Could a diet enriched with
n-3 highly unsaturated fatty acids be considered a promising way to enhance
the immune defences and the resistance of Penaeid prawns to
environmental stress?

Abstract:
The prawn Penaeus stylirostris (Stimpson),
when fed for 28 days with n-3 highly unsaturated fatty acid
(HUFA)-enriched feed pellets, demonstrated an enhanced resistance to
variations in environmental parameters (a decrease in temperature and
salinity over a 4-day period from 28 °C to 17 °C and from 35‰
to 10‰ respectively) and an improvement in their immune defence potential,
i.e. increased agglutination titre of plasma and increased respiratory burst
of haemocytes.
