Abstract

Specimens of cultivated Leporinus macrocephalus (piauçu) and Piaractus mesopotamicus (pacu) were collected in a fishfarm at Franca, SP. Effects of parasite infection upon hemoglobin, hematocrit, mean corpuscular hemoglobin concentration (MCHC), condition factor (Kn) and differential count of defense cells (leucocyte and thrombocyte) were evaluated. Both fish species were parasitized by monogenean; monogenean and Trichodina sp; monogenean and Lernaea cyprinacea; monogenean and Piscinoodinium pillulare; monogenean and Ichthyophthirius miltifiliis; monogenean, I. multifiliis and Trichodina sp. Parasitism did not influence (p > 0.05) the studied haematological characteristics in L. macrocephalus and P. mesopotamicus. Linnear regression showed negative correlation (p > 0.05) between lymphocytes and thrombocytes in L. macrocephalus and positive correlation (p > 0.01) of the hemoglobin rate with fish weight and fish length in P. mesopotamicus.
