Diet Composition And Analysis Of Fish Species Consumed By The Eurasian Otter In A Marine/Costal Environment, Alexandrea Otto

Department of Environmental Studies: Undergraduate Student Theses

Understanding prey preference in Eurasian otters, Lutra lutra, is important to provide greater insight into aquatic predator-prey relationships which will inform conservation efforts. Identifying the composition of an organism’s diet is one of the primary steps in understanding an organism and developing effective conservation strategies. This study expands upon basic identification of consumed items to estimate size of fish eaten by Eurasian otters to provide information on the diet of these important aquatic predators. Many studies on the Eurasian otter have considered diet from river systems, yet less is known of their diet in marine systems. The goal of my …
