چکیده
abstract: influence of both dietary and bath administration of eucalyptus globules labill was evaluated on some immunological variables of common carp (cyprinus carpio) under temperature less than optimum in order to determine stimulatory effect of the essential oils. fish weighing 30-35 g were bathed or fed with different doses of 30, 60 and 120 |m|l/l or mg/kg feed for a period of 8 days. serum lysozyme activity, bactericidal activity, total white blood cells, total protein, globulin and albumin were measured on days 1, 2, 8, 15 and 23 after the essential oils administration. on day 23 post administration the remaining fish from each group were intraperitonealy injected with killed aeromonas hydrophila (6×108cells/ml) and antibody titer was measured 3 weeks later. the obtained results showed that eucalyptus globules had a limited immunostimulatory effect on these immunological variables although antibody titers and total white blood cells in some test groups were significantly (p

Common Carp, Cyprinus carpio
The common carp (Cyprinus carpio) belongs to the family Cyprinidae. In nature, carp live in the middle or lower reaches of a river with slow currents, or in marshes. Their habitats are usually weedy areas with a muddy bottom. Carp fry feed on zooplankton such as rotifers and copepods, but as they grow up they become benthic feeders, feeding on animals and other organic material. The cyprinids h...

متن کاملEffects of Aflatoxin-Contaminated Feed on Immunological Parameters of Common Carp (Cyprinus Carpio)
Background: Aflatoxin contamination is a common natural phenomenon that is difficult to avoid or control and it can occur during pre and post-harvest periods under high humidity and temperature conditions, and are potentially dangerous to fish. In the present study, a feeding trial evaluated the effects of diets contaminated with aflatoxin on certain immunological parameters of common carp. Me...
متن کاملEvaluation of some hematological and sero-immunological parameters of common carp (Cyprinus carpio) during of overwintering
Due to the sharp decrease or lack of feeding of carp during winter and the effects of malnutrition on fish health, the aim of the study was to determine the effect of overwintering on hematological and some sero-immunological parameters of cultivated common carp (Cyprinus carpio). The samples were gathered two times (March and May) from one the earth pond in Behshar. Every time, 30 fish were ca...
متن کاملEvaluation of Eucalyptus (Eucalyptus globulus) essential oil on growth performance, hemato-immunological parameters and resistance against Aeromonas hydrophila in fcommon carp (Cyprinus carpio)
Today, the uses of medicinal plants as a growth stimulant and immunity improver have found a special place in the aquaculture industry. In this study, the effect of eucalyptus essential oil on hemato-immunological parameters, growth performance and resistance against Aeromonas hydrophila were evaluated. 240 carp (mean weight 53.64 ± 0.060) were divided into four treatments including a control g...
متن کاملEffects of dietary exposure to aflatoxins on some plasma biochemical indices of common carp (Cyprinus carpio)
Aflatoxins are a group of secondary fungal metabolites that occur widely in natural contaminants of many feeds under high humidity and temperature, and are potentially dangerous to fish. Therefore, this study was designed to investigate the effects of aflatoxins on some plasma biochemical indices, as clinical biomarkers, in common carp, Cyprinus carpio. Fish were fed diets contaminated with 0 (...
