FishFAR Project 2022-2025
FishFar is a research project in collaboration with Hólar University, Náttúruminjasafn Íslands, University of Copenhagen and Tjóðsavnið.
The project is about Temporal changes in feeding ecology and life histories of Arctic charr and Brown trout in Faroese lakes.
The project aims to identify effects of climate change on community structure and trophic ecology of fishes in small subarctic Faroese lakes. We compare feeding resources, fish diet and fish morphology across the three 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 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.
The project will increase our spatial and temporal understanding of biodiversity of freshwater fishes in small subarctic lakes in the Faroes. This is of critical importance for successful conservation of biodiversity under the current climate and biodiversity crises.
Fieldwork for this project was conducted 5.8. - 11.8.2022. The work was done from both boat and on land.
Invertebrate samples were taken both in the open water and at the shore line at each of the three lakes (Toftavatn, Saksunarvatn, and Leynavatn). In addition, multi-mesh gill nets were layed overnight for a duration of ca. 12 h. However, at Toftavatn and Saksunarvatn it was necessary to lay them for some additional time in order to get enough fish.
The fish were photographed, measured, and dissected on site. In total around 4000 measurements and samples were taken.
