Effect of Diet Supplemented with a Fermented Vegetable Product on Lipid Peroxidation in Liver of Japanese Flounder, Paralichthys olivaceus

抄録

We investigated the effects of Manda®, a fermented vegetable product (FVP), on the growth and lipid peroxidation of Japanese flounder (Paralichthys olivaceus) . Fish were fed on diets containing FVP (3, 6, and 15 mg/kg body weight/day) for 8 weeks. The final body weights of these fish were slightly influenced by the dietary treatments, whereas the level of lipid peroxidation in the livers was significantly (p<0.01) lower than that in control fish (without FVP) . These results suggested that the feeding of the FVP to fish reduces oxidative stress, and may be useful for the rearing of cultured fish.
