given characteristics of the filling massif in the required terms of its exposure at different thicknesses of ore bodies being finalized and the variants of development systems adopted in this connection. Conclusion. The possibility of preparation of stowing mixtures based on old tailings of Tyrnyauz enrichment plant has been proved. Resume. The choice of a specific composition of solidifying backfill mix will be made depending on the capacity of the deposits to be reworked and the variant of the deposit reserves reworking system determined by it with the use of floorchamber systems of development with two-stage order of reserves extraction in chambers of I and II stages. In addition, the rest of the accumulated reserves of technogenic raw materials in the tailings pond may, if necessary, serve as a resource for backfilling the mine workings at the second stage of development of the overlying reserves of the deposit. Proposals for practical application and direction of future research. The obtained results can be used in development of technological solutions aimed at increasing the efficiency of involvement of technogenic raw materials from tailings ponds and finalization of the main reserves of deposits when using the development systems with backfilling of mined-out space.

El algodón y su respuesta a diferentes condiciones hídricas del suelo

Introduction: One of the biggest problems in cotton farming in the Comarca Lagunera, Mexico, is the low efficiency of irrigation, since the large quantities of water used for this crop result in water shortages. Objectives: To determine the response function of the cotton crop to different soil moisture contents, as well as the water use efficiency. Methodology: Seven treatments were evaluated in the field: 40-40, 40-80, 60-60, 60-100, 80-40, 80-80 and 100-60 % of available moisture consumed (AMC) by the cotton plant at two phenological stages. Treatments were distributed in a randomized block design with four replications. Results: The highest cotton yield (8.7 Mg∙ha-1) was obtained with the treatment that developed under 63 and 62 % AMC at the first and second stages of development, respectively, by consuming 97 cm of water. Limitation of the study: The models do not predict satisfactorily when extrapolating outside the range of moisture levels considered in the study. Originality: No studies have been reported on extreme favorable and unfavorable conditions of soil moisture content in cotton to know its productive response. Conclusions: The obtained model maximizes cotton production (8.74 Mg∙ha-1) with a water deficit of 59 and 56 % AMC. The highest water productivity (0.945 kg∙m-3) was obtained with 81 and 82 % AMC and 78 cm of water consumption.

DEVELOPMENT OF THE ROMAN CATHOLIC CHURCH IN ODESA REGION (LATE XX – BEGINNING OF XXI CENTURY)

The purpose of the study is to highlight certain aspects of the development of the Roman Catholic Church (RCC) in Odesa region in the context of its problems and achievements at the end of the 20th – beginning of the 21st century. The scientific novelty of the work lies in the fact that, for the first time, a comprehensive study of the peculiarities of the development of the RCC in Odesa region against the background of historical events of the late 20th – early 21st centuries is proposed. On the basis of archival documents, the main stages of the activity of the RCC in Odesa region in the specified period are considered. It was found that the first stage on the way of the revival of the Church fell on the 1990s. Its characteristic features were the return of buildings previously confiscated by the Soviet authorities to Catholic communities, their reconstruction and restoration. During this period, it was possible to create a network of religious communities adapted to the conditions of activity in the plane of a multi-confessional environment. It is indicated that this process was under the control of the Department for Religious Affairs, which operated under the Odesa Regional State Administration during 1996-2005. It has been proven that the second stage of development of the RCC began at the beginning of the 21st century, which was due to the arrival of Pope John Paul II in Ukraine. The main achievements of this period are analyzed: the foundation of the new Odesa-Simferopol diocese headed by Bishop Bronislav Bernatsky, the increase in the number of believers, the activation of educational and charity work, activities aimed at improving inter-religious relations in the region. The intellectual and religious ties of the RCC with representatives of state structures and the public have been clarified. In the conditions of full-scale Russian aggression, the RCC took an active position in supporting the population of Ukraine and providing them with appropriate humanitarian aid. Further studies of church history include research on the construction of Christian churches in the south of Ukraine.

