Taskforce salmon lice

– spread and infection mechanisms of sea lice in sea based aquaculture and wild populations of salmonids

Photos of fieldwork in boat and at a fish farm.

Taskforce salmon lice is a R&D project organised as a PhD program at NTNU. The overall objective of the program is to establish fundamental knowledge on how sea lice infest farmed salmon and the mechanisms of how the parasites spread within and between farmed and wild populations of salmonids.

The general research strategy is to establish knowledge based on ecological, metabolic and molecular/genetic methods to characterise interactions between parasite and host (sea lice and salmonids).

The program is organised in three areas:

  • Internal infection of sea lice within and between salmon farms
  • Interactions between farmed and wild salmonids
  • Infestation mechanisms and genetic tracing

The project consists of three parts: one part funded by aquaculture companies in Mid-Norway, one funded by FHF, and one by NTNU.
