Vertebral column adaptations in juvenile Atlantic salmon Salmo salar, L. as a response to dietary phosphorus
Deficiency in dietary phosphorus (P) is considered as a nutritional risk factor for the development of vertebral column deformities in farmed Atlantic salmon Salmo salar, L. This mono-factorial study examines how 11-week deficiency and excess of dietary P influence the structure and microstructure o...

Deficiency in dietary phosphorus (P) is considered as a nutritional risk factor for the development of vertebral column deformities in farmed Atlantic salmon Salmo salar, L. This mono-factorial study examines how 11-week deficiency and excess of dietary P influence the structure and microstructure of the vertebral bodies in juvenile, freshwater stages of Atlantic salmon.
