A replicated study in Norway (Karalazos et al., 2011) found that salmon, Salmo salar, fed diets containing rapeseed oil had higher growth rates and average final body weights compared to those fed diets containing fish oil. Growth rates were 0.94 and 0.87, respectively. Average final weights were 3.64kg and 3.34kg, respectively. Protein content did not affect growth parameters. Six experimental diets were fed to salmon over a 10 week period. Three contained high, medium and low protein content and 100% fish oil. Three contained high, medium and low protein content and 100% rapeseed oil. The protein/lipid contents were high: 350g per kg/350g per kg, medium: 330g per kg/360g per kg and low: 290g per kg/380g per kg. Growth rates and final body weights were measured.
