The fatty acid composition of total lipids from edible portions of pondreared prawn, catfish, and crayfish were compared with those of their wild counterparts. It was found that the lipids of the cultured animals had higher levels of ω6 fatty acids and lower ω3 fatty acid levels and ω3/ω6 ratios compared with their wild counterparts. The pelleted catfish diet was rich in ω6 fatty acids. It was concluded that the lipids of pond-reared fish and shellfish may not have the high levels of ω3 fatty acids found in wild seafood, and that the feasibility of increasing the ω3 fatty acid content by dietary manipulation, needs to be investigated.
