Abstract
This study was carried out between November 2013 and May 2015, to determine the fish fauna inhabited in the Atatürk Dam lake. The specimens were obtained by different technical fishing gears. It was determined that specimens caught were belonging to 25 species (Capoeta trutta, Capoeta umbla, Cyprinon macrostomus, Arabibarbus grypus, Carasobarbus luteus, Carassius carassius, Carassius gibelio, Cyprinus carpio, Garra variabilis, Luciobarbus esocinus, Luciobarbus mystaceus, Luciobarbus xanthopterus, Acanthobrama marmid, Alburnus mossulensis, Chondrostoma regium, Leuciscus vorax, Squalius cephalus, Cobitis elazigensis, Mystus pelusius, Silurus glanis, Silurus triostegus, Glyptothorax kurdistanicus, Oncorhynchus mykiss, Mastacembelus mastacembelus, Planiliza abu) and 8 families (Cyprinidae, Cobitidae, Bagridae, Siluridae, Sisoridae, Salmonidae, Mastacembelidae, Mugilidae) were identifed. The most dominant family in the Atatürk Dam Lake is the Cyprinidae with 17 species and eightteen species within 25 species that were identified have commercial value. The existence of Silurus glanis, Mystus pelusius and Carassius carassius was determined for the first time in Atatürk Dam Lake and they are new records for the lake.
Highlights
Recent documentations on the number of species in the inland waters ichthyofauna of Turkey indicates that further studies would establish better inventory. (Kuru, 2004), 236; (Ronald et al, 2007), 261; (Kuru et al, 2014), 371 and (Çiçek et al, 2015) reported the number as 368
As the result of this study it was determined that 25 species belonging to eight families exist in Atatürk Dam Lake
This means that 6.5% of ichthyofauna repoted from Turkey by (Çiçek et al, 2020) is present in the dam lake
Summary
Recent documentations on the number of species in the inland waters ichthyofauna of Turkey indicates that further studies would establish better inventory. (Kuru, 2004), 236; (Ronald et al, 2007), 261; (Kuru et al, 2014), 371 and (Çiçek et al, 2015) reported the number as 368. Recent documentations on the number of species in the inland waters ichthyofauna of Turkey indicates that further studies would establish better inventory. It was claimed to be 384 in the latest report (Çiçek et al, 2020). The total of these 384 fish species belong to 20 orders and 34 families in the inland waters of Turkey. Atatürk Dam Lake constructed on 2800 km long Euphrates River, of which 1263 km part is the territory of Turkey, is ranked as the largest in Turkey and one of the most prominent ones in the world. The dam lake is 180 km long and covers an area of 817 km at maximum management level. Having a great contribution to the diversity of species in its zoogeographical region thanks to its large reservoir and having a special importance by sheltering localized fish species such as Arabibarbus grypus, Silurus triostegus, Mastacembelus mastacembelus, Mystus pelusius, Garra variabilis, Glyptothorax kurdistanicus, Capoeta trutta, Capoeta umbla, Planiliza abu it has great potential for fisheries due to large water carrying capacity
