Abstract:   (241 Views)
Iran is located in a region that is very important in terms of animal geography, but there is little information about its fish fauna, which is very interesting and diverse. In the present research, biodiversity was calculated with Shannon-Wiener, Hill, Pilou and Margalf indices for Kashkan and Seymareh rivers in Poldakhtar city in Lorestan province. Sampling was taken in seven stations and 389 pieces of fish belonging to 15 species of carp, dogfish, catfish and snake fish families were caught and identified. Biodiversity values ​​obtained for Shannon-Wiener, Hill, Pilou and Margalf indices in the downstream of the confluence in the first sampling, respectively were 2.38, 10.64, 0.99, 2.7 And in the second sampling, 2.28, 9.63, 0.95, 2.86, and in the third sampling, 2.4, 10.85, 0.94, and 3.82 were obtained and in the Kashkan river, respectively In the first sampling 1.55, 4.7, 0.79, 1.99 and  in the second sampling 1.2, 3.3, 0.62, 2.5 in the third sampling 1.44 and 4.18 and 0.81, 4.39 were obtained, and in the Symareh river, respectively, in the first sampling, 2.08, 7, 0.85, 2.75, and  in the second sampling, 1.92, 6.8, 92. 0, 2.5 and in the third sampling, 2.02, 7.5, 0.88, 3.6 were obtained that the results obtained from this research showed the greatest biodiversity in the downstream area of ​​the confluence of two rivers, Kashkan and Seymareh.
