Abstract
Alohtone vrste su oni organizmi koji se ne nalaze na svom prirodnom staništu nego su doneseni namjerno ili slučajno na neko novo područje. Imaju veliki utjecaj na bioraznolikost, ekosustave, gospodarstvo te zdravlje ljudi. Najčešći vektori širenja akvatičnih alohtonih organizama su brodski promet i akvakultura. Mnemiopsis leidyi, je rebraš koji je došao balastnim vodama američkih brodova u euroazijska mora u kojima se nastanio i uzrokovao velike ekološke i ekonomske štete. Prvi put je zabilježen 1980-tih godina u Crnom moru, gdje je nakon par godina uništio ribarstvo i napravio veliku novčanu štetu. Dalje se širio u Egejsko, Azovsko, Mramorno, Kaspijsko, Sredozemno i Jadransko more. Zabilježen je i u Baltičkom i Sjevernom moru. Ovaj rebraš ima niz sposobnosti koje mu omogućavaju opstanak i širenje populacije. Neke od njih su: hermafroditizam, koji dopušta svim jedinkama stvaranje plodnih ličinki; visok fekunditet; brz rast; prehrambena fleksibilnost i velika fiziološka tolerancija na temperaturu, slanost i otopljeni kisik.
Abstract (english)
Non-indigenous species are those organisms that are not found in their natural habitat but were brought intentionally or accidentally to a new area. They have a major impact on biodiversity, ecosystems, economy and human health. The most common vectors for the spread of aquatic alien species are shipping and aquaculture. Mnemiopsis leidyi is a cthenophore introduced by ballast waters from American continent in Eurasian seas, where it settled and caused great environmental and economic damage. It was first recorded in the 1980s in the Black Sea, where after a few years it destroyed fisheries and caused great monetary damage. It further spread to the Aegean, Azov, Marmara, Caspian, Mediterranean and Adriatic Seas. It has also been recorded in the Baltic and North Seas. This ctenophore has a number of abilities that enable it to survive and expand its population. Some of them are: hermaphroditism, which allows all individuals to produce fertile larvae; high fecundity; rapid growth; nutritional flexibility and high physiological tolerance to temperature, salinity and dissolved oxygen.
