Authors: Zakonnova Ludmila Ivanovna , Nikishkin Igor Vasilievich
Published: April 2021

In the process of work on the reproduction of the channel catfish Ictalurus punctatus (Raf.) In the conditions of LLC «Belovsky Fish Industry», the main problem was the timely production of high-quality offspring, associated with differences in preparation for spawning of females and males. In this regard, the purpose of the work: to develop and test various options for carrying out spawning campaigns, including those using various drugs for hormonal stimulation of manufacturers. The results of testing Nerestin preparations in 2006–2008 are presented. In 2006, the drug Nerestin-5x (N5x) was tested. The main problem was identified: 80% of the injected females matured, but the passive males did not start fertilization. It was proposed to adjust the total dose of H5x for females towards a decrease, depending on the degree of their initial readiness, and for males — towards an increase. In 2007, drugs H5x and H7A were tested. A change in the injection scheme of males in 2007 compared to 2006 (an increase in the total dose to the norm of females, but with the use of the drug H5x, and not H6A or H7A during the first two injections) increased the readiness of males for spawning slightly. In 2008, males were brought into the hatchery one month earlier than females, increasing the maturation period of males and changing the temperature rise schedule to prepare for spawning. The drug H7A was used. Despite the increase in the total dose of H7A for males to the total dose for females, their readiness for spawning was still insufficient. To a greater extent, the readiness of males was influenced by an increase in the period of keeping and feeding. The conclusion is drawn that preparations H7 and H7A are quite applicable for artificial reproduction of channel catfish, but the technique of application must be improved by adjusting the conditions of pre-spawning maintenance of producers and the injection scheme.

Authors: Trenkler Igor Vladimirovich
Published: April 2021

The history and contemporary state of global aquaculture of sturgeons and paddlefish are reviewed. 5th part is devoted to sturgeon breeding in the basin of Black sea (without countries of former USSR reviewed earlier) аnd in the Middle East. Six species of sturgeon once migrated in the Danube River and Turkish rivers Yeşilırmak, Kızılirmak and Sakarya for spawning: anadromous beluga Huso huso, Russian sturgeon Acipenser gueldenstaedtii, stellate sturgeon A.stellatus, European sturgeon A. sturio and the river resident ship sturgeon A. nudiventris and sterlet A. ruthenus. Sturgeons had played an important role in the history Black sea fisheries, but due to overexploitation, followed by extensive river regulations and deterioration of water quality decrease in their populations has led most of them to the verge of extinction. During the 20th Century, world demand for sturgeon meat and caviar has inflated the economic value of sturgeons so Danube basin countries and Turkey develop commercial aquaculture and conservational programs. As result of protective measures the limited natural spawning of beluga, Russian and stellate sturgeons and sterlet is preserved in Danube. In Sakarya River last spawning population of stellate sturgeon exists. These species and Siberian sturgeon are important objects of commercial aquaculture in all countries of Black sea basin. The leaders of commercial sturgeon farming in this region are Bulgaria and Israel. The sturgeon aquaculture of Hungary and Turkey developed rapidly. Saudi Arabia and United Arab Emirates are important importers of caviar. Saudi Arabia is large consumer of caviar and UAE is one of main re-exporter of caviar. Both Arab countries develop own sturgeon aquaculture.

In the paper, preliminary results of hydrochemical, hydrobiological, parasitological and ichthyological investigations have been given, carried out on waters of the Lake Senezh in 2020 and compared with analogous works for 2004–2006. The ecosystem of the given water object is extremely understudied. In the size structure of fish species, caught in 2020, dynamics of a good reproduction potential could be noted. The condition factor of all fish species is very high. One can see a significant prevalence of females over males, excepting bream, in all fish groups studied. The water object investigated showed the 2,8 times MPC increase for iron in fish farming water bodies. Concentration of toxic elements in water samples and bottom sediments did not increase MPC for all other indices. The bacteriological water analysis showed insignificant increase of bacterial contamination at the area of the investigation station 6 only, what is most likely of the anthropogenic nature and is being a result of the littoral lake zone pollution. Parasitological analysis of the Senezh lake fishes indicates of o high level of their invasion. 11 parasites species were found in 3 fish species investigated, which were represented by 73% of trematodes at the metacercaria and maritas stage. The fish ergasiles problem, existed in this water body since 2005 and up to-date, continues. In zanders gills, parasitic Ergasilus sieboldin were found. The given work would be interesting for investigators who will study the Senezh lake as well as other water bodies of the Moscow area.

