Métricas alimentarias de dos condrictios meso-bentónicos en aguas de Chile central

Little has been studied of the food metrics most chondrichthyans, which provide baseline information for assessment fishing status to guide development ecosystem-based management plans. Therefore, main goal this study was approach isotopic niche Dipturus chilensis and Callorhinchus callorynchus in Valparaíso (central Chile). The findings showed that C. presented a narrow ellipse (E= 0.79; RC= 4.14; θ= 1.39), meanwhile D. chilensis, an with greater extension 0.95; 8,23; -0.11), therefore wide niche.
