ABSTRACT

Objective. In view of the deficiency of information in the area of clinical pathology of elasmobranchs, mainly of the physiological parameters, the aim of this work was to study hematological parameters of the Zapteryx brevirostris species. Materials and methods. Four specimens apparently healthy of Zapteryx brevirostris; three females and a male were used. These animals are all pertaining ones to the Aquarium of Ubatuba, São Paulo (Brazil). Results. The obtained average of hematological values for the Zapteryx brevirostris were: Red Blood Cells were - 0.96 x 106/μL, Packed Cell Volume - 24.3% and White Blood Cells - 36.8 x 103/μL. Conclusion. Although the small N, which decreases the accuracy, this research has scientific value because the situation of vulnerability of Zapteryx brevirostris, suggesting other studies.

RESUMEN

Objetivo. En vista de la carencia de información en el área de patología clínica de los elasmobranquios, especialmente en lo que respecta a los parámetros fisiopatológicos, el objetivo de este trabajo fue el de obtener parámetros de la hematología de la especie Zapteryx brevirostris. Materiales y método. Cuatro animales clínicamente saludables de Zapteryx brevirostris; tres hembras y un macho fueron utilizados, todos procedentes del Acuario de Ubatuba, S. P. Resultados. Los valores promedio de hematología para el Zapteryx brevirostris fueron: glóbulos rojos - 0.96 x 106/ μL, volumen de los hematíes - 24.3 % y glóbulos blancos 36.8 x 103/ μL. Conclusiones. A pesar de la pequeña N, que disminuye la precisión, la investigación tiene valor científico debido a que Zapteryx brevirostris es una especie vulnerable; sugiriendo otros estudios.
