English Abstract
The root of Scutellaria baicalensis are used to enhance the growth performance, non-specific immune responses and disease resistance of cobia against Photobacterium damselae subsp. piscicida and Piscicola geometra infection. P.geometra represent a new host record for cobia culture. Different concentrations of S.baicalensis root water extract were administered as supplemented fish feed was significantly increased the growth performance and disease resistance against Photobacterium in the healthy fish and fish infected by parasite. 1% concentration of S.baicalensis root were also significant increasing the humoral immune responses and cytokine related gne of cobia spleen. The upregulating of innate immune responses of cobia becomes the main reasons for the higher survival rate of cobia in the treatment group. However, the diet containing S.baicalensis extract does not have an effect on the number of parasite attachment. Bath treatment of S.baicalensis root water extract could inhibit the feeding activity of P.geometra and caused the dead of the leeches. Although histopathology analysis revealed some cellular damage occurred in the cobia gill, no acute cellular swelling was found in kidney, liver and spleen. This study demonstrated the efficiency of S.baicalensis root water extract as therapeutic agents against bacteria and parasite infection in cobia.
