Effective and environmentally friendly mechanical treatment for salmon delousing

Periodic Reporting for period 1 - DeBug (Effective and environmentally friendly mechanical treatment for salmon delousing)

Reporting period: 2019-12-01 to 2020-11-30

Sea lice infestation is one of the greatest marine parasite challenge that the farming industry face, and the sea lice problem is a biological limiting factor for further development of the salmon farming industry.

The overall vision of the DeBug project is to upscale, pilot and commercialise our unique method for decreasing sea lice infestation in marine salmon farming.

The DeBug solutions shall ensure the following 3 key principles are maintained:
1. Unparalleled delousing efficiency/removal results
2. Exceptionally low stress and mortality rates for the fish
3. Functional Design and Operational flexibility

With global food shortage, being able to grow the biomass salmon production, finding better solutions to handle lice infestation is essential for the society. Being able to ensure fish welfare in the process is a requirement.
With the ongoing global pandemic, the project has strived to maintain progress and at the same time keeping the project members safe by avoiding risk of exposure/infestation. To date all members of the team has managed to continue the work (e.g. working from home) and remaining healthy. The WP1 is nearing completion, with very promising results from the prototype testing at NOFIMA.

Based on the encouraging results from the prototype testing, the initial work of WP2 has been initiated, focusing on maintaining schedule for the large-scale pilot testing onboard MV SealiceHunter. Discussions with a Norwegian farming operator is in final stages of negotiations regarding pilot testing on larger volumes of live fish.

Status of the development divided onto two separate phases are as follows:
Work-Pack 1(WP1):
- Design and build a small-scale pre-treatment unit – 100% completed
- Perform testing at Nofima – 90% completed (pending a NOFIMA final report on fish well-fare)
Work-Pack 2(WP2):
- Design, build and test a large-scale DeBug system onboard the SealiceHunter – 30% completed
Based on progress and results to date, by having achieved very promising results from phase 1 - prototype testing, the expectations are that the project will document and prove unprecedented delousing results with superior fish welfare compared to all other solutions available in the market.

This will form the building blocks for further company growth and employment, targeting to fully commercialising the technology by 2024. The success of the project will support further growth in the EU salmon biomass production and aquaculture in general.
