DO OTTERS TARGET THE SAME FISH SPECIES AND SIZES AS ANGLERS? Do otters target the same fish species and sizes as anglers? a case study from a lowland trout stream in the Czech Republic

Popis výsledku v původním jazyce

This study aimed to describe differences between otter diet and catches of anglers on a lowland trout stream with salmonid stocking. Otter diet was studied during winter, using spraint analysis. Fish dominated otter diet (85% of biomass). Gudgeon Gobio gobio was the most important otter prey (38% of biomass). Catches of otters and catches of anglers on the stream were significantly different. Otters mostly preyed upon small-growing fish species of medium or no angling value while anglers took large-growing fish species of medium and high angling value.
