Behavioural response of carp (Cyprinus carpio, L.) pond stock upon occurrence of hunting great cormorant (Phalacrocorax carbo sinensis) flocks

Popis výsledku v původním jazyce

Electrofishing point sampling approach based on CPUE (catch per unit effort) was used to evaluate fish density (escapement) into the littoral zones of four Czech ponds as a reaction to the occurrence and hunting activities of great cormorant (Phalacrocorax carbo sinensis) flocks. The behaviour of two-year-old common carp (Cyprinus carpio) before and after cormorant arrival was compared. Significant differences (P { 0.001) in CPUE were recorded in fish density before and after cormorant arrival on all offour ponds under study - Žofinský: 0.04 +/- 0.18 and 22.38 +/- 26.87 (mean +/- SD), Starý Hospodář: 0.05 +/- 0.29 and 25.49 +/- 25.45, Žebrákov: 0.16 +/- 0.57 and 28.58 +/- 24.75 and Travičný: 0.03 +/- 0.19 and 17.18 +/- 18.20, respectively. The evaluation of fish wounding in the CPUE fish samples proved the proportion of fish injured by cormorant attacks ranging from 3.33 to 18.19% in the ponds under study.
