Resumo: 	This Study was carried out at the Salmoniculture Experimental Station "Dr. Ascanio de Faria", in Campos do Jordão, São Paulo. Brazil. The aim was to compared the hematology of triploid and diploid rainbow trout, Oncorhynchus mykiss Walbaum, 1792, by sex and gonadal maturation stages. Blood was obtained from 144 individuais for determinati-ons of: haemoglobin rate (Hb), haematocrit (Ht), erythrocyte count (Er), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MHC), mean corpuscular hemoglobin concentration (MCHC), and differential leucocyte counts. The ploid was determinated by measuring the erythrocyte major axis, in fresh and stainncd smears. Triploid rainbow trout had a large eiythrocyte diameter, mean erythrocyte volume and mean haemoglobin concentration, but lower erythrocyte count than diploid. Lymphocytes was the most frequent cell in peripherical blood.There was no dilTerence between males and females for ali parameters here analysed. The haematological analyses showcd signiffleant increase with the dcvelopment of gonadal maturation stages.