Authors: Silkina N. I. , Mikryakov D. V. , Mikryakov V. R.
Published: April 2021

A study of changes in some immunological parameters of fish blood serum depending on the average monthly air temperature was carried out. The studies were carried out on bream aged 3+, with an average weight of 375 ± 30 g and a length of 290 ± 20 cm, caught in the Volga reach of the Rybinsk reservoir. The fish were caught using fixed nets in February for several years and the average monthly air temperature was recorded. The studied fish were sampled from the tail vein. Blood was collected in a dry sterile test tube and kept at room temperature. After blood coagulation and retraction of the clot, the serum was taken with a syringe with a fine needle and transferred to another tube. To assess the state of natural immunity in the blood serum, the level of bactericidal activity and nonspecific immune complexes was analyzed. Based on the data obtained, the number of immunodeficient individuals was determined. Variations of the studied parameters in years different in average monthly air temperature were established. The greatest differences between the indicators were revealed in the years with the highest (2003) and lowest (2006) mean monthly temperatures. The minimum indicators of bactericidal activity were recorded in 2003, and the maximum — in 2006. The highest content of immune complexes and immunodeficient individuals was established in 2003, and the lowest in 2006. The study showed the relationship between an increase in the average monthly air temperature and a decrease in functional activity nonspecific humoral immunity. Based on the data obtained, it was concluded that the temperature factor influences the mechanisms of innate immunity of fish.
The aquaculture of Acipenseriformes. Part 6. Northern and South America
Authors: Trenkler I. V.
Published: April 2021

The history and contemporary state of global aquaculture of sturgeons and paddlefish are reviewed. The paddlefish Polyodon spathula became first object of cultivation of Acipenseriformes in USA. The paddlefish has high rate of growth in ponds using natural feeds, mature females can produce about 15% of their body weight in roe similar to eggs of star sturgeon Acipenser stellatus. Some liabilities include juveniles vulnerable to bird predation, poor tolerance to high densities, low oxygen and handling stress, waiting period of at least 7 years before females produce eggs. The paddlefish farming is carried out mainly in Kentucky, Indiana, Missouri and Alabama in polyculture with canal catfish Ictalurus punctatus or freshwater shrimp Macrobrachium rosenbergii. The most important object of North-American sturgeon breeding is white sturgeon Acipenser transmontanus, the biggest and fast-growing species of Acipenser genera. The largest commercial sturgeon farms are located in California, Idaho and Florida. A research program on biotechnology of white sturgeon farming has been initiated by the University of California at Davis in December 1979. The first successful artificial propagation of white sturgeon from Sacramento River was carried out in 1980, the first hatchery females matured in 1994. The hatchery progeny of Snake River white sturgeon was received in 1988, the first females matured in 2000. The first caviar was processed only after maturation of second generation. In Florida and North Carolina farmers used for cultivation small number of Russian sturgeon A. gueldenstaedti, Siberian sturgeon A. baeri, sterlet A. ruthenus, beluga Huso huso and star sturgeon A. stellatus. The total annual volume of sturgeon farming in USA was equal to 1285 tons (1166 MT). In Canada the only object of sturgeon farming is white sturgeon with annual production near 2 tons of caviar. In South America Uruguay has developed sturgeon culture with one large farm created in 1994 using help of Russian specialists.

Fisheries research was carried out on the Khantayskoye reservoir in 1977–2020. This article presents the results of these works. In the first years after the flooding of the Khantayskoye reservoir, pike and common species of whitefishes (Siberian vendace, peled and whitefishpyzhyan) constituted the basis of the fishery. The share of other fish (carp, burbot, perch) was insignificant. The sharp increase in the food supply for planktophages and benthophages was short-term. Trophic depression began to appear in the early 80s (3–5 years from the moment the reservoir was filled). From this moment to the present time, whitefish species have a slowdown in linear and weight growth, an increase in the timing of puberty, a decrease in fertility. Of the whitefish fish, only Siberian vendace and whitefish are present in the fishery, the numbers of which have significantly decreased. Since the mid-2000s, the number of peled has decreased significantly and this species of fish has become rare in the reservoir. . Currently, there is a relatively high number of pike. Roach, ide, pike and perch actively mastered the channel of Kontiki, where before was practically absent. The increased number of these species affects the number of whitefish in their spawning areas, and their reproduction, including the safety of eggs.The parasite fauna of the main commercial fish species of the Khantayskoye reservoir was investigated. The most pathogenic were myxosporidia Henneguya zschokkei (Gurley, 1894), the causative agent of peptic ulcer disease in whitefishes.

