“…When analyzing the reasons for the discrepancy between the survey results and the literature data on the incidence of anisakidosis in the territory of West Kazakhstan oblast, it can be assumed that this is due to the different locations of fish catches. As one of the hosts in the development cycle of the parasite is the Caspian seal, which lives only in seawater, it is logical to assume that infestation of fish can only occur in those bodies of water that have contact with the sea (Ye Kyrychuk and Muzyka, 2016).…”

Control fish catches in the reservoirs of the Ural-Kushum water-irrigation system and the Derkul, Ankaty, Shiderta, Buldyrty, Utva, and Rubezhka rivers allowed the establishment of the extensiveness and intensity of infestation by the main helminth species among fish and the studied reservoirs. Ligulosis pathogens had the highest prevalence in the territory of West Kazakhstan region, found in 5 of 9 surveyed reservoirs, and postodiplostomosis in 4 of 9. Diseases were registered predominantly among carp family fish, and the extensiveness of infestation was 4.1 and 3.2%, respectively, of the total number of fish. The main species in which helminths have been detected are redfin, roach, and goose. Among anthropozoonotic diseases, in which fish are intermediate hosts, individuals with opistorchosis metacercariae were found in Derkul and Rubezhka rivers. The extensiveness of infestation was 16% of the carp population, which was significantly lower than the results of earlier studies. Of the other diseases dangerous to humans, no anisacid larvae were detected, which also did not agree with literature sources. Parallel to the parasitological examinations of fish, an examination of caught crayfish was carried out to determine the number of diseased crayfish. The survey revealed that about 20% of the river crayfish caught in the reservoirs had signs of rust-stain disease.

“…Прісноводні молюски належать до різних екологічних груп гідробіонтів, досить різноманітні за своїми екологічними спектрами, функціональними та фізіологічними властивостями. Вони слугують тест-об'єктами під час екологічного моніторингу навколишнього середовища, бо здатні вилучати в індикаторних кількостях із довкілля та накопичувати у своєму організмі радіонукліди, різні макро-та мікроелементи, токсичні речовини неорганічного та органічного походження тощо (Kyrychuk, 2006;Kyrychuk and Muzyka, 2015;Kyrychuk and Muzyka, 2016). Саме черевоногі молюски являють собою таксономічно різноманітну, екологічно пластичну та досить розповсюджену групу гідробіонтів, роль яких у житті прісноводної екосистеми величезна (Orvain and Sauriau, 2002;Stadnychenko et al, 2005;Sitnikova et al, 2010).…”

Ecological and geographical characteristics of algal communities on gastropod shells of the river Uzh

Freshwater molluscs serve as test objects in the ecological monitoring of the environment, because they are able to extract in indicator quantity from the environment and accumulate in their bodies radionuclides, various macro-and micronutrients, toxic substances of inorganic and organic origin, and so on. The gastropods are a taxonomically diverse, ecologically plastic and rather widespread group of aquatic organisms, whose role in the life of freshwater ecosystems is very important. Molluscs often have various interactions in biogeocenoses that determines their trophic net. As a rule, these interactions occur in the form of ectocommensalism, endocommensalism, supercrescence, predation or parasitism. The latter type of interaction is the subject of many studies, but the epibionts of gastropods and bivalves are practically not studied and that causes the relevance of the research. Species composition of algal epibionts identifies specific sensitivity to the effects of certain environmental factors and reflects the processes occurring in water bodies of its ecosystem. This determines their efficient use for analyzing changes of water bodies, particularly in terms of complex anthropogenic pressure on aquatic ecosystems, as aquatic habitat. The aim of the research was to determine the ecological characteristics of algal communities on gastropod shells: Lymnaea stagnalis, L. auricularia and Viviparus viviparus (the Uzh river, Korosten district, Zhytomyr region). Identified microalgae communities were grouped and studied according to such indices as: confinedness to the habitat (substrate), temperature, fluidity and water oxygenating, saprobiological characteristics according to the Pantle-Buck system in the modification of Sladecek and Watanabe, salinity according to Kolbe's system, pH at Hustedt scale in the interpretation of M. M. Davydova and geographical confinedness of objects of study. Algae fouling on shells L. stagnalis, L. auricularia and V. viviparous are formed by benthic and benthic-planktonic species. Algal epibionts of studied communities are mainly confined to slowflowing waters. The basis of a floristic list according to the temperature in all studied groups of gastropods formed indifferent species. According to geographical distribution of algae fouling cosmopolitan species dominated. In relation to salinity according to Kolbe's system, most discovered species were indifferent oligo-galob. Algal communities are reliable indicators of one of the important indices of watercourse hydrochemical conditions-pH of water. Analysis of algal epibionts on gastropod shells of the river Uzh, showed the dominance of alkaliphiles and indifferent species (from the number of identified microalgae). According to saprobiological characteristic of water quality of the river Uzh predominance of o-saprobes. Analysis of indicator groups showed that the most numerous algal epibionts on shells were euresaprobe species. A detailed ecological and geographical characteristic of algae fouling on shells of studied groups of mollu...

“…The Tobol River flows through various natural areas, including steppes, forest-steppes, mixed forests, and southern taiga, before joining the Irtysh River. Within the Tobol basin, approximately 20,000 lakes collectively cover an area of 9,000 square kilometers, providing the foundation for the ecosystem of Northern Kazakhstan and the neighboring regions of Southern Siberia [5]. The river serves as a vital waterway for the region, catering to transportation, fishing, and agriculture, while also offering recreational activities such as fishing and rafting.…”

“…Ten hydroelectric stations operate within the Tobol River basin, and the water quality of the river and other water bodies in the region is negatively impacted by the discharge of industrial and domestic untreated or insufficiently treated wastewater [5]. Additional detrimental factors include the washout of fertilizers and other pollutants from agricultural fields and land during spring floods and summer rain floods, as well as the substantial amount of pollutants emitted into the atmosphere near the river.…”

The Tobol River, a nationally significant economic water body, serves various purposes and spans across diverse landscape zones and environmental conditions. An evaluation of the forage base development of the Tobol River was conducted through the survey of six stations along the river in 2019. The investigation revealed a total of 15 species of planktonic invertebrates, including 6 rotifers, 5 cladocerans, and 4 copepods, as well as 28 species of benthic organisms. The survey period of 2016-2019 registered 36 species and forms of benthic organisms within the Tobol River basin, with a high diversity of insect groups. The considerable length and varied landscape zones of the river contribute to the observed high diversity of organisms. In terms of zooplankton development, the Tobol River exhibits a moderate food supply class and, according to S.P. Kitayev's trophic scale, can be classified as a β-mesotrophic water body. Similarly, the river's zoobenthos development indicates a moderate food supply class, designating it as an αmesotrophic type under S.P. Kitayev's trophic classification. The study of the food spectrum of river perch and roach in the Tobol River suggests relatively high food availability for these species, underscoring the importance of understanding the ecological and biological forage base of the river for maintaining ecosystem health.
