The three most important desalination methods (thermal, mechanical and fresh water), used alone or in combination, have not been systematically studied and compared so that the use of these strategies can probably be optimised. The empirical data to be collected in this project will integrate information from research and commercial scale, and will generate ""best practice"" recommendations for maximum efficiency and minimum welfare effects for de-lice methods.
Overall objective:
To compare the effects of single and combined treatments to understand under which conditions they work best, and how they affect the welfare of the salmon.
Secondary objectives:
• To investigate this further on a commercial scale.
• To explore epigenetic resistance in lice to enable optimal management plans.
Sub-objectives:
1. To determine the individual and combined effectiveness of thermal, mechanical and freshwater de-littering strategies for the removal of sessile and mobile lice.
2. To investigate the effect of these strategies on salmon welfare (including individual-based indicators).
3. Determine which factors can positively influence effectiveness and welfare.
4. To determine the de-lice effect and the welfare effect of commercial-scale de-lice strategies.
5. To identify epigenetic C5m DNA methylation markers for adaptability to high temperature and low salinity and describe its heritability.
6. To investigate whether epigenetic changes in response to temperature and low salinity coincide.
7. To investigate the change in the frequency of epigenetic markers associated with deworming.
8. To make "best practice" recommendations for de-lice based on results from this project and available information.
