Here we present the weight-length relationship of the spinner shark (Carcharhinus brevipinna) on the continental shelf of southern Brazil, estimated from an analysis of 125 specimens. No significant differences between males and females, so the data were grouped in equation W = 0,003L 3.1534 . The results presented here are the first to approach sharks above 75 cm and confirm the positive allometric growth of the species.
RESUMOAqui apresentamos, a relação peso-comprimento do tubarão-rotador (Carcharhinus brevipinna) na plataforma continental do sul do Brasil, estimada a partir de análise de 125 exemplares. Não houve diferenças significativas entre machos e fêmeas, portanto os dados foram agrupados na equação W = 0,003L 3.1534 . Os resultados aqui apresentados são os primeiros a abordarem tubarões acima de 75 cm e confirmam o crescimento alométrico positivo da espécie.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
