The objective of this study was to evaluate if there were alterations in hematological variables of fish after transportation and exhibition at an agricultural fair. We first collected blood samples from 12 fish of the species Prochilodus lineatus (curimbata) at the Goio-En research institute; then, these animals were transported (60 km) to the agricultural fair, where they stayed for 3 days in glass aquariums exposed to the visitors of the event. On the return of the fish to the institute, we collected blood again. We performed hematological analyses, measuring hematocrit, hemoglobin concentration, and total erythrocyte count in the harvested material. We also determined mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. Total leukocyte counts and leukocyte differential performed on blood smears. There were no differences in hematocrit, hemoglobin, mean corpuscular hemoglobin, leukocyte, lymphocyte, neutrophil, and monocyte concentration (P > 0.05) before and after the fair. However, the number of erythrocytes and thrombocytes were lower after the fish show (P
