A modified functional diet and bath treathment for salmon lice control (copy) (copy)
Salmon lice is on of the major challenges to salmon farming industry in today.
The purpose of the experiment is to find a effective, rational and environmentally friendly method to control salmon lice trough a functional diet and /or bath treatments in salmon aquaculture.
The active component in the experiment is also believed to be harmless for salmon, salmon consumers and the environment. The exact effect of the active component on salmons is not yet known. Existing scientific litterature that tested "related components" did not document toxicity for salmon. "Related components" are also sold as approved human food additives.
If the results from the experiment shows that salmon lice can be controlled by a functional diet, it would have a positive effect on fish welfare due to reduced need for handling of the fish. Extra handling of farmed salmon for delousing is also a economical burden for the fish farmers. If bath treatment with the active component is the part of the experiment with positive results, the experiment still brings an effective and environmentally friendly tool for salmon lice control.
660 salmon smolts at app. 140 g in average weight are planned to be used in the foreseen experiment. The numbers of salmon smolts planned to be used are based on information from scientific literature.
By use of pit-tag`s , for individual tagging of each fish the experiment reduces the need for replicates, hereby the design of the experiment is used to reduce the number of fish needed. Reuse of infected fish from control group for bath experiment also reduces the need for number of fish used .
