Resumo: This study evaluated the hematological characteristics and erythrocyte morphometry in Auchenipterus nuchalis, Psectrogaster amazonica and Squaliforma emarginata captured in Tocantins river. The samples were taken in the Tocantins river, where blood was collected by puncturing the caudal vein of the animals. The complete hemogram and morphometry of the erythrocytes were determined. Auchenipterus nuchalis (n = 15) showed the largest number of erythrocytes, hemoglobin and hematocrit, followed by P. amazonica (n = 26) and S. emarginata (n = 26). Squaliforma emarginata showed the largest erythrocytes and the smallest number of circulating cells. Squaliforma emarginata also showed the highest number of circulating blast cells (orthochromatic and polychromatophil erythrocytes) in the peripheral blood. These differences can be attributed to respiratory adaptations of a behavioral or physiological nature related to the environment. The highest percentage of lymphocytes was observed in P. amazonica, and of monocytes and neutrophils in A. nuchalis. The variation among the species in the percentages of leucocytes can also be attributed to the niche occupied, favored by exposure to different microorganisms.

As amostragens foram realizadas no rio Tocantins, onde o sangue foi coletado por punção caudal dos animais, determinando-se hemograma completo e morfometria dos eritrócitos. Auchenipterus nuchalis (n = 15) apresentou maior número de eritrócitos, hemoglobina e hematócrito, seguido de P. amazônica (n = 26) e S. emarginata (n = 26). O tamanho dos eritrócitos foi maior para S. emarginata, mostrando que quanto maior o tamanho dos eritrócitos, menor o número de células circulantes. Squaliforma emarginata também apresentou maior número de blastos (eritrócitos ortocromáticos e policromatófilos) no sangue periférico. Estas diferenças podem ser atribuídas a adaptações respiratórias de natureza comportamental e/ou fisiológicas, relacionadas ao meio ambiente. O maior percentual de linfócitos foi observado em P. amazônica; o de monócitos e neutrófilos, na espécie A. nuchalis. A variação nos percentuais de leucócitos entre as espécies pode estar relacionada ao nicho ocupado, favorecido pela exposição a diferentes microrganismos.Universidade Estadual De Maringá2009-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/102410.4025/actascibiolsci.v31i2.1024Acta Scientiarum.
