Effects of different amounts of hydroalcoholic extract of eucalyptus on the blood parameters of Gras Carp (Ctenopharyngodon idella) infected with Aeromonas hydrophila

The purpose of this study the effect of eucalyptus extract on blood and immune parameters in fish infected with Aeromonas hydrophila after treatment with eucalyptus extract was Created grass carp experimentally infected with Aeromonas hydrophila density 1.5×106 ,1.5×107 ,1.5×108 ,1.2 ×109 (cfu/ml ) The peritoneal cavity of fish was the results indicate that disease in dense 1.5×108 ,1.2 ×109 (cfu/ml ) bacteria have been. Effect of eucalyptus extract concentrations 250 , 410 ,580 ,750 (ppm) baths for a short time (60 minutes) on the grass carp (average weight 25 g) were evaluated over a period of 10 days with 3 replicates. The results of the analysis of blood parameters of the fish that were tested on the basis of one way ANOVA and Duncan test showed that there was a significant difference in the amount of white blood cells, red blood cells, mean corpuscular volume, mean concentration of hemoglobin in the red blood cell, medium concentration Hemoglobin, RBC, neutrophil, Lymphocyte, Fetal blood, with control treatment (p
