Investigation of Some Immunological Parameters in Rainbow Trout (Oncorhynchus mykiss) Injected Propolis
Keywords:Fish, Immunity, Immunostimulant, Propolis, Total protein
AbstractIn this study, effects of propolis on immunological parameters of rainbow trout were investigated. For this purpose, propolis was intraperitoneally injected to fish 4 times at doses of 2.5, 5 and 10 mg / kg fish weight. Blood samples on 3, 9, 15 and 21 days were collected from fish of the control and experimental groups and analysed to determine oxidative radical production [nitroblue tetrazolium (NBT) activity], total plasma protein and total immunoglobulin levels. At the end of the experiment, there was a statistically significant increase in oxidative radical production, total protein and immunoglobulin levels of propolis treated groups when compared to the control group.
