Análise de parâmetros sorológicos de três espécies de tubarão do Arquipélago de Fernando de Noronha

Abstract

Documentation concerning reference values for blood biochemistry of sharks is rare in the literature. This research work was designed to provide mean values for several serum biochemical parameters of three shark species, Carcharhinus perezi, Ginglymostoma cirratum and Negaprion brevoristri, found in Fernando de Noronha Archipelago. Using a biochemical automated analyzer, eleven serum parameters were estimated, including glucose, creatinine, uric acid, sodium, potassium, calcium, phosphate, total protein, albumin, globulin and aspartate aminotransferase/AST. The parameters’ mean values for the three species were compared with one another and with reported values in the literature for those and other species of shark. The comparative analyses indicated that some mean values show variation among species, implying that potential blood biochemical changes which may occur in sharks are related to field sample collections, processing and storage, and/or stress associated with capture
