Reduce fish meal in diet
Between 2007 and 2008, a replicated study in Norway (Johnsen et al., 2011) found similar final weights in salmon, Salmo salar, fed low, medium and high fish meal diets. Weights across all groups increased 4-fold from an average of 1,216g to 4,625g over 275 feeding days. Three experimental feeds were fed to fish; high-fish meal diet (20% of total feed ingredients), medium-fish meal diet (15% of total feed ingredients) and low-fish meal diet (10% of total feed ingredients). Salmon were stocked in 60m circular sea cages and fed using automated feeders for a period of 275 days. Weights were recorded.
