It is the main reason why in recent years there has been no or moderate growth in the biomass of farmed fish, and an obstacle to the growth that both the industry itself and the government want. Different strategies are used today, and several methods have also been developed in recent times. Often several are used in combination. Both anti-parasitic drugs, physical obstacles (lice skirts), non-medicinal methods such as mechanical de-lice removal, cleaning fish and laser are used. Several of these treatments put great strain on the fish in the form of physical strain and high stress levels, with reduced fish health and welfare as a result.
Prophylaxia AS has in close collaboration with the French research institution Irsea identified and isolated a natural signaling substance that can help solve the major challenges posed by salmon lice. The signaling substance SNAP (Salmon Nest Appeasing Pheromone) is a salmon pheromone that triggers the fish's ability to adapt and reduces the negative consequences of stress. This means that salmon exposed to SNAP are not perceived as suitable hosts for lice.
Main objective:
To develop distribution technology for optimal exposure of the fish in the cages with the signal substance SNAP, to prevent the spread and establishment of salmon lice on salmon and trout.
Sub-goals:
1. To carry out experiments to verify whether gene expression can be used as a method to verify that the fish are exposed to SNAP
2. To prepare requirements specification of distribution technology.
3. To prepare experimental designs and models for carrying out full-scale experiments.
4. Building a pilot – preparation, assembly and functional testing.
5. To carry out full-scale model trials and testing - technology assessment.
6. To carry out redesign and optimization.
