The use of otoliths and bones of the head for the identification of two species of the genus Merluccius, in studies of prey-predator
A comparative osteological analysis of 6 bones and the sagitta otolith in Merluccius hubbsi and M. australis, two species that live in Southwest Atlantic, has been carried out. The objective was to contribute to identifying these two species as prey in the diet studies, and further description of th...
