Benchmark's Fish Vet Group (FVG), Marine Harvest Norway, the Norwegian University of Life Sciences (NMBU) will work together on a three-year project that aims to better understand the risk factors of gill disease in Norwegian farmed salmon.

The project is primarily funded by the Norwegian Seafood Research Fund (FHF), with contributions from Marine Harvest and FVG.

Compromised gill health has emerged to be a major factor in the farming of salmonids in Norway, leading to economic losses and reduced animal welfare in both the marine and freshwater phases of production.

The project consists of three work packages and is aimed at identifying risk factors for gill disease, with a focus on the effect of net management strategies on gill health.

The potential effects of phyto- and zooplankton, different net types and net maintenance, as well as thermal and mechanical sea lice treatments will be evaluated in order to identify management strategies that can prevent, reduce and minimise impact of gill disease.

In addition, the researchers aim to identify useful indicators of gill health to help management decision-making at farm level.

The project has already started and is expected to be finalised in the summer of 2021.

More information regarding the project is available on FHF’s website.
