"Otter (Lutra lutra) diet was studied by analysing of 180 spraints and 29 partly consumed fish remains found in winter around fishponds in South Bohemia. The proportion of fish found in spraints was 95.6% of all prey items, roach (Rutilus rutilus), topmouth gudgeon (Pseudorasbora parva) and common carp (Cyprinus carpio) being the most numerically abundant species. Carp dominated the diet by mass (47.8%), whilst roach and ?other commercial fish species? formed 21.8 and 15.3% of total biomass, respectively. Small fish (< 200 mm) predominated in the diet and only 4.0% of all fish found in spraints exceeded 300 mm TL. Large fish remains were very scarce in spraints and were best recorded from uneaten prey remains. The original length of carp corpses ranged between 283 and 530 mm TL, and the proportion of body mass consumed varied between 5.0 ? 90.1%. The length of pike remains ranged from 386 to 754 mm TL, of which 84.0% of body mass on average was consumed by otters."@en . "4" . . "Ad\u00E1mek, Zden\u011Bk" . . .
