Invasive Fishes

In recent years, the topmouth gudgeon (Pseudorasbora parva) has been one of the most invasive fishes in Europe. Pseudorasbora parva can potentially affect ecosystems, fish communities, and particular fish species. Electrofishing was carried out over a five-year period at three study sites in the Ciemięga River (eastern Poland) before and after P. parva had been found in the river. Changes in the occurrence, abundance, and density of native fish species after the appearance of the invader were determined. Changes in the species’ richness were calculated, and correlations were estimated between the occurrence and density of P. parva and particular fish species and richness indices. The presence of P. parva has not affected the density of native species but coincides with a significant increase in estimated species richness and the total density of fish. There was a significant relationship between the presence of this invasive species and the fish community’s composition, though the PERMANOVA result was unclear with regards to site-specific effects. Moreover, tench and bleak were associated positively, whereas Eurasian perch and sunbleak were associated negatively with the occurrence of P. parva. Pseudorasbora parva density was highly correlated with Cyprinidae density (excluding P. parva), species richness, and the Margalef diversity index. Thise study has shown that the presence of predatory fish in the river (Salmo trutta L.) may reduce the numbers of invasive P. parva.

Alien Fish Species

<p>Substantial changes in the hydroecosystem of the Zaporizke reservoir have led to a significant transformation of aquatic<br />biocoenoses. As a result, number of some aboriginal fish species have decreased. The regulation of the Dnipro river has<br />contributed to the spread of new species of fish. Over the past 30 years, the ichthyofauna of the reservoir has gained about 20<br />species of fish that acclimatized and expanded their range. The article presents the results of ichthyological research of 2010-<br />2016. The article determines main causes of the spread of new species of fish, and gives the results of complex monitoring<br />studies on the number and biomass of young alien fish species of the Zaporizke reservoir. It was found that the most numerous<br />first summer individuals of alien fish species are big-scale sand smelt Atherina pontica (Eichwald, 1831), Prussian carp Carassius<br />gibelio (Bloch, 1782), topmouth gudgeon Pseudorasbora parva (Temminck et Schlegel, 1846), black-striped pipefish (Syngnathus<br />abaster Risso, 1826) and pumpkinseed Lepomis gibbosus (Linnaeus, 1758).</p>

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.
