Sea lice challenge model development and dietary management optimisation against sea lice

Atlantic salmon will be infected with controlled levels of sea lice and fed diets containing authorized food additives to test their effects against sea lice. Expected distress for the fish is minimal. Dietary management is part of an integrated pest management strategy to improve fish welfare. 2465 post smolt salt water adapted Atlantic salmon will be used in a series of experiments. Fish handling and sea lice infection challenge protocols will follow Skretting ARC standard operating procedures. Fish will be euthanized with MS-222 (TMS) and terminally sampled. These experiments will build on earlier experiments (Id 8286) by furthering scientific and practical knowledge about sea lice infestation and response to dietary and chemical management.
