Otter, Lutra lutra, feeding pattern in the Kamenice River (Czech Republic) with newly established Atlantic salmon, Salmo salar, population

Popis výsledku v původním jazyce

Food composition of otter, Lutra lutra, was studied by the analysis of 349 spraints found during one year period (2003-2004) at the River Kamenice (Czech Republic), where Atlantic salmon, Salmo salar, fry have been stocked regularly since 1998 in a reintroduction programme for the species. Brown trout, Salmo trutta m. fario, dominated otter diet and formed 29% of all prey items and 62% of biomass of all fish eaten. The second most abundant prey (27%) was common sculpin, Cottus gobio, followed by Atlantic salmon, and grayling, Thymallus thymallus. The proportion of salmon in the diet of otters amounted to 14.5% in numerical abundance of all prey items taken and 2% in biomass of fish component of the diet. The majority (71.5%) of fish eaten by otters hada total length between 61 to 200 mm.
