We will run experimental feeding trials, where the outcomes of the previous objective will be combined with the state-of-the-art knowledge of the effects from fish nutrition (protein/energy ratio, ascorbic acid, a selection of essential amino acids, silicate and ethoxyquine), starvation, energy consume and compensatory growth on connective tissues and muscle softness. We will also reveal causal relations from the second generation of models from the independent nutritional and environmental variables, and the dependent variables, including gaping, softness, intracellular pH, hydroxyproline, free amino acids, collagen solubility, collagenase, hydroxylysyl pyridinoline cross link between collagen fibres, fat content, water holding capacity and drip loss in fresh and cool stored fillets. We will communicate the conclusions to the fish farming industry, in close dialog with Marine Harvest. Finally, a PhD thesis by Grigory Merkin, based on the results will be submitted
