| Summary: | A fish species prefer a particular habitat where provides its biological requirements, hence, understanding their habitat use and preferences are crucial for their effective management and protection. This study was conducted to assess the habitat use and selection patterns of Alburnoides namaki, an endemic fish in Jajroud River, Namak Lake basin, Iran. The river was sampled at 18 equally spaced sites. A number of environmental variables, including elevation, water depth, river width, river slope, velocity, substrate type, average diameter of bed stone, riparian vegetation type and total dissolved solid (TDS) and the relative abundance of A. namaki were recorded at each site. The results showed that A. namaki mostly selects upper parts of the river with higher slope, higher depth, lower width, lower velocity, bed rock substrate i.e. bed with boulder cover, TDS of 100-150 ppm, and deciduous forest and residential area riparian type compared with the available ranges. This study provides the habitat use and environmental factors affecting on the distribution of A. namaki in the Jajroud River. |
