In reviews of
fish lipids, references to freshwater tropical species usually are
greatly outnumbered by those dealing with cool-temperate marine
species and commercially important freshwater species. Fish and
seafood are the richest source of the n-3 polyunsaturated fatty acids
(PUFA) in nature, and consumption of fish containing high levels of
long chain n-3 PUFA improves human health and nutrition (Ruxton
et al., 2007). The beneficial effects of n-3 fatty acids on health are
generally accredited to oils from marine species, but the lipids from
freshwater species can serve also as a valuable source of essential
fatty acids as they contain substantial concentrations of C20:5n-3
and C22:6n-3 (Steffens, 1997). The aimof this studywas to assess fat
quality, especially the content in n-3 PUFA, of the most-consumed
aquatic animal species from rice–fish farming systems.
