Eritrograma de híbridos de surubim (Pseudoplatystoma reticulatum X P. coruscans) mantidos em diferentes densidades de estocagem

Abstract

The blood profile of hybrid fish was studied. Pseudoplatystoma (P. coruscans X P. reticulatum) were submitted to different stocking densities in recirculating water system in two distinct phases of production. Hemoglobin concentration (Hg), packed cell volume (PCV) and mean corpuscular hemoglobin concentration (MCHC) were evaluated. There was no difference between the studied densities. Hemoglobin concentration, PCV and MCHC remained within the normal range for teleost fish.
