Hematological and plasm biochemical values for Rhinogobio ventralis in the Yangtze River, China

Abstract

Fish blood parameters can be used as potential indicators for identification of stress caused by environmental factors. This study aimed to establish a "normal" hematological profile for the Rhinogobio ventralis and to provide the basis for future comparative surveys. The hematological and plasma biochemical parameters were measured in the cyprinid species, R. ventralis, collected from the upper reaches of the Yangtze River. The concentrations of red blood cell count, white blood cell count, hematocrit, hemoglobin, mean corpuscle volume, mean corpuscle hemoglobin, Cl⁻, Ca²⁺, creatinine, urea, glucose, plasma total protein, plasma albumin, globulins, triglyceride, cholesterol, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase were obtained. The results revealed that no significant differences were found in the hematological and plasma parameters between different sexes when they were analyzed with the independent samples t test. Compared with other fish species, it is hard to find hematological and plasma parameters that can be used as a species-specific physiological indication, and there were no sex-dependent blood parameters in the present study.
