Abstract

Sportski ribolov u Republici Hrvatskoj definira se kao lov riba radi rekreacije i natjecanja. Ulov po jedinici ribolovnog napora (CPUE) je neizravna mjera abundance istraživanih vrsta, a predstavlja parametar koji je u pozitivnom odnosu sa brojem i masom riba. Cilj rada bio je analizirati podatke ulova u sportskom ribolovu ovlaštenika ribolovnog prava na ribolovnom području rijeke Save tijekom desetogodišnjeg razdoblja, izračunati CPUE (kg po ribiču godišnje) te usporediti i interpretirati rezultati ulova važnijih vrsta riba u razdoblju od 2010. – 2019. Prosječan broj ribiča na rijeci Savi u razdoblju od 2010. do 2019. godine iznosio je 12 766±952 ribiča tj. od najnižeg 10 876 za 2015.g. do 13 863 ribiča za 2019.g. Ukupan ulov se kretao od 197 983,9 do 274 570,0 kg godišnje. Najzastupljenije vrste u ukupnom ulovu u navedenom razdoblju su šaran (Cyprinus carpio), babuška (Carassius gibelio), amur (Ctenopharyngodon idella), štuka (Esox lucius) i deverika (Abramis brama). Ulov po jedinici napora (CPUE) kretao se između 14,5 kg/ribiču (2018.) i 24,29 kg/ribiču (2015.) godišnje, dok je prosječna vrijednost CPUE-a u istraživanom razdoblju iznosila 19,37±2,77 kg/ribiču godišnje.

Abstract (english)

Sport fishing in the Croatia is defined as fishing for recreation and competition. Catch per unit of fishing effort (CPUE) is an indirect measure of the abundance of researched species and is a parameter that is positively related to the number and weight of fish. The aim of this study was to analyze the catch data in sport fishing in the Sava River during a ten-year period, also to calculate CPUE (kg per fisherman per year) and compare and interpret the results of catches of important fish species in a period from 2010 to 2019. Number of anglers on the Sava River in the period from 2010 to 2019 averaged from 10,876 to 13,863 anglers for each year, and the total catch ranged from 197983,9 to 274570,0 kg per year. The most common species in the total catch were common carp (Cyprinus carpio), Prussian carp (Carassius gibelio), grass carp (Ctenopharyngodon idella), northern pike (Esox lucius) and freshwater bream (Abramis brama). The catch per unit of effort (CPUE) ranged between 14.5 (2018) and 24.29 kg / fisherman per year (2015), and the average value of CPUE was 19.37 ± 2.77 kg / fisherman per year.
