Temporal changes in feeding ecology and life histories of Arctic charr and Brown trout in Faroese lakes

First, we compare feeding resources, fish diet and fish morphology across 3 small subarctic lakes: Leynavatn, Saksunarvatn and Toftavatn. These lakes represent contrasting combination of fish species.

By studying what fishes eat, where they are found, and how/if they compete, we can identify how they can affect the whole lake ecosystem. We compare the contemporary data to those obtained in summer 2000 (NORLAKE project), allowing an estimation of contemporary changes in salmonid species in the context of warming. We will also monitor water temperature at various depth in the lakes throughout the years.
