In the myxosporeans fauna of greening fish, 6 species of myxosporeans were found: Sphaeromyxa hexagrammi, Zschokkella russelli, Ceratomyxa azonusi, Alataspora bialata, Kudoa azoni, Kudoa sp. At the same, three species (S. hexagrammi, C. azonusi, K. azoni) are specific only to greenling fish. Two species (Z. russelli, A. bialata) are broadly specific, Kudoa sp. not determined to species It was established that in the common greenlings the infection with myxosporeans was low, and the composition of the fauna was poor. The one-finned greenlings, in contrast to the common-finned greenlings, were more infected and had more myxosporeans species in their fauna. But both greenlings are dominated by the gallbladder species Sphaeromyxa hexagrammi, and muscle parasites of the genus Kudoa (K. azoni, K sp.), but the nature of infestation and distribution across the study areas are very different. First of all, with the biology of these greenlings. A smaller degree of differences in the common greenlings in the expansion of invasion by various species of myxosporeans less ecological plasticity of these species, compared to the single-finned greenlings.","PeriodicalId":507926,"journal":{"name":"Fisheries","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139259380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ichthyofauna of the Dnieper River within the surveyed area did not differ in species diversity: 10 species of fish belonging to the families Cyprinidae (Cyprinidae) and perch (Percidae) were identified. Roach (Rutilus rutilus) dominated, the subdominants were chub (Squalius cephalus) and perch (Perca fluviatilis). The average oligochaete index, ranging from 21 to 50%, characterizes the waters of the river as slightly polluted and belonging to class II quality. The composition of phytoplankton was dominated by diatoms and green algae. As part of zooplankton, representatives of the genus Brachionus dominated among rotifers, and crustaceans of the genus Bosmina dominated among branchiformes. The composition of zoobenthos was dominated by larvae of chironomids, subdominants – oligochaetes. The Dnieper River within the borders of the Smolensk region, according to our data, is characterized by the level of development of phytoplankton and zooplankton as a \"low-feeding\" area for phytophagous fish and zooplanktophages, and by the level of development of zoobenthos as a \"high-feeding\" area. The ichthyofauna of the studied area is characterized by the presence of predatory and omnivorous fish, the presence of phytophages and zooplanktophages is not characteristic, which may be due to the peculiarities of the state of the natural food supply.","PeriodicalId":507926,"journal":{"name":"Fisheries","volume":"20 1-2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139259442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
