Therefore, the main goal of this study was to approach the isotopic niche of Dipturus chilensis and Callorhinchus callorynchus in the Bay of Valparaíso (central Chile). The main findings showed that C. callorynchus presented a narrow ellipse (E= 0.79; RC= 4.14; θ= 1.39), meanwhile D. chilensis, presented an ellipse with greater extension (E= 0.95; RC= 8.23; θ=-0.11), therefore a wide isotopic niche. © The author(s).esEcosystem-based fisheries managementFood websIsotopic nicheStable isotopesChileValparaiso BayValparaiso [Chile]BenthosEcosystem managementFishFishery managementNicheFood metrics of two meso-benthic chondrichthyans in waters of central ChileMétricas alimentarias de dos condrictios meso-bentónicos en aguas de Chile centralArtículoCC BY-NC 4.0 DEED Attribution-NonCommercial 4.0 International10.22370/rbmo.2022.57.Especial.3201
