Abstract

In this study, some physiological responses of "tambaqui" Colossoma macropomum, submitted to capture and handling stress were evaluated. Changes were observed in red blood cell (RBC), white blood cell (WBC), hematocrit percentage, hemoglobin concentration, mean corpuscular volume (MCV), blood glucose and plasma cortisol. After stress, red blood cell, hemoglobin, and hematocrit decreased significantly while blood glucose, plasma cortisol, MCV, white blood cell number, lymphocytes and neutrophils numbers increased. MCHC, monocytes and special granulocytic cells numbers (SGC) did not show any change after the disturbance.
