摘 要：Fish farming has expanded dramatically during the last few decades,and the increasing demand for fish oil for feed production has forced the industry to search for alternative lipid sources,among them vegetable ***,focus on seafood safety has increased in recent years. Among the contaminants,is methylmercury(MeHg) of great concern,since it is highly toxic and damages the nervous *** consumption on the other hand,has positive effects on both coronary heart diseases and mental health,due to the high content of n-3 highly unsaturated fatty acids(HUFA).Thus,the interaction between MeHg and fish oil in both fish and humans is of great *** objective of the present study was to assess the effects of replacing fish oil (high dietary n-3/n-6 ratio) by soybean oil(low dietary n-3/n-6 ratio) in combination with MeHg in Atlantic salmon(Salmo salar L.) on lipid metabolism and MeHg accumulation.
