Better methods to understand fish digestion
In this project we developed analytical tools and models of the gastrointestinal system in Salmon to understand how different sources of proteins and physical pellet quality affect nutrient utilization and gut microbiota for improved fish health.

Background
Fish health and growth are affected by gastrointestinal processes. This includes feed intake regulation, digestion and absorption of nutrients, barrier function and gut microbiota.
Nutrients, ingredients and technical feed quality affects gastrointestinal processes. For the future development of feeds for an sustainable aquaculture industry it is important to understand these processes. Nofima have therefore a strategic institute funded project studying selected gastrointestinal processes affected by ingredients and feed quality. The project will develop models and analytical tools to better understand stomach function, feed intake control, digestion and absorption of nutrients in the gut. In addition to the impact on gut microbiota and barrier tissue.
Main goal
Develop analytical tools and models of the gastrointestinal system to understand how different sources of proteins and physical pellet quality affects nutrient utilization and gut microbiota for improved fish health.
Sub goals
- Develop models and analytical tool to describe how physical pellet quality affects stomach functions in fish
- Study how feeds with different protein sources affects appetite, gastrointestinal functions and microbiota
- Establish methods and tools to characterize gut microbiota, and their function in nutrient utilization in fish
