摘要：

Otter faeces were collected at monthly intervals from around two lakes near the River Dee in Aberdeenshire in 1975 and 1976. They were analysed to show the frequency of occurrence of identifiable undigested items and also the relative bulk of these different items. Statistical differences were recorded in frequency of occurrence. The main food was eel in both years with small perch also important in January to June and amphibia in the spring. A reduction in the frequency of eel in the faeces was associated with fewer observations of otters. Copyright © 1979, Wiley Blackwell. All rights reserved
