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.

两种地方性底层兼捕弹鳃类动物的饮食和摄食习惯：Trygonorrhina fasciata 和 Dentiraja australis

本研究描述了东澳大利亚两种常见的兼捕弹鳃类动物的饮食和进食习惯：Eastern Fiddler Ray Trygonorrhina fasciata (Muller & Henle, 1841) 和 Sydney Skate Dentiraja australis (Macleay, 1884)。使用胃内容物分析，我们描述了这些蝙蝠的饮食成分、食物偏好和营养水平。甲壳类动物是包括硬骨鱼和头足类动物在内的两个物种饮食的主要成分。没有迹象表明这两种物种的饮食存在与性别相关的差异。T. fasciata 的估计营养级 (TL) 为 TL = 3.36，D. australis 为 TL = 3.43。
