اثر عصاره گیاه سالیکورنیا .Salicornia sp بر فعالیت آنزیم های کبدی و شاخص های آنتی اکسیدانی ماهی کفال خاکستری (۱۷۸۵ ,Mugil cephalus Linnaeus)

Salicornia sp is one of the plants with applied medicinal value. This study aimed to examine the effect of Salicornia sp plant alcoholic extract on activity of hepatic enzymes (aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP)) and antioxidant parameters (Superoxidase dismutase (SOD), Glutathione peroxidase (GPX), Malondialdehyde (MDA) catalase (CAT)) in grey mullet, Mugil cephalus for ۶۰ days. The experiment was conducted in a completely randomized design with ۲۴۰ of grey mullet (with average weight of ۸.۴۲±۰.۴۳g) in ۴ treatments and ۳ replicates (n=۲۰ in each replicate) and included: control group without using alcoholic extract, and another groups (treatment ۲,۳and ۴) the amounts of this extract were ۵۰۰, ۱۰۰۰ and ۱۵۰۰ mg/kg food. In the end of experiment, the highest antioxidant parameters of CAT and GPX and the lowest MDA antioxidant parameter and ALT,AST,ALP enzymes were observed in the diets containing ۵۰۰ and ۱۰۰۰ mg /kg alcoholic extract in all of these parameters and showed a significant difference compared with control treatment (P<۰.۰۵). So, based on the results, in order to reduce lipid oxidation and improve the liver, it is recommended to use of alcoholic extract of Salicornia sp as important feed supplements for grey mullet production.
