  1. Use an alternative oil source: plant-based

    Between 2002 and 2004, a replicated study in Norway (Jordal et al., 2007) found that liver lipid and plasma lipoprotein levels were affected when salmon, Salmo salar, were fed vegetable oil-based diets as a complete replacement for fish oil. Salmon weights were similar and increased from 890g to 2.3kg and 2.7kg in the fish oil and vegetable oil groups, respectively. Lipid liver stores were higher in fish fed the vegetable oil diet after 14 and 22 months of feeding. In contrast, plasma lipid levels were lower. Over 22 months, 2,000 salmon juveniles were fed diets containing either 100% fish oil or 100 % vegetable oil (comprising 55 % rapeseed oil, 30 % palm oil and 15 % linseed oil). Fish meal was used as a protein source. Fish were weighed at 0, 6, 9, 14 and 16 months. Liver and plasma were analysed for lipid and lipoprotein content.
