Abstract

Buyuk Menderes River basin, located in the Southern part of Turkey, has two significant dam lakes. Threats include pollution (industrial and agricultural activities), overfishing, habitat degradation and drought. This study was carried out to determine the native and non-native fish fauna in Kemer and Topcam dams lakes in the Buyuk Menderes River. Specimens were caught by scoop and gill nets between April 2007 and February 2008. Kemer is inhabited by Cyprinus carpio, Squalius cephalus, Barbus plebejus escherichi, Silurus glanis Acanthobrama mirabilis and Chondrostoma maendrense. In Topcam Dam has Cyprinus carpio, Squalius cephalus, Acanthobrama mirabilis and Capoeta bergama. Both had the invasive Lepomis gibbosus, Pseudorasbora parva and Carassius gibelio. Acanthobrama mirabilis is endangered fishes and Chondrostoma maendrense and Capoeta bergamae are two of the vulnerable species.KEY WORDSKemer, Topcam Dam Lake, Native, Exotic fish, Anatolia.

The invasion of non-native fish species is accelerated by human activities in last few decades all over the word
In Anatolia, biodiversity freshwater fish is rich with 213 species owing to its zoogeographic location

Summary

Introduction

RESUMEN La cuenca del Río Buyuk Menderes, situado en la parte sur de Turquía, cuenta con dos embalses importantes. Este estudio fue realizado para determinar la fauna de peces nativos y no nativos en los lagos de los embalses Kemer y Topcam en el río Buyuk Menderes de la parte sur de Turquía, suponiendo que los peces indígenas afectados están siendo afectados por los peces exóticos. Se identificó que en el embalse Kemer se cuenta con especies de Cyprinus carpio, Squalius cephalus, Barbus plebejus escherichi, Silurus glanis Acanthobrama mirabilis y Chondrostoma maendrense. The invasion of non-native fish species is accelerated by human activities in last few decades all over the word. A total of 25 exotic fish species have been introduced in Turkey as fry or fingerlings for different purposes over the last decade as compiled by Innal and Erk’akan (2006). One of global problems is the biodiversity of freshwater systems has deteriorated as a result of human activities
