Review of allochthonous fish species with the marine origin in Serbian freshwater system

Abstract

During the last decades in the freshwater system in Serbia 32 allochthonous fish species appeared, and they can be divided into five groups according to their region of origin: Asian, Ponto-Caspian, North American, South American, and Europe without Ponto-Caspian region. The Asian and Ponto-Caspian species are the most numerous. In the first group are representatives of fish fauna which are originally from Asia and they are intentionally introduced into open waters and aquaculture in Serbia, while the second group represents the migrants spreading their range from the Black Sea into freshwater systems. Some of these species already have established populations. Representatives of marine origin that inhabit freshwater systems in Serbia are: Syngnathus abaster, Neogobius fluviatilis, Neogobius melanostomus, Babka gymnotrachelus, Ponticola kessleri, Proterorhinus semilunaris, Knipowitschia caucasica, Benthophyllus stellatus, Gasterosteus aculeatus, Morone saxatilis x Morone chrysops. Gobiidae and Sygnathidae extended their geographical distribution outside their native range and expanded their area of distribution throughout whole Danube River Basin, while for the other specimens there are no literature data about established populations.

Tokom poslednjih dekada u rijekama i jezerima u Srbiji su se pojavile 32 alohtone vrste riba i prema regiji njihovog porijekla mogu se podijeliti u pet grupa: Azijske, Ponto-Kaspijske, Sjeverno Američke i Evropske bez Ponto-Kaspijskog regiona. Azijske i Ponto-Kaspijske su najbrojnije. U prvoj grupi su predstavnici riblje faune koji su porijeklom iz Azije i one su namjerno unesene u otvorene vode i akvakulturu Srbije, dok druga grupa predstavlja migrante iz Crnog mora koji šire svoj areal u sistemu rijeka i jezera. Neke od ovih vrsta su već uspostavile svoje populacije. Predstavnici morskog porijekla koji naseljavaju rijeke i jezera u Srbiji su: Syngnathus abaster, Neogobius fluviatilis, Neogobius melanostomus, Babka gymnotrachelus, Ponticola kessleri, Proterorhinus semilunaris, Knipowitschia caucasica, Benthophyllus stellatus, Gasterosteus aculeatus, Morone saxatilis x Morone chrysops. Gobiidae i Sygnathidae su proširile svoju geografsku distribuciju van nativnog areala i proširile distribuciju kroz cijeli bazen rijeke Dunav, dok za druge vrste nema literaturnih podataka o uspostavljenim populacijama.
