The global aquaculture industry is one of the fastest growing food production sectors, playing an important role in fulfilling the seafood demand of a growing human population. Marine fish oils have been widely used as the main lipid source in feeds for farmed fish being a good and only reliable source of n-3 highly unsaturated fatty acids (n-3 HUFAs). Although the fish oil production has remained static, the demand for fish oil is increasing over recent years. Thus the current trend is finding the suitable alternatives to fish oils in aquafeeds, without compromising overall growth performance and final nutritional quality of farmed fish. The terrestrial alternative lipids (vegetable oils and animal fats) are the poor sources of n-3 HUFAs. The flesh of farmed fish raised on feeds containing alternative lipids may contain limited amount of n-3 HUFAs. One way to reduce to the use of declining fish oil resources in aquafeeds and to improve the nutritional quality (in terms of n-3 HUFAs)of farmed fish fed on alternative lipids, may be to use finishing feeds containing fish oil before harvesting. This review attempts to compile all principal information available regarding the efficacy of finishing feeding strategy in aquaculture.


Keywords: Fish oil, Alternative lipids, Finishing feeds, n-3 HUFAs
