Diet of Chaceon notialis (Decapoda, Brachyura) off the coast of Rio Grande, RS, Brazil

Abstract
There are two species of the genus Chaceon (Geryonidae) inhabiting the southeastern and southern coastal waters of Brazil, Chaceon ramosae Manning, Tavares and Albuquerque, 1989, and Chaceon notialis Manning and Holthuis, 1989, commonly called royal crab and red crab, respectively, otherwise generally known as deep sea crabs. Both species have suffered enormous pressure as a result of deep sea fishing activity in the Brazilian Exclusive Economic Zone (EEZ) (ATHIÊ; ROSSI-WONGTSCHOWSKI, 2004).
Crabs of the genus Chaceon are epibenthonic and inhabit muddy and muddy-sandy bottoms between 100 and 2800 m isobaths (MANNING; HOLTHUIS, 1989). There is evidence that the species C. notialis occurring in Rio Grande coast belongs to the Uruguayan and Argentinean stocks, and thus represents an important resource common to those three countries (ATHIÊ; ROSSI-WONGTSCHOWSKI, 2004).
Studies on the biology of geryonid crabs inhabiting the Brazilian Exclusive Economic Zone (EEZ) are still few. The aim of the present study is to provide preliminary data on the composition of the diet of Chaceon notialis living in the coastal waters off Rio Grande.
