“…Venting holes are arranged in the transverse walls separating the pools, which are located alternately at the right, then at the left walls (for sturgeon -at the bottom; for carp -near the surface). And also, to increase the efficiency of attracting fish, additionally, on both sides of the stepped trays, a transit part is made in the form of a rapid flow for large fish that are accustomed to independently climbing up on a smooth surface [24][25][26]. Figure 5 shows the diagram of the fishpassing facility in the form of stepped trays and the 2-2 transverse section of the stepped tray.…”

Fisheries are an important economic component of the Republic of Kazakhstan, covering an area of 25.475 hectares throughout the country. However, fish are threatened by natural and artificial obstacles such as heavy rains, droughts, floods, and electricity consumption. Although fish enclosure structures can offer protection, designing new, more efficient fish-passing facilities is crucial. This study aimed to develop a model for a fish-passing facility, with experiments conducted at the Dulati Taraz Regional University in the laboratory of hydraulic structures and land reclamation. Researchers built a laboratory model of the facility and compiled an analytical model of the proposed technical solution. The study calculated the optimal values of the additional pressure and axial velocity of the total flow based on the required attracting flow. The practical significance of this research is in the ability to create a controlled high-speed flow regime in the fish-passing tract, which would provide favourable conditions for the passage of different types of passing and semi-passing fish through the hydroelectric facility dam, despite significant fluctuations in the headwater levels. The scientific nature of this research is evident in its contribution to the broader knowledge base in the field of fisheries and ecological engineering. The study expands our understanding of fish behaviour and provides new insights into the design of fish-passing facilities.

“…Thus, the water quality assessment according to hydrobiological indicators corresponded to classes 3 and 4, moderately polluted and polluted water in various sections. In water systems with a diverse range of uses, the water quality assessment should be carried out on a set of chemical and biological indicators, taking into account the intake of organic compounds and pollutants that have toxicity [25,36]. Table 9 gives an assessment of the Yesil River waters quality by a set of indicators in accordance with the unified Gold's Classifier [26].…”

This study provides an in-depth characterization of the water quality in the Yesil River in the Astana region for 2019, utilizing hydrochemical parameters and key indicators of bacterioplankton, zooplankton, and zoobenthos. Quantitative evaluation methods were employed to assess hydrobionts, including total bacterial counts, heterotrophic bacterial counts, bacterial multiplication rates, biomass, and abundance of zooplankton and zoobenthos, in addition to species identification for various organisms. The results indicated that, based on the bacterioplankton development level, the investigated section of the Yesil River is classified as a mesotrophic water body. As the river flows through the city, the average bacterial mass doubling time decreases due to an increase in the proportion of heterotrophic bacteria. Based on the saprobity index level for the zooplankton community, the water in the Yesil River is categorized as moderately polluted. Macrozoobenthos saprobity indices range from moderately polluted to polluted waters. The final assessment of the water quality classification and contamination degree, according to Z.G. Gold's unified classifier, revealed a shift from class 3 in the sections upstream of Astana to class 4 in sections downstream of the city.

“…The authors of the current study note that the use of microorganisms in biotechnologies is a promising approach for the treatment of industrial wastewater, but caution that careful monitoring is needed to prevent the development of antibiotic resistance. The ability of microbes to quickly acquire resistance to antibiotics requires monitoring their use and finding new means to combat their reproduction [21]. Thus, substances of natural origin are able to regulate the ratios of groups of microorganisms in microbiocenosis.…”

This study aims to explore the potential of new microorganisms for bio-purification of polluted reservoirs in Northern Kazakhstan. Through laboratory experiments involving field collection of hydrobiological samples and screening of new strains of microorganisms, the study suggests that biological purification using organic and inorganic compounds found in polluted waters as a nutrient medium is the most effective method. This research contributes to the development of effective strategies for addressing pollution in Northern Kazakhstan's water resources and highlights the potential of using microorganisms as a tool for environmental remediation. The significance of the research lies in the fact that it proposes a solution to the issue of pollution in reservoirs in Northern Kazakhstan through the introduction of new strains of microorganisms, contributing to the development of effective strategies for improving water quality and minimizing the negative impact of pollutants on the hydrosphere.
