Hematological parameters of three species of the peacock bass (Cichla spp.) from Balbina lake, Presidente Figueiredo, Amazonas, Brazil

Abstract The objective of this study was to characterize and compare the hematological variables (erythrogram, thrombogram, leukogram plasma metabolites) three cichlid species: Cichla monoculus, temensis vazzoleri. A total 45 specimens were captured in Balbina lake, Presidente Figueiredo, Amazonas, Brazil, with aid a rod reel or hand line, natural artificial bait: 15 C. Their blood removed by means caudal puncture dorsal aorta, data determined accordance methodology previously described literature. erythrogram showed similarities between species, while thrombogram differences vazzoleri other species studied (C. monoculus temensis). leukocyte counts for higher than those monoculus. predominant lymphocytes, whereas it monocytes metabolites regarding their glucose, cholesterol, urea potassium levels. It is concluded that these present differentiation, thus indicating they have differentiated blood-cell immune responses metabolite physiology.
