SLUČAJNI ULOV RIBA TOKOM UZORKOVANJA KLOPKAMA ZA RAKOVE NA DUNAVU

Klasične metode uzorkovanja ihtiofaune u velikim rekama često zanemare sitnije predstavnike faune riba koje su vezane za bentos. Tokom 2024. i 2025. godine prilikom uzorkovanja dekapodnih rakova na Dunavu zabeleženo je prisustvo 24 vrste faune riba kao slučajnog ulova. Većina zabeleženih jedinki su predstavnici sitnijih vrsta koje su vezane za bentos i izmiču klasičnim metodama uzorkovanja. Najčešći su bili predstavnici porodice Gobiidae (Neogobius fluviatilis, Neogobius kessleri i Neogobius melanostomus), kao i Perca fluviatilis. Sama metoda uzorkovanja se pokazala kao dobra za kvalitativna, ali ne i kvantitativna uzorkovanja. Zabeležene su i dve rekte i ugrožene vrste: Zingel zingel i Gymnocephalus baloni.
