Gill disease in farmed Atlantic salmon is a significant problem. Poor gill health, often caused by infectious agents or bad water quality or a combination of these, severely compromises the animal welfare and growth. With the increasing focus on recirculation aquaculture systems (RAS) and more intensive production, new challenges related to the epithelial function of the gill are expected.
The primary objective is to establish an in vitro gill epithelial model for Atlantic salmon as a bioassay to predict harmful environmental and infective challenges and as a tool to study cellular mechanisms and transepithelial transport. Through this, we aim to reduce the number of Salmon used in experimental trials for the study of gill health. To achieve this we will use the salmon epithelial gill cell line ASG10, recently developed in our project group. It provides increased knowledge, at the cellular level, on treats against a good gill health of Atlantic Salmon
GILLMODEL is financed from The Norwegian Research Council – HAVBRUK 2, fish health – methods to replace, reduce and refine the use of fish in research (3R).
