  1. Use an alternative protein source: animal

    A controlled, replicated study in British Columbia, Canada (Wilson et al., 2007) found no differences in oxygen consumption or swimming speed of Atlantic salmon that were fed diets with different dietary lipid sources. There were similar swimming speeds (0.69- 0.76 m s-1) and oxygen consumptions (MO2 max 7.31± 0.24 mg O2 kg−1 min−1) for the five dietary treatments. Five experimental diets containing 45% protein and 26% lipid) were each fed to 150 Atlantic salmon (across three tanks) for 24 weeks. The control diet contained 100% anchovy oil and in three diets 75% of the anchovy oil was replaced by poultry fat, cold pressed flaxseed oil, or crude super de-gummed canola oil. The fifth diet contained a 1:1 blend of anchovy oil and poultry fat and the protein component was a 1:1 blend of fishmeal and poultry by-product meal. After 24 weeks on the experimental diets, ten fish of similar weight from each trial were tested by measuring oxygen consumption rates, prolonged swimming performance, and recovery from exhaustive exercise in a closed circuit respirometer over a seven week period.
