摘要
Objective:To study the effect of three medicinal plants on growth,survival and immunoprotection in Mystus montanus fingerlings.Methods:The three experimental groups of fish were fed with a diet supplemented of Ocimum tenuiflorum,Zingiber officinale and Allium cepa(0.5 g each),and control group was fed without supplementation of herbal diet.After 45 d of feeding the experimental group fishes were injected with 0.5 mL of Aeromonas hydrophila and were supplemented with herbal diet.In the control group fishes were injected with 0.5 mL of physiological saline solution alone.Results:The blood samples were collected for haemotological analysis after 7 d of post infection.The results showed that the haematological parameters of haemoglobin,serum glutamic-oxaloacetic transaminase,serum glutamic pyruvic transaminase,serum glucose,red blood cell and white blood cell were found to be more in challenged fish.The survival rate of pathogen challenged fish maintained on the herbal diet is better than those in the control group which is supplemented with non-herbal diet.Conclusions:These results indicated that herbal diet is useful as a growth promoter and for disease resistance of Mystus montanus against Aeromonas hydrophila infection.
