The antioxidant defence and immune response of rainbow
trout (Oncorhynchus mykiss) that had received plant oils, rich
in either n-3 polyunsaturated fatty acids (PUFA; linseed oil) or
n-6 PUFA (safflower oil) was evaluated upon antigen expo sure. The fish employed in this study had been offered the diets
for 18 months from the first feeding. Rainbow trout from
each group were injected intraperitoneally with formalin killed bacteria (Aeromonas hydrophila) or were sham-injected
and observations were made 24 h later. Though the fish fed
safflower oil seemed to be under relatively greater oxidative
stress, the antioxidant defences (superoxide dismutase, cata lase, glutathione peroxidase) were as effective as in those fed
linseed oil. The humoral (alternate complement activity
and lysozyme activity) and cellular (phagocytic activity and
lymphocyte proliferation) immune responses were not
significantly affected by the oil offered. With the exception of
reactive oxygen production that was significantly greater in the
linseed oil fed fish, both groups did not differ greatly in their
immune responses after antigen exposure. Thus, fish fed
safflower oil that was deficient in n-3 PUFA was able to sustain
most of the critical responses similar to those fed linseed oil
suggesting that plant oils of both fatty acid categories were
effective for this fresh water fish.
