“…Indicators of ecological health based on biological communities are widely used to assess and report the condition and status of aquatic ecosystems [70]. Changes in the structure of the ecosystem can affect the functioning of the system and can result in the loss of economic and ecological values [55], therefore, it becomes very important to consider the impacts of environmental variability.…”

Multiple stressors, such as overfishing, pollution, climate change, biological invasions etc., are affecting fish communities, and thus can have versatile effects on marine ecosystems and socio-economic activities as well. Understanding the changes in the fish community structure is ecologically and economically important, yet a very complex issue, requiring comprehensive analysis of multiple factors. The role of regional oceanographic variability, namely, coastal upwelling, is often neglected when it comes to the analysis of fish assemblages. In this perspective, we were aiming, for the first time in the Baltic Sea, to assess the upwelling influence on fish communities and fish community-based ecological indices used under Marine Strategy Framework Directive. The study covered a long-term period (2000–2019) for upwelling identified by satellite data analysis and fish gillnet surveys, performed in three distinct locations in the coastal waters of the SE Baltic Sea. Overall, our study revealed that temporal dynamics of fish abundance and community composition were associated with the presence of coastal upwelling. The study outcomes suggest that the fish community was more diverse and a higher number of some fish species was observed before upwelling. During upwelling, there was more evident dominance of 1–2 main marine fish species. Through the changes in fish abundance and species composition upwelling was also responsible for the changes in fish community structure-based indices for marine environment status, i.e., in the majority of the cases a decrease in Trophic, Piscivorous Fish, and Diversity indices were observed. Our study demonstrates that upwelling can affect both, the quantitative and qualitative characteristics of coastal fish communities, therefore, it is important to consider this when predicting shifts in the distribution of fish stocks or assessing environmental status indicators, especially under changing climate. We believe that our approach adds novel information to the study of coastal ecosystems of the Baltic Sea and is important for better management of socio-economic activities in the coastal zone.

“…The internationalization process is a dynamic concept, namely the process of adding internationalization operations both externally and internally (Hallett, 2012). The internationalization process is the process by which companies raise awareness of the direct and indirect impacts of future international transactions, and establish and conduct transactions with other countries (Kaukab, 2017).…”

This study aims to discuss the strategy and role of the government in the internationalization of MSMEs. The research method used in this study is a qualitative descriptive method. The type of data used in this research is qualitative data, which is divided into primary data and secondary data. Sources of data obtained through library research techniques that refer to resources available online and offline, such as: scientific journals, books, and news from trusted sources. The results showed that the internationalization strategy conceptually and theoretically can be divided into two categories, namely internationalization theory and selectivity theory. The emergence of internalization theory can threaten the existence of MSMEs due to the development of large companies in the 1970s. Furthermore, in its development, the theory seeks to internalize the benefits that can be obtained from internationalization, localization, and ownership. At the same time, the eclectic theory in the internationalization strategy places more emphasis on the resources owned by MSMEs and knowledge of the markets and networks that MSMEs choose to market their products. The steps taken by the current government by creating a special portal at INSW are appropriate, but if this is achieved not only through existing portals, but also through direct engagement with business people, including through seminars and workshops by interacting with them more often and socialize.

“…Although there are many biological assessment methods using various taxa as such, the index of biological integrity (IBI) [24] assessment method using fish is representative. In this regard, in overseas countries, Cabral et al [25] developed an estuarine fish assessment index (EFAI) using fish according to the characteristics of the Portuguese estuaries and conducted overall assessments of brackish water zones, and Hallett et al [26] assessed brackish water zones using the fish community index (FCI) for efficient estuary management in Australia.…”

Brackish water zones are areas with high ecological conservation value. In this study, 325 river estuaries in the Korean peninsula in individual sea areas (West Sea, South Sea, and East Sea) were divided into types of estuaries (upstream and downstream of open estuaries, closed estuaries) through the assessment of the health of the estuary aquatic ecosystems and fish communities were identified. An ecological assessment was carried out using the Korea Estuary Fish Assessment Index (KEFAI). The number of species increased as the size of the river increased in the case of small estuaries but gradually decreased in the case of large estuaries. In the closed estuaries, the relative abundances (RAs) of primary freshwater fish were the highest; however, in the open estuaries, the RAs of estuary fish were the highest. Non-metric dimensional analysis results suggested that there was a clear difference between the fish assemblages in the closed and open estuaries. The overall results of this study were that the RA of tolerant species was higher, and KEFAI was lower in closed estuaries than in open estuaries, indicating the negative effects of the construction of transverse structures on fish assemblages. The health of these estuarine ecosystems can be improved by addressing these negative effects.
