The experiment was conducted in a completely randomized design with 240 grey mullet (with average weight of 8.42±0.43g and average length of 6.45± 0.40 cm) in 4 treatments and 3 replicates (n=10 in each replicate) and included: treatment 1 (control), treatment 2 (0.5g MET/kg diet), treatment 3 (1g MET/kg diet) and treatment 4 (1.5g MET/kg diet). At the end of experiment, the lowest cholestrol and triglyceride and and highest albumin of blood serum were observed in treatment 3 and 4 (P< 0.05). The lowest glucose androtein and glubolin were observed in treatment 4 and there is a significant difference between all of treatments (P< 0.05). The highest the activity of amylase enzyme and the lowest the activity of asoartat aminotransferase and alanin aminotransferase enzymes were observed in treatment 3 and 4 but there was no significant difference among them (P>0.05). So, finaly the present results showed that use of the diet containing 1.5 g g the methanol extract o of gokshura /kg had positive effects on the activity of liver and digestive enzymes and blood biochemical parameters of grey mullet.