In the agro-industrial complex of Russia, the share of the main types of agricultural machinery with a service life of more than 10 years is: for tractors — 61 %, grain harvesters — 47, forage harvesters — 42 %. Due to the extremely low provision of the Russian agro-industrial complex with modern tractors, the energy supply per 100 hectares of sown area is 150 hp. with technologically required 300–350 hp. On cattle farms, the level of complex mechanization of technological processes has decreased by 23 . Within the standard period, no more than 20–25 % of technological equipment is used and only 5–8 % meet modern requirements. The problem of updating the park of domestic agricultural machinery and livestock equipment can be considered only in a single complex with the disposal of these machines and equipment.

Authors: Hamed Farhan Yasin , Anokhina Adelia Zakirovna , Sudakova Natalia Viktorovna , Magzanova Damelya Kazhigalievna
Published: April 2021

It is shown that the leading role in the aquaculture of Iraq belongs to Cyprinids, which account for over 80 % of all fish farming production. The most widespread in the country are four main world species of carp aquaculture: common carp (Cyprinus carpio), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis). Basically, the traditional technology of growing Cyprinids in ponds is used, which includes the main fish farming processes: care of broodstock to prepare them for spawning, collecting eggs and milt, eggs fertilization and incubation of embryos, raising juveniles and marketable fish. Currently, there are about 2 thousand private fish farms, which have ponds of various sizes from 4 to 100 hectares. Cultivation of Cyprinids in Iraq is carried out mainly by extensive methods: the use of the natural food base of reservoirs with low fish stocking density in polyculture. The fish productivity of ponds varies greatly in different fish farms from 1,5 to 6 t/ha, which is due to economic reasons. The data on changes in the temperature of pond water during the year and hydrochemical indicators are given, which shows favorable conditions for Cyprinids rearing. Information on the use of compound feeds for growing carp in ponds is provided, and data on the composition and nutritional value of the feed used. The fish culture indicators for the main biotechnical processes of the rearing of four Cyprinid species in Iraq are described in detail. In the conclusion, it is indicated that for the effective development of aquaculture in Iraq, government support is needed in the form of a developed long-term program and legislative acts.

Published: April 2021

This paper presents the current state of research on the intestinal microbiota of fish of different ecological groups from water bodies of West and East Siberia. The present study focused on the gut bacterial diversity of 16 species/forms of fish (due to intricate taxonomical position of whitefish from Teletskoye Lake) inhabiting Chany Lake (Novosibirsk oblast), Teletskoye Lake (Altai Republic), Baikal Lake and other water bodies of East Siberia using molecular genetic methods. The analysis of the conducted studies shows the main features of gut bacterial communities in the digestive tract of fish and to better understand the features of the functioning of aquatic ecosystems in Siberia. In all studied fish (except for Lena grayling and Baikal omul), regardless of their habitat, taxonomy, digestive system structure (presence or absence of stomach and pyloric caeca) and feeding habits, bacteria of all four phyla (Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria) were found among the dominants. Such differences can also be explained by sample preparation techniques before sequencing that researchers may apply. Also, the uncultivated microbiota such as Pseudoalteromonadaceae (Lake Chany), Comamonadaceae and Bacillaceae (whitefish from Lake Teletskoye) and Rhodobacteraceae (Baikal omul and whitefish) were often found among the dominant bacterial taxa in the digestive tract of the most studied fish. Moreover, the data focused on the structure of gut bacterial community of fish will be useful for the development of aquaculture industry in the region, since the information makes it possible to identify pathogenic, opportunistic, and probiotic bacteria in aquatic ecosystems.

The Sniffing Kidney: Roles for Renal Olfactory Receptors in Health and Disease
Authors: Shepard Blythe D.
Published: April 2021

Olfactory receptors (ORs) represent the largest gene family in the human genome. Despite their name, functions exist for these receptors outside of the nose. Among the tissues known to take advantage of OR signaling is the kidney. From mouse to man, the list of renal ORs continues to expand, and they have now been linked to a variety of processes involved in the maintenance of renal homeostasis, including the modulation of blood pressure, response to acidemia, and the development of diabetes. In this review, we highlight the recent progress made on the growing appreciation for renal ORs in physiology and pathophysiology.
«...Out of the earned money from a sincere heart, I donate to orphans»: charitable assistance to Ukrainian prisoners of war from camp Rastatt and pows' charitable activities (1915-1918)
Authors:   Borys Grinchenko Kyiv University, Sribnyak Ihor
Published: April 2021

