  1. Use an alternative protein source: krill

    A replicated study in Norway (Hansen et al., 2010) found that salmon, Salmo salar, fed partially de-shelled krill meal had similar growth rates to those fed a whole krill meal diet. During the first 56 days, growth rates of 0.86% and 0.76% were recorded, respectively. Average final weights of salmon were 1060g, 1100g and 956g in fish fed diets containing fish meal, de-shelled krill and whole krill meal, respectively. Three diets were fed to 225 salmon for 100 days: a control diet based on high-quality fish meal or one of two experimental diets where the fish meal was substituted with either partially de-shelled or whole krill meal. Growth rates and final weights were recorded.
