Abstract

Cilj istraživanja je bio, uz pomoć podataka o ulovu ribiča, analizirati slatkovodne riblje zajednice, izračunati CPUE te usporediti i interpretirati rezultate ulova važnijih vrsta riba u sportskom ribolovu na ribolovnom području "Kupa" kroz razdoblje od 2009. do 2017. godine. Prosječan broj ribiča na rijeci Kupi u razdoblju od 2008. do 2017. godine je iznosio prosječno 2041 do 2719 ribiča godišnje; a ukupan ulov se kretao od 64591,40 do 19994,10 kg godišnje. Najzastupljenije vrste u ukupnom ulovu u navedenom razdoblju su šaran (Cyprinus carpio), štuka (Esox lucius), som (Silurus glanis) i amur (Ctenopharyngodon idella). Prosječna vrijednost ulova po jedinici napora (CPUE) u istraživanom razdoblju iznosila je 12,27 kg/ ribiču godišnje i imala je porast u 2014. godini (28,19). Tijekom posljednje dvije godine istraživanja, vrijednosti su pale nešto ispod prosjeka te su iznosile oko 9,8 kg / ribiču godišnje.

Abstract (english)

The aim of the study was to analyze freshwater fishery communities, calculate CPUE and compare and interpret the results of catches of important fish species in recreational fishing in the "Kupa" fishing area during the period 2009.-2017 by using fishery catch data. The average number of fishermen on the Kupa River from 2008. to 2017. averaged 2041 to 2719 fishermen annually; and the total catch ranged from 64591,40 to 19994,10 kg per year. The most common species in the total catch during the period indicated are carp (Cyprinus carpio), pike (Esox lucius), catfish (Silurus glanis) and grass carp (Ctenopharyngodon idella). Average value of catch per unit effort (CPUE) in the researched period was 12.27 kg / fisherman per year and had an increase in 2014 (28.19). Over the last two years of the research, values had dropping to slightly below average and amounted around 9.8 kg / fisherman per year.
