Efecto de la hipoxia en la conducta de forrajeo de Cancer setosus (Molina, 1782) (Crustacea: Decapoda) alimentado con Mytilus chilensis (Hupé, 1854)

The variability in oxygen conditions results in different responses at marine organism's foraging behavior. In this sense, the aim of the paper was to study the foraging behavior of Cancer setosus (Molina, 1782) quantified through the size of prey selection and consumption rate under hypoxia an...
