| Abstract: | Inconclusive results on the effect of farming on fatty acid composition of fish prevent the application of this possible variable in studies related to human health and environmental policies. The current meta-analysis used results from 39 studies to produce compelling quantitative results on differences in fatty acid components related to human health between farmed and wild fish. With seawater fish, mean effect sizes (Hedges' d) for differences in contents of EPA + DHA, total n-3 fatty acids, and the n-3:n-6 ratio were virtually zero. However, farmed freshwater fish showed a lower total n-3 fatty acid content than their wild counterparts. |
