Abstract
    Within the framework of a biosurveillance of the marine species on the Tunisian coasts, we studied the salema (Surpa salpa), a fish that is widely consumed in this region. The aim was to determine the seasonal variation in the diet composition of salema and to correlate it with the antioxidant activity in tissues of this fish. The salema living around the Island of Kerkennah is proved to be a primarily herbivorous fish during all seasons. We observed an increased antioxidant response in some of its organs in comparison with those found in our control fish, the annular seabream, with a "season-depending" cumulative effect, appearing in the organs starting with the liver followed by the brain and finally the flesh. Moreover, it increases according to the size of the animal and thus to the amount of food it consumes. The seasonal variation in the epiphytes is parallel to the hallucinogen effects that the consumption of these fish has on humans. A significant correlation (P < 0.01) is also observed between the total toxic algae dinoflagellates and the antioxidant response: catalase (CAT) and glutathione peroxidase (GPx) in liver, brain and flesh for all seasons and all sizes together.
