Abstract
Ovim radom se istražuje utjecaj hidrocentrale na reproduktivne značajke klena (Squalius cephalus) u rijeci Sunji. Glavni cilj ovog istraživanja je utvrditi vrijeme mrijesta i ostale reproduktivne značajke klena iznad hidrocentrale i u nastavku riječnog toka nizvodno u rijeci Sunji. Također, utvrdit će se abundanca klena u ukupnoj ihtiocenozi, njegova dužinska i spolna struktura, kondicija i dužinsko-maseni odnosi. Uzorkovanje je provedeno na tri lokacije rijeke Sunje: Staza (bez utjecaja hidrocentrale), Mlin (akumulacija hidrocentrale), Klipić (ispod hidrocentrale). Analizom su utvrđene razlike u sastavu ihtiocenoze i abundance klena ovisno o lokaciji. Razlike gonadosomatskog indeksa klena uzrokovani su različitim ekološkim uvjetima te pokazuju da se mrijest ne odvija u isto vrijeme na svim lokacijama. Hidrocentrala ima ključni utjecaj na formiranje okolišnih karakteristika u određenom dijelu toka i tako izravno utječe na reproduktivne značajke klena.
Abstract (english)
This work investigates the influence of the hydropower plant on the reproductive characteristics of the chub (Squalius cephalus) in the Sunja River. The main aim of this research is to determine the spawning time and other reproductive characteristics of the chub above the hydropower plant and in the continuation of the river flow downstream in the Sunja River. The abundance of chub in the total ichthyocenosis, along with its length and sex structure, condition, and length-weight relationship, will also be determined. Sampling was carried out at three locations of the Sunja River: Staza (without the influence of the hydropower plant), Mlin (accumulation of the hydropower plant), Klipić (below the hydropower plant). The analysis revealed differences in the composition of the ichthyocenosis and chub abundance depending on the location. Differences in gonadosomatic index are caused by different environmental conditions and indicate that chub spawning does not occur at the same time in all locations. The hydropower plant has a key influence on the formation of environmental characteristics in a certain part of the stream and thus directly affects the reproductive characteristics of the chub.