THE ANIMUS OF THE MAIN CHARACTER IN “GIRL MANS UP” NOVEL BY M-E GIRARD

This research is conducted to discover the animus of a masculine girl in the novel titled “Girl Mans Up” written by M-E Girard. This research applies an analytical psychology approach, specifically archetypal approach with the concept of animus archetype proposed by Carl Jung. Animus is the masculine qualities or traits in females’ psyche, in opposition with her outer appearance. This research focuses on the stages of the animus development of the main female character whose outer appearance was not feminine. The research method used is descriptive qualitative method. To collect and analyze the data, the researchers use library research method. There are two types of data, which are primary and secondary. Primary data are collected from the novel and secondary data are collected from books and articles related to animus to support the research. The analysis shows that the main character’s animus was on the first and second stage of development, with three data for Man of Power stage and six data for Man of Action stage, and that gender expression does not fully signify the person’s psychological traits.

Tradition of Beaded Decoration in the Ukrainian Folk Costume: Reconstruction of the Second Stage (Based on the Materials of Western Regions of Ukraine)

The article continues the previously started reconstruction of ethnic artistic tradition of beaded decoration in the Ukrainian folk costume. The authors’ vision of the second stage of development of this tradition (the end of the 19th– the middle of the 20th centuries) is presented. It was found that at the second stage of its development, the tradition of beaded decoration in the Ukrainian folk costume went through the phase of creative uplift. Ukrainian folk craftsmen considerably expanded the arsenal of technical as well as artistic and stylistic means of their creative works. The following techniques were used: typesetting, sewing “v prykrip“, stringing, weaving, embroidery, etc. The typology of beaded components of the folk costume expanded significantly. Alongside with overhead jewelry and headdresses, the beaded decoration emerged in the structure of several old and new components of clothes and accessories. By virtue of the implementation of the techniques of weaving and embroidery, artistic stylistics developed further. In the compositions of beaded components of the costume, apart from the motifs of geometric shapes, the motifs of geometrised shapes appeared, as well as the national symbols. The colouring of beaded artworks was significantly enriched. Successful development of all-Ukrainian and local features of folk art continued. The knowledge, accumulated by the authors, will be of a great interest to ethnologists, art historians as well as modern folk craftsmen of beaded artworks.

Histological features of the bladder wall in yorkshire piglets in the age aspect

Yorkshire pigs occupy one of the first places in livestock farms in different parts of the world. This is due to the fact that breeding boars of this breed are widely used by farmers and owners not only of large livestock complexes, but also by private farms for crossing with other breeds of adapted pigs to increase the meat indicators of offspring. Pigs of this breed are very sensitive to sudden changes in ambient temperature, often suffer from overheating or hypothermia, which can affect the health of internal organs and body systems and can lead to diseases of the urinary system in general and in particular the bladder. The purpose of our study is to study the features of the histological structure of the bladder wall in Yorkshire piglets in the age aspect. Cadaver material for the study was delivered to the Department of Animal Anatomy of the Federal State Budgetary Educational Institution of the Russian Academy of Sciences from the Idavang Agro pig breeding complex in Nurma village, Tosnensky district of the Leningrad Region. The study was conducted in three age groups, according to the periodization of pig life: the first stage of development – newborn piglets (1-4 days of the postnatal period); the second stage of development – the first dairy (5-21 days of the postnatal period); the third stage of development – the second dairy (22-45 days of the postnatal period). From the first stage of development, newborn one-day-old piglets were used; from the second stage – animals 10-14 days; from the third – piglets 28-30 days of the postnatal period of ontogenesis. The average body weight of piglets of group 1 is 550 g.; Group 2 is 1800 g.; Group 3 is 3000 g. In total, five piglets were inherited in each age group. The age was determined by the bonus cards and from the words of the chief veterinarian of the farm. To achieve this task, a set of traditional morphological research methods was used: fine anatomical dissection, histological, photographing and morphometry. Histological examination revealed that in Yorkshire piglets, the bladder wall has a typical histological structure and consists of mucous, muscular, and serous membranes. Morphometric indicators of histological structures of the bladder wall were determined and it was concluded that these values of thickness and diameter in males slightly exceed those in females.