The article deals with the peculiarities of providing charitable assistance to captive Ukrainians from the Rastatt camp (Germany), as well as the specifics of the charitable activities of the camps. The prisoners Ukrainians have often acted as donors, raising funds for different national needs, for patients in the camp infirmary and so on. However, the prisoners did not refuse assistance to the Germans themselves – donating money to the German orphans of war and to the needs of the German Red Cross. Numerous donations have been made to build a monument that forever etched in stone the memory of the deceased Ukrainians. The prisoners, in turn, received charitable assistance from international and national Red Cross organizations, which had never been of a regular nature. Considering the scarcity of the camp rations and the quality of the food, the quality of the food is not always sufficient; the prisoners had some hopes of receiving charitable help. She was especially needed by patients from the camp hospital as well as prisoners with disabilities. The distribution of charitable assistance in Rastatt was carried out by the Central Committee, which was composed of elected representatives of prisoners.

Published: April 2021

In the article on the basis of archival documents the main directions of charity work in Volyn province during the First World War are analyzed. It has been found that they have played a leading role in organizing and assisting wounded and sick soldiers. To this end, hospitals were opened and maintained at the expense of local governments, educational institutions of various types and philanthropists. It is determined that the imperial authorities have strongly encouraged the population of the region to do this activity, including students and teachers of educational institutions. Particular attention is given to the organization of shelters for homeless children, whose numbers began to increase rapidly after the evacuation and forced eviction of civilians as a result of the Russian army's retreat in the summer of 1915, and the role of the Orthodox clergy in this was analyzed. Using the documents of the study period, it was proved that the imperial authorities encouraged the people of Volyn to do charity for the benefit of the military, as evidenced by a number of circulars. However, as a result of hostilities in the province and the policies of the Russian military command, the majority of the population became impoverished and unable to do charity work. This situation indicates serious miscalculations by the imperial authorities and the military. But despite the shortcomings and shortcomings, charitable activities have played an important role in helping the various sections of the population most affected by hostilities in the country.

Relations with the neighboring states in the framework of implementation of the european policy of the Republic of Belarus (90s years of the XX – XXI centuries)
Authors:   Mariupol State University, Bulyk Maksym
Published: April 2021

Foreign policy of the Republic of Belarus during the 90s. ХХ - the 21st century was distinguished by a certain dualism related to the officially declared by President A. Lukashenko desire for deep integration with the Russian Federation and interest in close economic cooperation with European states. At the same time, despite permanent political scandals, since the 2000s, the Belarusian authorities have regarded the EU as counterbalancing to strengthening the expansionist aspirations of the Russian ruling regime, led by V. Putin. Thus, the current study is substantiated by the cross-border issue of the EU status of the Republic of Belarus, the current geopolitical process taking place in Eastern Europe, as well as close histories, cultural and economic links, which require detailed consideration. An analysis of Belarus's relations with the European Union's neighboring countries allows us to draw several conclusions. First of all, the political relations of these states are developing at several levels. At the same time, problematic issues, whose roots lie in the consequences of the historical and political processes of the past remain relevant. In addition, the desire of Belarus's neighbors to be guided not only by the EU's strategy for this country, but also by seeking their own ways of influencing on official Minsk in the interests of compatriots or economic benefits, should be emphasized. In conditions where the Belarusian leadership is interested in establishing relations with Western countries, such plans are in the interests of Europe as a whole. At the same time, economic cooperation comes to the fore, in which Belarus plays the role of a powerful partner, able to meet the needs of European countries in the production of oil and wood processing, processing industry, etc. However, in the context of destabilization of the international situation related with the actions of the Russian Federation in Central and Eastern Europe, Belarus' vulnerability becomes one of the main risks for future relations with neighboring countries.

Attribute salience (Public Diplomacy) (see also issue attributes)
Authors: Marschlich Sarah
Published: April 2021

The variable “attribute salience” is described as the characteristics of a given issue that is portrayed in media coverage or other communication channels. It is generally measured in addition to issue salience and issue valence in order to analyze media portrayals of events, actors, or public discourses. Attribute salience is often measured in order to explore how particular issues are presented (instead of which in general), thereby contributing to second-level agenda-setting effects (McCombs et al., 1997).
 
