| چکیده | ||
| This study was aimed to assess the effect methanol extract from Padina astraulis (Hauk) on biochemical response and digestive enzyme activities in grey mullet Mugil cephalus (Linnaeus). A control diet without and a series of experimental diets were prepared with supplementation of P.astraulis extract (PE diet) at the inclusion level of 5, 10 and 15 g kg-1 diet. Three hundred sixty grey mullet with an initial mean weight of 0.82 g were randomly distributed into twelve tanks and fed twice a day (09:00 and 17:00) for 60 days. After 60 days of the feeding trial, no different was observed in survival between control and PE supplemented groups (P>0.05).Dietary PE significantly increased serum total protein, globulin levels and amylase, lipase and protease enzyme activities in treated fish (P<0.05). Moreover, there was significant decline (P<0.05) in cholesterol, glucose and triglyceride levels in those fish which received PE diet over the control. The present study elucidates the suitability of P. astraulis extract as a novel dietary supplement in grey mullet diet for improving metabolism of lipid and carbohydrate and enhancing digestive enzyme activities in grey mullet. | ||
