Feeding ecology of elasmobranch species in southeastern Brazil

This dataset contains the digitized treatments in Plazi based on the original journal article Viana, Alessandra F., Valentin, Jean L., Vianna, Marcelo (2017): Feeding ecology of elasmobranch species in southeastern Brazil. Neotropical Ichthyology 15 (2): e 160176, DOI: 10.1590/1982-0224-20160176, URL: dx.doi.org/10.1590/1982-0224-20160176 The feeding ecology of five elasmobranch species was studied on the southern coast of Rio de Janeiro, southwestern Atlantic Ocean.

The specimens were caught with a trawl or bottom longline between January 2006 and August 2007. The diets of Psammobatis rutrum and Psammobatis extenta appeared to be basically carcino-benthophagous, with a very small niche width. Rioraja agassizii was basically carcino/ichthyo-benthophagous, also with a narrow niche, including teleost fish and shrimp, but in different proportions according to age and sex.
