| Title |
Optimisation of trace mineral supplementation in diets for Atlantic salmon smolt with reference to holistic fish performance in terms of growth, health, welfare, and potential environmental impacts |
| Organism |
Salmo salar |
| Experiment type |
Expression profiling by array
|
| Summary |
Responsible aquaculture growth requires practices adjusted to higher knowledge based industrial standards that can secure good fish welfare, health, and low environmental impacts, alongside with the production of safe and nutritious consumer products and the economic sustainability of the business. The fish feed ingredient pallet is ever changing, from marine to plant based, and recently evolving to incorporate increasing amounts of low trophic, side stream and circular economy based raw materials, each one contributing with variable amounts and qualities of macro- and micronutrients. Meeting the micronutrient requirement of farmed fish for healthy and efficient growth under normal and challenging conditions is of paramount importance. Trace minerals are essential for critical life processes, including respiration, protein and lipid metabolism, immune responses, and cell REDOX balance. The study results bring new knowledge on Atlantic salmon physiology, growth, welfare status and utilization efficiency of trace minerals of different origin and dietary inclusion levels revealing differential effects on fillet yield, fillet technical and nutritional quality, bone strength, skin morphology, organ mineralization, midgut transcriptome, trace mineral apparent digestibility and retention efficiency, and growth.

| Overall design |
A feeding trial was based on a 2x4 factorial design with 3 replications for each dietary treatment, where Atlantic salmon smolt were fed one of 8 experimental diets supplemented with either organic or inorganic mineral premixes (copper, iron, manganese, selenium, and zinc) at 4 dietary inclusion levels. High and low levels were analysed with microarray.
