Thus, the present study evaluated feeding rate and feeding frequency effect for growth performance and health of Heros severus fingerlings. An experiment was carried out in completely randomized design with two feeding frequencies (2 and 4 times a day), three feeding rates (3%, 6% and 9% of body weight.day−1) and three replicates for 90 days. No differences were observed (p &gt 0.05) in the growth performance for fingerlings between two and four feeding frequencies, but lower feeding frequency (two times a day) caused lower uniformity for weight at the end of 90 days. Furthermore, the increase in the feeding rate from 3% to 6% or 9% (biomass.day−1) promoted higher weight and length gain, specific growth and length ratio (SGRL, SGRw) and biomass gain (p &lt 0.05). Lower feeding rate also caused blood change such as reduced values for glucose, triglyceride, erythrocyte, thrombocytes and leukocytes. Thus, H. severus fingerlings can be reared using feeding rate 6% (Biomass.day−1) with two meals a day for better utilization of the feed without affecting its hematological parameters.  aAnimal feeding operations  aFish  aOrnamental fish  aAlimentação  aPeixe  aPeixe Ornamental1 aSOUSA, N. da C.1 aCOUTO, M.
