“…The analysis of the table shows that the basis of roach nutrition in the Tobol River is food of plant origin. As previously stated, the development of zooplankton and zoobenthos in the river is low, and given the presence of a significant number of competitors in this spectrum, it is natural that this species, having a relative unpretentiousness in nutrition, will choose the most available food, in our case it is aquatic vegetation [25][26][27]. Thus, in the roach of size groups from 6 to 14 cm, the share of food of animal origin does not exceed 21.5%, in the size group 19-22 cm this figure increases to 39.3%.…”

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.

“…The disease affects mainly fish belonging to the carp family: tench, bream, roach, roach, taran, redfin, crucian carp, goose, gustard, bleak, and some others. The disease affects fish more often in shallow bodies of water with a slow current, and less often in rivers with a fast current (Maira et al, 2020). The shallow depths of rivers and lakes, slow currents, and extensive aquatic vegetation contribute to the intensity of infestation.…”

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.

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.
