Sažetak
Croatian dace (Telestes polylepis) is a critically endangered stenoendemic fish species that inhabits the Danube basin. It is protected by Croatian law as a strictly protected species. Constant reduction of populations in its range, the quality of its habitat and the increasing anthropogenic impacts on the subterranean karst habitats where it resides for part of the year have been stated as the main reasons of its endangerment. The aims of preparing a conservation action plan were conducted and species distribution and habitat uality were assessed. The species was recorded at five sites around Velika and Mala Kapela mountains. During the investigation a large population fluctuation was detected at one site, but it is not known whether that is a natural cyclic process. In the historic range of Croatian dace, rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) were found. Presence of those species excluded the presence of the Croatian dace on historically present sites so we can conclude that the introduction of salmonid species is a major threat to the Croatian dace. In the proposed conservation action plan the general goals are mitigation measures for actual populations and eventual reintroduction of the Croatian dace in historic areas of distribution.
