Abstract

The correlation between hematology and plasma chemistry was examined in natural silver crucian carp Carassius langsdorfii. Three microsatellite DNA markers identified five clonal lines. Blood was obtained from the caudal vessels and analyzed using automatic analysis systems. The correlation between several parameters including erythrocyte count (RBC), mean corpuscular hemoglobin concentration (MCHC), alkaline phosphatase (ALP), plasma glucose (Glu) and total protein (TP) was assessed by liner regression. Hemoglobin (Hgb) and hematocrit (Hct) as a function of the erythrocyte count, hematocrit as a function of the hemoglobin, mean corpuscular hemoglobin (MCH) as a function of the mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC) as a function of the mean corpuscular hemoglobin, and total protein as a function of triglyceride (TG) were positively correlated for the five clonal lines. Different regression slopes (b-value) of RBC to Hgb and Hct were found among clonal lines, while no such differences were found among slopes of the remaining regression equation. This phenomenon suggests that the significantly different slopes among parameters, which indicated low genetic influence at the each parameter, clearly detected the genetic influences as the compound effect of these parameters.
