Offentlig prosjektsammendrag

Most of the current non-medicinal sea lice treatments involve confinement, crowding, and movement of fish. This causes significant levels of stress as well as mechanically induced wounds. Stressed fish will have reduced feed intake, and it has been shown that they are more susceptible to diseases. A robust fish capable of coping with handling induced stress is the main factor suggested to manage this issue (combined with reduced de-licing activities). Certain plant ingredients have been identified to mitigate the stress response in fish. Adding these ingredients might reduce the subsequent effects of handling stress (low appetite, reduced fillet quality etc), and improve fish health and welfare. This will be tested in an experimental feeding trial with Atlantic salmon mimicking commercial farming routines as best as possible. The project will identify plant ingredients that can reduce stress after handling and thus boost robustness, fish health, and fillet quality.
