Description:
Medicinal plants have been used in oriental medicine for centuries. Echinacea purpurea (Asteraceae), also
known as the purple coneflower, is an herbal medicine with positive effects on various immune parameters that
has been used customarily as a treatment for the common cold, coughs, bronchitis, upper respiratory infections,
and some inflammatory conditions. The aim of this study was to investigate the effect of Echinacea purpurea
(EP) extract on a non-specific immunity of Mugil cephalus. Three hundred and sixty Gray mullet larvae with
average weight of 0.75 ± 0.02 g and an average length of 4.40 ±0.81cm collected from Ramin port where is
located at 5 km far from the Chabahar and finally transferred to lab of trial in Offshore Research Center. This
research was designed based on 4 treatment, Each with 3 replicates. The major factors examined containing
growth factors mainly consists of average weight, average daily gain, protein efficiency rate, protein productive
rate, hematological and biochemical factors including globin, albumin, total protein, lysozyme, ultimately,
immunological factors, and respiratory burst and phagocytosis percent. In general, the results of this study
showed that the addition of 100 and 200 mg of EP extract per kg of diet led to a significant increase in growth
parameters (final weight, food intake, daily growth rate and efficiency of protein), hematology (RBC, WBC, Hb,
Hct) and biochemical factors (total protein, albumin, globulin) in gray mullet were compared to control. The
highest lysozyme activity, immunoglobulin, phagocytosis and respiratory burst was observed in treatment
containing 200 mg EP extract per kg food. Treatment containing 200 mg EP extract per kg food showed a
minimal mortality after challenge with bacteria photobacterium damselae compared to the control treatment.
Finally, the present results suggest that diet containing 200 200 mg EP extract per kg food could improve
growth, hematology, immunity and resistance against photobacteriosis of grey mullet.
