Overview

Validation study reveals integrated nutritional models accurately predict tissue fatty acid composition in Atlantic salmon, highlighting strategies for dietary omega-3 optimisation.

Key Points

  • Predicted fatty acid deposition aligns closely with measured values across Atlantic salmon trials, successfully tracking dietary adjustments.
  • Fillet fatty acid profiles show strong correlations exceeding R2 0.995 across cage trials, while whole-body lipid levels reach R2 0.962.
  • Integrated model coupling dynamic nutrient demand and fatty acid dilution was tested across five trials with fish weighing 138 to 5138 g.
  • Simulations support efficient dietary omega-3 allocation in commercial salmon farming, though predictions show lower accuracy for lipid levels.
