Modulated nutritional composition for Atlantic salmon (Salmo salar) to support against winter sore (copy)
A large proportion of fish in farming have wounds, and it is important to acquire knowledge about the connection between nutrition and infectious diseases, so that feed composition is optimized. Previous trials evaluation wound healing response in Atlantic salmon have shown that optimized nutritional composition can improve wound healing up to 40%. More precise knowledge about the interaction of key nutrients to optimize the modulated nutritional composition in the feed to understand the support the feed have on reducing susceptibility to bacterial infection in Atlantic salmon is necessary. This could contribute to a more effective prevention against infectious diseases.
1. Purpose: In this study, modulated nutritional composition of the feed will be evaluated against winters sores in Atlantic salmon. Salmon are fed three different modulated nutritional composition feed including a base diet.
2. Distress: Development of wounds is believed to be a cause of pain. Mortality can be expected. Fish with wounds will be scored and taken out of the experiment.
3. Expected benefit: it is important to increase knowledge in modulation of nutritional composition of the feed to support against winter sores to minimize the handling.
4. Number of experimental animals: 1080 salmon smolts (Salmo salar L.)
5. 3R: Fish are analyzed at defined times. There are no other methods that can show whether feed actually has a practical effect on increased protection against ulceration of M. viscosa, and the number of fish in the experiment is based on the number of fish for sampling and expected mortality.
