Variações na forma do otólito sagitta de Coryphaena hippurus (Actinopterygii: Coryphaenidae) em uma área de ressurgência na costa sudoeste do Oceano Atlântico

Abstract: RESUMO Os otólitos são estruturas espécie-específicas de peixes cuja análise morfológica é uma ferramenta eficiente para identificação e discriminação de estoques e/ou populações sujeitas a variações clinais. O presente trabalho buscou elucidar o grau de variação morfológica dos otólitos sagitta do dourado, Coryphaena hippurus Linnaeus, 1758 capturado ao largo da costa sudeste do Brasil pela frota pesqueira sediada no Rio de Janeiro. Os 164 pares de otólitos analisados foram obtidos a partir de amostras coleta… Show more

“…This study is pioneering for the Maranhão Amazon coast region, serving as a parameter for evaluating fish biology and future age and growth studies (Almeida et al, 2020). The results acquired from the morphometric and morphological relationships between otoliths and individuals of B. bagre, L. synagris and N. microps can be carried out as financial, methodological and faster cost-benefit methods compared to other otolith studies.…”

“…1830), representing the families Arridae, Lutjanidae and Sciaenidae, respectively, have a wide distribution along the Brazilian coast and are highly valued commercially in the state of Maranhão (Acero, 2022;Bernardo et al, 2011;Carvalho-Neta et al, 2011;Fisher, 1978). Although past studies have addressed the fisheries biology of these species, including stock identification, population structure (Casatti et al, 2015;Correia et al, 2021) growth, and reproductive biology (Fernandes et al, 2022), as well as the weight-length relationship (Almeida et al, 2020) there is a need for further investigations to understand the population dynamics of these animals.…”
