dc.description.abstractIn the present study, 36 fish species have been recorded from Ottu reservoir which belongs to 26 genera, 12 families and 5 orders. The Cyprinidae family was predominant among the 12 families. The IUCN conservation status of fishes at Ottu reservoir have shown that the most of the species i.e. 61.11% felled under Least Concern (LC) category (22 species) followed by 13.88% under Near Threatened (NT) group (five species) as well as Not Evaluated (NE) group (five species) and the two species found as vulnerable (VU) and one as endangered (EN) i.e. Tor putitora. The study on various physico-chemical properties of Ottu reservoir have shown that the water quality of Ottu reservoir was polluted due to increasing level of organic and inorganic compound which is discharge from the industrial effluents. The most of the water parameters ranged under normal as per optimum value for aquaculture. However, some of them were ranged higher than their optimum value i.e. alkalinity, ammonia, TDS, hardness chloride and salinity indicated that the level of pollution in Ottu reservoir. From the above point of view, it could be concluded that the water of Ottu reservoir need to be treated before its utilization for drinking and should be improved for aquaculture purposes. The soil texture of Ottu reservoir found that 43.33% clay, 21.67% silt and 25% sand which could be fallen under class of clay loamy soil. The soil pH of Ottu reservoir was generally neutral which is ranged from slightly acidic (pH= 6.5) to slightly alkaline (pH= 8) at different sites of Ottu reservoir. The present study gives enlightening information on fish bio-diversity and assists on understanding the water nature of Ottu reservoir. The fish-biodiversity of Ottu reservoir was narrow which indicated the enrichment in fish diversity through improving their water qualities and need to be conserved the vulnerable and endangered fishes of Ottu reservoir through suitable conservation strategies.en_US
