Diet and feeding habits of two endemic demersal bycatch elasmobranchs: Trygonorrhina fasciata & Dentiraja australis

Ichthyological Research Aims and scope Submit manuscript


This study describes diet and feeding habits of two common bycatch elasmobranchs in East Australia: The Eastern Fiddler Ray Trygonorrhina fasciata (Muller & Henle, 1841) and the Sydney Skate Dentiraja australis (Macleay, 1884). Using stomach content analysis, we describe diet composition, food preferences and trophic levels of these batoids. Crustaceans were major components in the diet of both species which included teleosts and cephalopods. There was no indication of sex-related distinction in the diet of either species. The estimated trophic level (TL) of the T. fasciata was TL = 3.36 and the D. australis was TL = 3.43.