Field of application/theoretical foundation:
Attribute salience is analyzed across different subfields of communication and media research, including the field of public diplomacy. In public diplomacy research, scholars measure attribute salience in the context of political communication or the representation of countries in the news media as well as on social media. Researchers embed the concept of attribute salience or issue attributes mainly in agenda-setting theory (McCombs & Shaw, 1972), analyzing it as an independent variable to derive with implications of news media coverage on audiences’ evaluations of certain issues.
 
References/combination with other methods of data collection:
When it comes to analyses on attribute salience in the context of issues and its link to public perceptions, a mixed-method study design incorporating content analysis in combination with surveys is used to validate attribute salience.

Authors: İYİGÜN Necla Öykü
Published: April 2021

Research shows that family owned businesses are less entrepreneurial on average, especially after the founder departs. Despite agreement on the importance of adopting governance structures and mechanisms for the survival of family businesses, there is still a lack of togetherness or cohesion among the family members across generations, which leads to confusion and conflicts and poses a serious threat to the sustained growth and long-term survival of the business. The aim of this paper is to explore the role of family constitution for transgenerational entrepreneurship in family businesses by examining how family governance practices can contribute to strengthening the transgenerational entrepreneurship. In this regard, family constitution of a family owned business located in İzmir, was examined and in-depth interviews and exploratory case study analysis from qualitative research methods were applied.

Published: April 2021

The article presents the results of an epidemiological study of the prevalence and intensity of inflammatory periodontal diseases (IPD) in the northern and southern parts of Ufa, as well as the need for complex periodontal treatment. The number of visits by primary persons for periodontal care in the NW is 2.1 times less than in the SW. The rank values of common risk factors for the development of IPD have been identified. When assessing the KPI index, the risk to this pathology and its difference in different parts of Ufa, taking into account the nosological form and gender, were identified. With acute gingivitis, men living in NW and SW were statistically equally treated to a periodontist, while women living in NW were 1.8 times more. With acute periodontitis in the NW, men visit a periodontist 1.9 times more than in the SW, and women, on the contrary, in the SW are 1.2 times more likely to visit than in the NW. With chronic forms of IPD, the differences in treatment among men and women were not statistically significant and did not depend on the area of residence.

Authors: Othman Najwa Karmila , Buang Nor Aishah
Published: April 2021

The homestay industry is part of the tourism services industry. It is important for homestay operators to provide services that can meet the needs and satisfaction of customers. However, there are some problems related to the quality of services provided by homestay operators that affect customer satisfaction. Problems arise due to a lack of knowledge of the dimensions that can be used to provide quality services. There are five dimensions of the SERVQUAL model that are associated with service quality characteristics and are able to influence homestay customer satisfaction, namely tangible, empathy, responsiveness, reliability, and assurance. This study was conducted with the aim of finding out the relationship between the five dimensions of SERVQUAL service quality with homestay customer satisfaction and identifying the dimensions that most affect customer satisfaction.

Authors: Iswara Candice , Rahadi Raden Aswin
Published: April 2021

Bubble tea currently represents a popular drink among Generation Z in Indonesia. Their quality varies according to intrinsic and extrinsic aspects that can sometimes be modified to make it more desirable. As consumers are the final economic activity actor in the production chain, it is beneficial to identify which factors affect their behavioural patterns. This fact would allow the bubble tea shop owners to satisfy better consumer expectations, demands, and needs. This paper focuses on features that might influence consumer behaviour, preferences, and perception of bubble tea beverage and determine any differences in bubble tea purchasing power. The research will use a quantitative approach by distributing questionnaires to Generation Z and analyzing several aspects: price, taste, product design, brand influence, and location accessibility.

Published: April 2021

Lake Tondano is the largest natural lake in North Sulawesi, Indonesia, which functions as a provider of clean water, hydroelectric power, rice field irrigation, inland fisheries, and tourism. This research aims to determine the effect of land cover types from the Tondano watershed on the lake water quality. The Soil and Water Assessment Tool (SWAT) model was used to evaluate the rate of soil erosion and the pollutant load of various land types in the watershed during the last ten years. Rainfall data is obtained from two rainfall stations, namely Paleloan Station and Noonan Station. The model is calibrated and validated before being used for analysis. We use climatological data from 2014 to 2019. The process of the SWAT model calibration and validation was carried out with the statistical formulas of the coefficient of determination (R2) and Nash-Sutcliffe efficiency (NSE). The results show that the potential for pollution load from the Tondao watershed is organic N of 0.039 kg/ha and organic P of 0.006 kg/ha coming from the agricultural land. The results of this study conclude that the fertility conditions of Lake Tondano are at the eutrophic level, where the pollutant inflow is collected in the lake waters, especially for the parameters of total N (1503697.44kg/year) and total P (144831.36kg/year). The SWAT simulation results show deviation between the modeling and field data collected with the value of R2 = 0.9303, and the significant level ≤ 10.

