Abstract

A three samplings were carried out between September 2014 and August 2015, at twelve stations to determine the seasonal changes of species, relations with water quality parameters, and the Malacostraca fauna of the Upper Coruh River Basin. A hand net was used to collect the biological samples. Dissolved oxygen, temperature, pH, electrical conductivity, and total dissolved solids were measured using a portable water meter. Nitrite, ammonium, phosphate, and biochemical oxygen levels were also measured. Seven taxa were identified (five of them belong to Amphipoda, one to Isopoda, and one to Decapoda). Gammarus birsteini was the continuous, while G. kischineffensis and Asellus aquaticus are common. G. fossarum, G. balcanicus, Gammarus sp. and Potamon ibericum were rarely found. AF (Aydıncık Foundation) and DF (Değirmencik Foundation) stations had first class water quality while other stations had second and third quality according to the Quality Criteria According to Classes of Inland Water Resources.

Freshwater Amphipod Species of Western Anatolia, Marmara and Turkish Thrace Regions

“…In Turkey, it was first recorded from the Erciyes Mountain by S. Karaman (1934). Then, it was reported from several localities from the Strandja Mountains in Thrace to Bayburt in the Black Sea region, from İzmir in the Aegean to Hatay on the Mediterranean coast and to Van in eastern Anatolia (Akbulut et al, 2009b;Akbaba & Boyacı, 2015;Aygen & Balık, 2005;Balık et al, 2006;Baytaşoğlu & Gözler, 2018;Chertoprud & Palatov, 2017;Ekinci & Miroğlu, 2016;İpek et al, 2017;Karaman, 2003, Karaman & Pinkster, 1987Öntürk & İpek, 2018;Özbek & Ustaoğlu, 2005Özbek & Ustaoğlu, , 2008Özbek & Ustaoğlu, , 2011Özbek et al, 2004Ustaoğlu et al, 2004Ustaoğlu et al, , 2008. In this study, the species was recorded from the Kocaeli and Sakarya provinces for the first time.…”

“…It flows into the Black Sea by the delta formed by alluviums it carries from Batumi, the capital of Ajara, which is the semiautonomous province of Georgia. A large part of the drainage area (91%) is located within the borders of Turkey, and the rest (9%) is located within the borders of Georgia (Akpınar et al, 2009;Baytaşoğlu and Gözler, 2018). The total length is 466 km.…”