Conceptual issues and stages of establishment of military chaplainty in independent Ukraine

The formation of the chaplaincy movement in the context of the formation of independent Ukraine (after 1991) required the solution of a number of issues, primarily of a conceptual nature. The initiators of the restoration of chaplaincy faced the underestimation of the chaplaincy factor, the risks of transferring interfaith disputes to the military environment. In fact, it was a question of finding their own model of chaplaincy service, which would provide an optimal model for organizing the work of chaplains. The authors propose to divide the development of the chaplaincy movement in independent Ukraine into three stages, which differ not only chronologically but also in their characteristics. The first stage (1991-2005) was characterized by a rethinking of the role and place of religion in the activities of the Armed Forces of Ukraine. The idea of a chaplaincy service was revived primarily on the basis of the volunteer movement. Volunteers also encouraged churches to form appropriate structures that would be responsible for chaplaincy work. At this stage, the driving force behind the formation of the chaplaincy movement was the unstable informal ties between church and security forces in Ukraine. With the advent of the first legal acts that regulated the search for optimal models for creating the chaplaincy institute, the second stage of development of the chaplaincy movement in Ukraine began. It lasted from 2006 to 2013. During this time, regulations were developed and implemented that institutionalized the relationship between the Ministry of Defense of Ukraine and the country's largest churches and religious organizations. The third stage began with the beginning of the Russian Federation's attack on Ukraine in 2014 and continues to this day. The annexation of Crimea and the outbreak of hostilities in eastern Ukraine created the need to sharply increase the number of chaplains and to legalize them in military institutions. Already in 2015-2016, the formation of the state regulatory framework of the chaplaincy institute began and staff positions of chaplains in military units were introduced. On the other hand, there has also been a qualitative growth in the theoretical and practical training of chaplains and their material support. These processes show that the establishment of the institute of military chaplaincy in Ukraine has actually taken place. In each period, the authors highlight the problematic issues that government agencies and religious organizations addressed in organizing the chaplaincy movement. Particular attention was paid to the attempts of activists to form their own model of chaplaincy ministry and the problematic issues of improving the quality of chaplains' training. In particular, it was pointed out that the best way for Ukraine is to organize separate chaplaincy faculties in the country's higher educational institutions to train specialists at the level of world standards.

Determination of key drivers of digital transformation of company by the example of assessment of digital maturity level of educational establishment education

The present paper examines the main components and development stages of digital transformation of a company and analyses the factors impeding it. One of such factors is the inflexibility of internal culture, particularly insufficient digital culture of a company. The paper gives data obtained through the empirical study on the initial stage of digital transformation. The survey of people working in a Moscow higher education institute was carried out about their opinion on the level of current digitalization of their university. As part of the survey 150 people were polled. The results show that top managers of the university are exceedingly optimistic and overrate the level of digital maturity of their organization. The university is now on the second stage of development

HYPOTHETICAL RECONSTRUCTION OF THE PLANNING STRUCTURE AND ARCHITECTURE OF THE HIGH DEFENSIVE WALL OF THE MIDTOWN OF LVIV FOR THE 13th-14th CENTURY

Lviv is one of the cities in Ukraine that had a highly developed system of medieval fortifications. This system of fortifications was built in the XIII-XIV centuries, modernized many times and served until the 18th century. However, today in Lviv, only small remains of the medieval fortifications of the city center have been preserved in the form of architectural objects - several fragments of the defensive wall and only one defensive tower, which was rebuilt into a tower in the 16th century. These preserved objects belong to the so-called High defensive wall. These are: a fragment of the lower part of the defensive wall on 16 Svobody Avenue, a fragment of the wall and the Povoroznyk tower (connected to the building of the City Arsenal), a fragment of the wall on the Pidvalna Street (to the Royal Arsenal is attached), a fragment of the wall and the remains of the corner Rymarska tower, the remains of the foundations of the corner Shevska tower, a preserved and superimposed fragment of the wall near the Vienna coffee house (12 Svobody avenue), the remains of the wall in the basements of the building on 9 Mickiewicz Square. The rest of the remains of the High Wall are underground in the state of archaeological objects. These unique objects of military construction are not registered as architectural monuments. Also, they are not listed as monuments of archeology. Every fragment of city defense fortifications preserved today is, as a rule, a valuable document of its era and requires careful protection and preservation. Therefore, the study of the architecture of the medieval defense complex of the Lviv city center, which was created before the appearance of firearms, is important both for the history of the city and for the history and theory of domestic military architecture. This paper presents an analysis of the first stage of the construction of the High Defense Wall around the Lviv midtown and presents a hypothesis regarding its architectural solution. Special attention is paid to the issue of the planning structure of the fortified belt. The hypothesis that initially the defensive contour of the High Wall had a rounded shape has been substantiated. The argumentation about the towerless nature of the defensive belt at the first stage of the development of its fortifications is presented. There were two gates at the first stage of the construction of fortifications, which were called Tatarska and Halytska. The architectural solution of the gates was specific. The gate was formed by two towers (semicircular in plan). The gate-entrance with drawbridge was located between two high towers. At the second stage of development, the defensive High Wall was modernized, raised and a number of defensive towers were built. At the third stage, the planning scheme of the fortified belt changes. The line of the High Wall in the eastern span acquires a rectangular character with outward-projecting towers and corner towers.

