Objective
The primary objective of H2Salar is to create knowledge and advance our understanding of the risks and impacts of exogenous hydrogen sulphide (H2S) to the physiology of Atlantic salmon in recirculating aquaculture systems.
The secondary objectives are:
- Document the level of H2S in different salmon RAS facilities and relate them to the health and welfare status of fish reared in the system
- Investigate the influence of different environmental variables on the production of H2S and use these interactions to develop a predictive model of H2S formation in RAS
- Identify molecular markers of H2S response and explore their role in the physiological and behavioural responses to H2S
- Examine the effects of acute and chronic H2S exposure on metabolic capacity, welfare status and production performance
- Determine the effects of acute and chronic H2S exposure on mucosal barrier functionality and robustness