Indonesia has implemented the National Health Insurance (JKN) program since 2014. The Corruption Eradication Commission (KPK) detected fraud in the program, which causes state losses. Prevention by the Social Security Administering Bodies (BPJS), law enforcers, and health care facility providers (faskes) has proven not optimal yet. This study aims to determine the effect of Information Technology Innovation and Organizational Culture on fraud prevention in the Regional General Hospitals (RSUD) in Sumatra with a total sample of 421 respondents. This study applies a quantitative approach and uses a questionnaire instrument in collecting research data. The results showed that Information Technology Innovation and Organizational Culture affected fraud prevention. The results of this study proved that in public sector organizations, the level of fraud could be prevented by Information Technology Innovation and Organizational Culture.

The study aims to identify social media's role in shaping university youth's attitudes towards the knowledge economy's requirements, and the study belongs to the descriptive studies. The study conducted a survey on a sample of 400 individual adolescents by using questionnaire form. The study concluded that social media has contributed to the development of the knowledge economy by being an important source for obtaining information about the knowledge economy, directly contributing to the formation of awareness among individuals, working to raise the level of knowledge economy culture among community members, and working on forming specific trends for the individual towards knowledge economy requirements. The most important participation mechanisms that it undertakes through social media to spread the requirements of the knowledge economy is to interact with pages interested in transmitting news of the knowledge economy, publishing pictures, posts or news related to the knowledge economy in society, commenting on issues related to the knowledge economy. The most important obstacles to the requirements of the knowledge economy through social media are represented in the following: the lack of mechanisms for developing knowledge behaviors among young people, the lack of awareness of the knowledge economy culture in action and content, the lack of proficiency in the use of information and communication technology, the violation of the intellectual property rights of knowledge, the destruction, destruction or theft of electronic websites.

Published: April 2021

Herein, we report on a photoluminescence (PL) method for evaluating the Mg acceptor concentration in GaN, which has thus far been difficult and costly to determine using conventional electrical methods. The proposed method is based on the intensity ratio between the acceptor bound exciton emission and free exciton emission in the PL spectra of GaN. The calibration curve for the Mg acceptor concentration ranging from 6.4 × 1016 to 1.2 × 1018 cm−3 was obtained from the concentration dependence of the PL spectra recorded at 40 K. Furthermore, the detection limit of the Mg acceptor concentration from this method was estimated to be approximately 1010 cm−3. Results indicate that our method enables the unambiguous, simple, low-cost, and nondestructive quantification of the Mg acceptor concentration of p-type GaN, which is important in power device applications.
КОННОТАТИВНЫЙ ХАРАКТЕР НАИМЕНОВАНИЙ ДОМАШНИХ ПТИЦ В РУССКОМ И УЗБЕКСКОМ ЯЗЫКАХ
Authors: LATIPOV Okil
Published: April 2021

Зоонимический пласт лексики всегда представлял для исследователей большой интерес, так как несчетное количество метафорических выражений, связанных с названиями животных, составляют богатство и неповторимость каждого языка. В частности, класс слов, обозначающих наименования птиц, характеризуется своим разнообразием, богатством коннотаций. Данная статья посвящена изучению семантической структуры орнитологической лексики русского и узбекского языков. В ней раскрыты коннотативные значения наименований домашних птиц в составе устойчивых сочетаний слов разносистемных языков, приведены примеры их функционирования в текстах художественной литературы, а также выявлены соответствия клишированных единиц с ключевым словом-орнитонимом в двух данных языках. Для решения данной задачи в ходе исследования были применены метод компонентного и статистического анализа. Если метод компонентного анализа позволил изучить коннотативные значения слов-орнитонимов в составе клишированных единиц двух сопоставляемых языков, то метод обработки статистических данных способствовал определению количественного состава образных выражений с названиями домашних птиц в разносистемных языках. Практическая значимость материалов данной статьи заключается в совершенствовании некоторых вопросов межкультурной коммуникации, а также переводческой практики текстов художественной литературы с одного языка на другой.
