Abstract

Cilj rada bio je odrediti Fultonov faktor kondicije i ulov po jedinici napora (CPUE) za štuku (Esox lucius) na području Lonjskog polja. Istraživanje je provedeno na tri lokacije, rijeci Lonji, Česmi i Sunji u razdoblju od rujna 2018. do svibnja .2019 g. U ribolovu je sudjelovalo 7 ribolovaca, a ulovljeno je ukupno 32 štuke. Najveći prosječni faktor kondicije izračunat je za štuke u rijeci Lonji (0,85 ± 0,17). Umnožak broja ribolovaca i broja sati provedenih u ribolovu označavao je ribolovni napor, a prosječni CPUE izračunat je na temelju broja riba u jednom satu i na temelju mase riba po ribolovcu u jednom satu. CPUE na temelju broja ulovljenih riba za rijeku Lonju iznosio je 0,035, za rijeku Česmu 0,02 te 0,04 za rijeku Sunju. CPUE na temelju mase ulovljenih riba iznosio je 57,86 g ribolovac/sat za rijeku Lonju, 61,46 g ribolovac/sat za lokaciju rijeke Česme te 47,05 g ribolovac/sat za rijeku Sunju.

Abstract (english)

The aim of the study was to determinate the condition factor and Catch Per Unit Effort (CPUE) for pike (Esox lucius) in the area of Lonjsko polje. The study was based on three location, river Lonja, Česma and Sunja in the period from September 2018 -May 2019. Seven anglers participated in angling and 32 pike were caught.. The highest value of condition factor was calculated for pike from the river Lonja0,85 ± 0,17. A multiplicity of fishermen indicated effort and average CPUE was calculated based on the number of fish in one hour and based on the mass of fish per fisherman in one hour. The CPUE based on the catch of fish from the river Lonja amounts to 0,035, for the river Česma 0,02 and 0,04 for the river Sunja. The CPUE based on the mass of fish amounts to 57,86 g angler/hour for the river Lonja, 61,46 g angler/hour for the river Česma and 47,05 g angler/hour for the river Sunja.
