Abstract

Ihtiofauna Like se u prošlosti sastojala od gotovo isključivo endemskih vrsta riba. Od kraja 19. stoljeda čovjek je unio i translocirao velik broj stranih vrsta riba u cijelu ličku regiju. Cilj ovog rada bio je utvrditi sastav ihtiofaune sliva rijeke Like, usporediti zajednice riba različitih tekudica te utvrditi stupanj bioraznolikosti, prisutnost endemskih vrsta i opde stanje zajednica. Kroz godinu dana na ukupno pet lokacija uzorkovanje ribe obavljano je elektroribolovom pri čemu je obuhvaden transekt od minimalno 50 metara vodotoka. Pomodu statističkih metoda analize podataka (ANOSIM, SIMPER, Shannon-Wiener indeks, cluster analiza, krivulja dominacije i ABC dijagram) došlo se do zaključka kako u velikoj vedini sliva prevladavaju unesene vrste poput klena i sunčanice, dok je endemska vrsta jadovska gaovica potisnuta u gornji dio toka Jadove.

Abstract (english)

In the past, the ichthyofauna of Lika consisted almost exclusively of endemic fish species. Since the end of the 19th century man has introduced and translocated a large number of foreign fish species to the entire Lika region. The goal was to determine the composition of the ichthyofauna of the Lika river basin, to compare the fish communities of different streams and to determine the degree of biodiversity, the presence of endemic species and the general condition of fish communities. Over the course of a year, at a total of five locations, fish were sampled by electrofishing, covering a transect of at least 50 meters of the watercourse. By means of statistic data analysis methods (ANOSIM, SIMPER, Shannon-Wiener index, cluster analysis, dominance curve and ABC diagram), it was concluded that introduced species such as chub and pumpkinseed sunfish predominate in the vast majority of the basin, while the endemic species Jadova minnow is repressed to the upper part of Jadova river.
