Use an alternative protein source: bacteria Sustainable Aquaculture

A controlled, replicated study in Norway (Aas et al., 2006) found that salmon, Salmo salar, fed diets containing 18% and 36% bacterial protein had faster growth rates than those fed a 100% fish meal control diet or experimental diet containing 4.5% bacterial protein. Growth rates were 1.59, 1.56, 1.38 and 1.37, respectively). Salmon were fed diets in which bacterial protein made up 4.5%, 9%, 18% or 36% of the ingredients, replacing fish meal or a control diet made up of 100% fish meal. They were fed using automated feeders for 48 days. Weights were recorded.
