In this study the part of this river was demarcated into three streams (upper, middle and down). Five sites were selected from each stream. The water sample was collected at the depth of 10-15 cm in dry and rainy seasons into plastic bottles from each site of three streams for laboratorial analysis. The water sample was immediately analyzed by using titration method for water quality parameters like CO2, Chloride and alkalinity while water turbidity, temperature, water pH and Dissolved oxygen was taken onsite by direct measurements. Nitrite and ammonia were determined by using easy test kit. The result showed that alkalinity was high (66.3±39.1mg/L) at downstream and lowest(58±40mg/L) at middle stream. Concentration of CO2 is high (14±3.6mg/L) at the upper. The highest (28.7±2.6 mg/L) concentration of chloride was measured at downstream. pH value was ranged between 5.89-7.33 and the water temperature 23.4-26.2℃. The concentration of nitrite and ammonia were 0.01-0.04mg/L and 0.03-0.05mg/L respectively. The result showed that concentration of free carbon dioxide was significantly(P0.05). Generally, even though concentration of studied parameter varies within different streams along the river basins they are within the range of fish production.","PeriodicalId":31031,"journal":{"name":"Journal of Limnology and Freshwater Fisheries Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46261418","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}

In present study, a total of 26 planktonic microcrustaceans species, 14 from Cladocera and 12 from Copepoda were identified. The most common species in the reservoir were B. longirostris, D. pulex, D. cucullata D. galeata, D. longispina and D. brachyurum from Cladocera and C. abyssorum, C. vicinus, E. vulgaris and A. wierzejski from Copepoda. The annual mean microcrustaceans recorded during the study (24076 ind/m3) were recorded for Cladocera 67 % (16054 ± 12414 ind/m3) and Copepoda 33 % (8022 ± 5564 ind/m3). The maximum abundance of planktonic microcrustaceans were found in September (51521 ind/m3) and the minimum was found in January (2919 ind/m3). The environmental parameters measured in the reservoir was detected among the acceptable values to support aquatic life, especially the zooplankton community. The total microcrustaceans densities and abundance showed positive correlation with water temperature and Chlorophyll-a, while D. hyalina, D. cucullata, B. longirostris and C. ovalis from Cladocera and C. staphylinus, T. crassus, M. albidus, A. robustus, M. leuckarti, M. viridis and E. vulgaris from Copepoda were affected by similar environmental conditions.
