Study of blood biochemical and liver antioxidant parameters changes in grey mullet, Mugil cephalus fed with red seaweed Jania adhaerens J.V. Lamouroux extract

Abstract

The objective of the study was to examine the effects of red seaweed Jania adhaerens J.V. Lamouroux extract (JE) on blood biochemical parameters and antioxidant enzyme activity of grey mullet, Mugil cephalus, after 60 days. Four experimental diets were prepared: JE0 as a control group; JE5, JE10 and JE 15, which included 0, 5, 10 and 15 mg JE kg-1 diet respectively. One hundred twenty grey mullet weighting 14.95± 2.01 g (mean± SE) was randomly divided into four groups corresponding to the different feeding regimes.After 60 days feeding with above diets, No significant differences were evident in albumin and catalase (CAT) between the control group and treatments (P>0.05). The lowest levels of glucose (GLU), cholesterol (CHO), alkaline phosphatase (ALP), alanine aminotransferase (ALT) and the highest glutathione (GSH (activity were shown in JE15. Treatments containing different levels of JE showed significantly different in superoxide dismutase (SOD), MDA, GSH, total protein and globulin compared with control treatment (P<0.05). Overall, the results of the experiment revealed that grey mullet fed with JE10 and JE15 diets showed improvement of the activity of antioxidant enzymes and blood biochemical parameters and use of diet containing 15 mg/kg J.adhaerens extract could suggest for grey mullet.
