Abstract

In order to determine the Mollusca fauna of species in Akyaka Azmak Stream. seasonal samplings were made from 2 stations between September 2008-May, 2009. After collecting benthic materials by using a hand-net with 500 mu m mesh size and Ekman grab, after shed, they fixed in 4% formalin solution. As a result of study, totally 10 taxa were determined; all of them belong to Gastropoda as Galba truncatula, Theodoxus anatolicus, Theodoxus fluviatilis, Theodoxus heldreichi, Gyraulus albus, Potamopyrgus antipodarum, Bithynia tentaculata, Bythinella byzanthina, Valvata cristata and Pseudamnicola roddail. The genera of Thedoxus is important for water quality. In the study, they are found very richness at the first station. Also, it has determined some phvsico-chemical parameter and discussed.
