Distribution Revised-Fifteen Years of Changes in the Invasion of a Freshwater Fish, Pseudorasbora parva (Temminck and Schlegel, 1846) in Turkey

Abstract

The aim of the present paper is to revise the distribution range of the invasive freshwater fish species, topmouth gudgeon Pseudorasbora parva (Temminck and Schlegel, 1846) in Turkey, based on the literature review. After the first report of the species from the Meriç River in Thrace (European part of Turkey) in 1982, it has spread across the country mainly through human-mediated accidental introductions. The species has now been reported from 66 water bodies in total. Besides the introduction pathways, we also present chronological distribution pattern of the species. This information is useful especially for conservation endemic ichthyofauna due to the negative impact of Pseudorasbora parva , particularly through introducing an emerging infectious eukaryotic intracellular pathogen on the fungal-animal boundary, Sphaerothecum destruens Arkush et al., 2003.
