Investigation of Some Immunological Parameters in Rainbow Trout (Oncorhynchus mykiss) Injected Propolis

Muhammet Enis Yonar, Naim Sağlam, Seval Yılmaz


In 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.
