Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, EarlyView.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

Beaver dam analogues increase amphibian breeding occupancy and bat activity

Restoration Ecology, EarlyView.
Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

Fluctuating densities of juvenile brown trout (Salmo trutta) and Alpine bullhead (Cottus poecilopus) over a 25-year period in the Atna River, Norway

Fauna Norvegica
Long term monitoring data from pristine or relatively unimpacted watersheds represent a valuable ecological baseline in the 21st century. Here, we present a 25-year time series of brown trout (Salmo trutta) and Alpine bullhead (Cottus poecilopus ...

Migration in anadromous brown trout

, 2016
This thesis investigates the anadromous migration of brown trout (Salmo trutta) with the overall aim to improve stock management within the region. Several field studies were conducted in different streams and coastal areas on the west coast of Sweden specifically aimed to evaluate environmental triggers for migration (Paper I), migration pathways and ...
