Comparative information on blood metabolic responses would be necessary to investigate variably prebiotic effects in
several fish. Blood chemical parameters were measured to help interpret the nutritional and health status of Nile tilapia
that were fed dietary inulin and JA. Most of the blood chemical parameters showed the same trends for fish fed diets
supplemented with inulin and JA, which suggests that JA could be used directly as a food ingredient, at least in Nile tilapia.
However, limited information is available about the effect of dietary inulin on blood chemistry (Reza et al., 2009), and more
studies are needed.