Cryptorchidism: The dog as a study model.

Cryptorchidism (CO) or undescended testicle is an abnormality of male gonadal development that can generate long-term repercussions in men, such as infertility and germ cell neoplasia in situ (GCNIS). The origin of these alterations in humans is not completely clear, due to the absence of an animal model with similar testicular development as in humans with CO. This work intends to describe the testicular histological development of dogs with congenital CO, and determine whether the species could adequately serve as a study model for this pathology in humans. The study was carried out with 36 dogs, equally distributed in two groups: healthy control (CTRL) and CO groups. The contralateral testis to the undescended one in CO group of the animals was considered and analyzed. Each group was subdivided in three stages of development: (1) peripubertal stage (6–8 months), (2) young adult (9–48 months) and (3) senile (49–130 months). Histological development, the presence of cells with gonocyte morphology, cell proliferation, testicular lipoperoxidation and hormonal concentrations of testosterone, estradiol, FSH and LH were evaluated and described. In the cryptorchid testes, the first histological alterations appeared from the first stage of development and were maintained until the senile stage. A pronounced testicular lipoperoxidation occurred only in the second stage of development. The histological alterations due to CO were markedly evident in the young adult stage. Testosterone concentrations witnessed a decrease starting from in the second stage and kept on until the last stage. The contralateral testes of the CO animals showed alterations that positioned them between the control and CO testes. Testicular development of dogs with CO is similar to that of humans. The results of the study suggest that this species could serve as a suitable model for the study of CO in humans.

Green Human Resource Management: A Bibliometric Analysis

Despite the growing attention which green human resource management (GHRM) has been gaining, the field is still remarkably young, and conceptual clarity is yet to be attained. A bibliometric review of GHRM from 2010 to 2020 was conducted on the Web of Science and analyzed using the VOSviewer software package, version 1.6.16 developed by Van Eck and Waltman (Leiden, The Netherlands). The results show the exponential growth of this topic, although there seems to be no consensus regarding its definition, conceptualization and measurement. Concerning its conceptual development, GHRM seems to currently fit the second stage of development (evaluation and augmentation) of Reichers and Schneider’s three-stage model of the evolution of constructs. Future research seems to point in the direction of establishing the barriers separating GHRM from other human resource management topics, defining green practices and determining the antecedents and consequences of GHRM.

