Abstract
Today biodiversity conservation has its own significance in each region of the world. The investigation on fish’s biodiversity in Mordaghchay River of urmia basin aimed to determine the statues of fishes for the period 200810. Sampling in different ecological zones of river was done through Witton method from the headwater to estuary of river. Results show that there are 11 species of fish, belonging to 3 families Cyprinidae, Nemacheilidae and Salmonidae in the Mordaghchay River. The Cyprinidae family with 9 species compared to other families enjoyed high diversity. From a biogeographically point of view, in this river 64% of fish species (7 species) are native, exotic are 18% and also endemic species are 18%. In Mordaghchay river Acanthalburnus urmianus, Chalcalburnus atropatenae are endemic and their distributions limited to urmia basin. Maximum frequency of fishes with 44.85% is about Capoeta capoeta and minimum frequency with 2.06% is about Salmo trutta fario. Currently according to IUCN categories, Salmo trutta fario is considered as the endangered species, Acanthalburnus urmianus and Gobio persa as vulnerable, Chalcalburnus atropatenae and Oxynoemacheilus angora as conservation dependent species and Squalius cephalus are classified as near threatened species.
