Determination of Reference Values of Some Hematological and Immunological Parameters in Healthy Russian Sturgeon (Acipenser gueldenstaedtii)
Abstract
This study aims to determine the reference intervals of some hematological and immunological parameters in healthy Russian sturgeon (Acipenser gueldenstaedtii Brandt & Ratzeburg, 1833) blood. These parameters are important indicators of fish physiological status and fish health. In the study, reference ranges of erythrocyte, leukocyte, lymphocyte, monocyte, eosinophil, neutrophil, basophil, and hematocrit values were determined for hematological parameters. In terms of immunological parameters, the reference intervals of TNF-α (tumor necrosis factor-alpha), IFN-γ (interferon-gamma), IL-1β (interleukin 1 beta), IL-6 (interleukin 6) and IL-8 (interleukin 8) values were determined. The reference ranges we have detected; erythrocyte 0.77–1.23 × 106/mm3, leukocyte 9.21–16.96 × 103/mm3, lymphocyte 43.35–59.78%, monocyte 4.61–11.39%, eosinophil 3.27–6.52%, neutrophil 12.16–18.41%, hematocrit 22.14–28.63%, TNF-α 27.59–49.83 pg/ml, IFN-γ 66.25–79.34 pg/ml, IL-1β 1.08–1.76 pg/ml, IL-6 11.2–19.7 pg/ml and IL-8 31.4–52.7 pg/ml. It is thought that the hematological and immunological reference intervals detected in the Russian sturgeons which will contribute significantly to the determination of the health and physiological situation of these fish.
