The North American river otter (Lontra canadensis) is a predator adapted to hunting in water, feeding on aquatic and semi-aquatic animals. The vulnerability and seasonal availability of prey animals primarily determines the food habits and prey preference of the river otter (Erlinge 1968; Melquist and Hornocker 1983). There are
Diet is an important ecological component for apex predators like the North American river otter (Lontra canadensis; hereafter river otter).
River otters are known to prey on an array of species such as insects, crustaceans, freshwater, anadromous, and marine fishes, amphibians, reptiles, waterbirds, and small mammals (Melquist et al., 2003). The diet of river otters also can vary seasonally and is assumed to reflect
15 Δεκ 2023 · Using scat analysis, we studied the diet of a population of river otters (Lontra canadensis) that were re-introduced into the Verde River valley in north-central Arizona.
The goal of this study was to investigate aspects of river otter ecology in Pennsylvania. The objectives were to: 1. Provide genetic profile of river otters in PA. 2. Provide an analysis of river otter diet in PA. 3. Identify the ecto and endo parasites of otters in PA.

A formal nutrition program is recommended to meet the behavioral and nutritional needs of all animals. Diet formulation criteria should address the otters’ nutritional needs, feeding ecology, as well as individual and natural histories to ensure that species-specific feeding patterns and behaviors are stimulated.
