Abstract
Sustav Plitvičkih jezera predstavlja izrazito važno ihtiološko područje s obzirom na činjenicu da se njegova ihtiocenoza podosta razlikuje od ihtiocenoza okolnih slatkovodnih sustava. Vrste koje se nalaze u samom sustavu nisu brojne, ali njihova raznolikost predstavlja bogatstvo hrvatske bioraznolikosti. Slatkovodni sustavi često su podležni različitim ljudskim utjecajima, a najveći negativni utjecaj imaju širenje i unošenje stranih vrsta. Upravo na Plitvička jezera unesena je i crvenperka. Cilj je utvrditi na koji način populacija crvenperke utječe na autohtone vrste, procijeniti invazivnost te proučiti populacijsku strukturu crvenperke u Prošćanskom jezeru. Za istraživanje sam koristio crvenperke ulovljene mrežama s pet lokaliteta na Prošćanskom jezeru, izmjerene su im standardna i ukupna duljina te masa. Na temelju dobivenih podataka proveo samstatističke analize. Poulacija crvenperke,koja ima eksponencijalnu stopu razmnožavanja, uspješno vrši kompeticijski i predatorski pritisak na nativne vrste, najviše na populacije dunavske pastrve koje su osjetljive na bilo kakve promjene unutar ekosustava u kojem obitavaju. Također, crvenperke iz Prošćanskog jezera jasno pokazuju preferenciju prema određenom tipu mikrostaništa ovisno o veličinsko-starosnoj kategoriji kojoj pripadaju
Abstract (english)
The Plitvice Lakes system is an extremely important ichthyological area due to the fact that its ichthyocenosis is quite different from the ichthyocenoses of the surrounding freshwater systems. The species found in the system itself are not numerous, but their diversity represents the richness of Croatian biodiversity. Freshwater systems are often subject to various human influences, with the introduction of alien species having the greatest negative impact. Rudd was also introduced to Plitvice Lakes. The aim is to determine how the rudd population affects native species, to assess invasiveness and to study the population structure of the rudd in Prošćansko Lake. Rudd caught with nets from five localities on Prošćansko Lake were used for the research, with their standard and total length and mass measured. A statistical analysis was made from the obtained data. Such population that has an exponential reproduction rate successfully exerts competitive and predatory pressure on native species, most notably Black Sea salmon populations that are sensitive to any changes within the ecosystem which they inhabit. Also, rudd from Prošćansko Lake clearly shows a preference for a certain type of microhabitat depending on the size and age category to which they belong.
