The work will generate new knowledge regarding whether optimal positioning of sea cages within farms may reduce lice infestation risk. The research outcomes will be useful for the development of functional and non-chemical mitigation measures. This will be advantageous as it will reduce the need for post-infection treatments against sea lice, which are challenging in terms of operation and fish welfare as well as environmentally hazardous. The project is highly relevant for the fish farming industry, management authorities and legislators as it address the following questions:
-How do infective stages of lice larvae distribute around a farm and how does this relates to variation in current?
-How does the abundance of sessile salmon lice vary among different cages and how do this relate to micro scale current pattern?
-Can optimal spatial layout and positioning of cages within farms reduce lice infestation risk?
The LiceRisk project consists of partners with different research background, including hydrodynamic, lice ecology, epidemiology and biophysical modelling. The project requires a novel and thorough integration, which will be organize in four work packages:
-WP 1 will determine the 3D current flow and the flow microstructure in the vicinity of the farm (internal and peripheral areas). Also hydrographic parameters, wind magnitude and fish distribution will be monitored.
-WP 2 will map the distribution of pelagic lice around and within farms. Plankton tows and light traps will be used the sample lice larva.
-WP 3 will assess the relationship between the abundance of sessile lice on farmed salmon among cages within farms.
-WP4 will develop a coupled biophysical model for assessment of how physical parameters influence the lice abundance around and within farms. Mitigative measures and recommendations will be defined.