DIGITAL TECHNOLOGIES IN AGRICULTURAL ENTERPRISE MANAGEMENT

Abstract. The article investigates the theoretical and practical principles of using digital technologies in the management of agricultural enterprises. The dynamics of Ukraine’s position in the world ranking of digital competitiveness is analyzed, the leading countries in digital transformation of economic systems are identified in order to study the progressive experience of digitalization of the economy, its spheres, agriculture in particular. The evolution of technologies and business ideas in agriculture, which can be represented as a two — factor model of development, is studied. The comparative analysis of approaches to conducting agrarian business is carried out. It is noted that almost all large holdings in Ukraine are now actively investing and implementing digital solutions, it can also be seen that at all levels of agricultural production the country already has its leaders with extensive experience in implementing digital technologies. It is hypothesized that an important indicator of the development of digitalization are digital technologies formed with world experience. They can be divided into eight main areas of activity: FMS (farm management systems); data collection and aggregation (for precision farming), forecasting; marketplaces; robotic equipment and drones; sensors; reasonable irrigation; animal husbandry; next generation farms. Based on world experience, the peculiarities of the application of certain digital technologies in certain areas of agriculture are considered and assumptions are made about the possibility of their use in the realities of domestic agricultural production. It is concluded that the path or vector of digitalization in agriculture can be represented as three stages for agricultural holdings and two stages (without the last) for relatively small farmers: the first stage characterizes the agricultural company with efficient business processes (here must be implemented and fully integrated internal accounting systems). and a single digital back office); the second stage of development is a digital technology company (it uses innovative technologies such as precision farming, artificial intelligence (AI), computer vision (CV), machine learning (ML), etc.); the third stage is the ecosystem of the agricultural holding (a whole infrastructure of innovations has already been built here). Keywords: digitalization, digital technologies, agriculture, digitalization of agricultural production, digital infrastructure of agricultural enterprise.

Сравнительный анализ кольцевых хронологий современной и археологической древесины Тоболо-Ишимского междуречья и перспективы построения региональных дендроархеологических шкал

The article examines a collection of eight ironcollared hooksfrom early medieval burials of archers in the Kuznetsk basin. Theseitems were found on four funerary sites Sapogovo, Shestaki-II, Esaulka and Vaganovo, dated by researchers at different intervals within the 7th –10th centuries. The finds are subject to typological classification, typological-chronological and comparative analysis, as well as ethnocultural characterization. As a result of the classification, five types of products are identified. All of them belong to the archaeological and ethnographic complex of those buried according to the rite of cremation on the side and the Saratov archaeological culture at the first and second stages of development in the Kuznetsk basin. It was established that in the early Middle Ages, warriors only in special cases used iron bell hooks. A wide typological range of these products, refl ecting their design features, indicates the lack of stable traditions for their manufacture in the region, which allows us to conclude that they are borrowed from neighboring territories of Sayano-Altai. This is also evidenced by a comparative analysis that allows us to conclude that the use of iron hooks for fastening the quiver in the Kuznetsk basin reflects the general dynamics of the development of similar products in Central Asia and steppe Eurasia during the Middle Ages.

Колчаны у средневекового населения Кузнецкой котловины

The work is devoted to the study of weapons of the medieval population of the Kuznetsk basin. Cases of the discovery of quivers in medieval funeral complexes on the territory of the Kuznetsk basin are described and summarized. This category of items is poorly researched, which is due to the poor safety of these items and, as a result, a small source base. According to the material of manufacture and the shape of the quivers, the primary classification of finds is carried out, whose design has been preserved almost completely or can be reconstructed. Two groups and three types of birch bark quivers are distinguished. According to the dating of the monuments on which the quivers were found, the periods of existence of each type on the territory of the Kuznetsk basin are hypothetically determined. Conical quivers with a pocket existed at the end of the 1st millennium and the developed Middle Ages. Conical and cylindrical quivers with a horizontal top were used in the developed Middle Ages. A wide range of analogies from monuments of the early and developed Middle Ages from neighboring and remote territories of Central Asia are given to the selected types of quivers. A similar dynamics of the development of similar types of quivers in other territories is recorded. The studied quivers are part of the subject complex of the second stage of development of the Saratov (second half of the VIII-X centuries) and Shanda archaeological culture (XI-XIV centuries).

