Summary: This study aims to investigate the effect of the replacement of dietary fish oil with oil from Camelina sativa on the immune response of Atlantic cod, as measured by the gene expression in spleen. In conclusion, replacement of up to 80% of fish oil with camelina oil in Atlantic cod diets does not have a strong effect on basal spleen gene expression. Atlantic cod fed on camelina oil-containing diets are capable of mounting a strong anti-viral immune response, which is comparable to that in cod fed with a fish oil diet. Link:
