Better resource utilization and increased economic value from fish that die in aquaculture
Despite efforts to maintain good health in fish farming, the mortality rate is significant. The dead fish are a potential rich source for nutrients and energy. However, their use in feed is currently limited by strict regulations. At the same time, there is a strong focus on sustainability and circular economy, making the return of nutrients sourced from dead fish in the feed chain essential. However, the material may contain biological and chemical risk factors such as aquatic fungi and mycotoxins, so that a careful evaluation of potential risk factors is needed before the material may be used in feed production. Furthermore, its nutritional value has to be maintained during feed processing.
The aim of the project is thus to develop methods and provide documentation to enable an increased and safe use of dead fish in feed production.
