Abstract

      Juvenile gilthead sea bream (Sparus aurata L.) were fed commercial diets with 150, 500 and 1000 mg of vitamin C per kg of basal diet. One group was kept in starvation. The experiment lasted 98 days.

     The total and L-ascorbic acid levels were found to be highest in the brain, kidney, liver, gills and white muscle at the beginning of the experiment. Ascorbic acid concentrations in brain, gills, liver and white muscle showed no significant differences due to the different dietary treatments, whereas the diets containing supplemental ascorbic acid of 100, 500 and 1000 mg vit. C kg-1 significantly affected total ascorbic acid level in the kidney. Groups offish grown on different diets and starved showed no statistically significant differences in L-ascorbic acid levels in the gills and brain, whereas the significantly highest concentra­tions were recorded in the liver, white muscle and kidney of starved juveniles.

      Sampling time and different diets did not affect the concentrations of the total and L-ascorbic acid in the gills and white muscle, or the total ascorbic acid levels in the kidney which does not hold for the brain and liver.