New approaches to the organization of district heating

District heating systems in Ukraine's cities are in deep crisis and need decisive action to overcome it. The crisis began long ago, in the 1990s, and is gradually deepening. Several attempts to stop this process and level the playing field at the state level have failed. At the same time, the process of intensive development of such systems has begun in the countries of Northern Europe. Moreover, both at the theoretical level and in the practical implementation of theoretical developments. According to the theoretical analysis of the life cycle of district heating systems, they are now in the fourth stage of their development in the countries of Northern Europe. This stage has the main features - low temperatures in the network (temperature graph), the combination of district heating systems with district heating systems and their deep integration into the overall energy system of cities, as well as the gradual replacement of fossil fuels with renewable energy sources. District heating systems in the cities of Ukraine are only in the second stage of development. In order to remain competitive against decentralized systems, a sharp transition to the third and at least partially the fourth stage of development of such systems is required. district heating systems are in the active phase of their expansion in European countries and have great prospects for further development, including in Ukraine. District heating systems together with cold supply systems in the process of development are integrated into the energy supply systems of cities and in general in the urban economy. Renewable heat sources will increasingly displace the equipment for combustion of excavated fuel with the prospect of complete abandonment of the latter. In order to preserve the remnants of district heating systems in Ukrainian cities, it is necessary to study and use the experience of the Nordic countries and organize this work at the state level. Unfortunately, neither the governing bodies nor the general public have this understanding. The extraordinary task is to improve the skills of managers and the operational status of city district heating systems and officials of city administrations.

NEW EXHIBITS OF ITEMS WITH CHAMPLEVE ENAMELS IN SUMY REGIONAL MUSEUM (PRELIMINARY REPORT)

During 2018—2020 items with Champleve enamels were presented to Sumy Regional Museum by Sumy residents, S. I. Gutsan and R. A. Bobkov. They were shown at an exhibition dedicated to the 100th anniversary of the Museum in September 2020. The collection consists of more than 70 items (tabl. 1). There are brooches (horseshoe-shaped, triangular, round), pendants (cruciform, lunnula), chains, bracelets, diadems, torques, appliquй, finger-rings, trapezoidal pendants, spurs etc. Because these finds were kept in private collections and were presented to the Museum by their owners, the items could be considered accidental finds except location of them was more or less accurate.
 Preliminary analysis of things from the collection allowed us to determine the following. The area of finds includes different areas of Sumy region, but those found in Sumy’s suburbs significantly dominate, and by dating they mostly belong to the second stage of development of East European Champleve enamels, according to E. Gorokhovskyi — to the middle and second half of 3rd century. Metal and enamel of things were analyzed by the researchers of The Institute of Applied Physics of NASU using an X-ray fluorescence spectrometer.
 Situation around archeological monuments requires a rapid reconstruction, adaptation of science to new unfavorable conditions. This publication is prompted by an attempt to obtain maximum information from sources whose reliability is questionable. Moreover, the things analyzed in this publication are of great importance for solving many important questions of archeology, in particular, for the reconstruction of the Slavonic peoples’s genesis.

The second stage of development of artificial reproduction technology of northern pike in the Kaliningrad lagoon basin

The second stage of development of northern pike artificial reproduction technology for stocking with larvae and fry in the Kaliningrad lagoon basin is considered in this paper. Today northern pike natural stocks in the Kaliningrad lagoon basin are not numerous due to unregulated fishery and limited spawning habitat. Since the 1990s, in many countries of the world, the number of natural stocking northern pike has gradually decreased and at present does not exceed several thousand tons. This problem is also relevant for the Baltic Sea basin, where the modern catches of northern pike in the Curonian and Kaliningrad lagoons make 7,2 and 0,6 tons respectively. At the present time different scientific programs and actions are realized in many countries to restore natural stocks of northern pike. One of the most promising solutions of low northern pike numbers problem is organization of northern pike artificial reproduction in the territory of the Kaliningrad Region. Based on our earlier research in the Curonian lagoon basin, the second stage of development of the technology of northern pike artificial reproduction was carried out on the basis of the educational and experimental farm of KSTU in 2020. Prespawning maintenance of 25 northern pike producers with the use of cages from deli, ponds and reclamation canal was carried out, as well as egg incubation and holding of prelarvae in RAS. As a result of the conducted researches, it was established, that the reproductive products of northern pike producers have high quality and the prelarvae at the stage of incubation have high survival rate (82,2–91,7%). The calculated of biometric parameters of producers and their reproductive products, confirmed the correlation between the weight of females and their fecundity, which was 0,86 and 0,95. The scheme of keeping of producers and incubation of northern pike eggs tested at the second stage has shown the prospect of providing 50% of the need in stocking of young northern pike in the Kaliningrad lagoon with the use of 100% stock of producers.
