The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding, prey manipulation and the role of critical senses in the only captive population of sawfishes in Australia. Such knowledge will underpin the development and use of visual, chemical and/or magnetic repellents by fisherman that are still responsible for the loss of large numbers of sawfish as by-catch.

卡奔塔利亚湾是世界上最后一个拥有可持续数量的锯鳐的栖息地。由于很容易被网缠住，锯使澳大利亚的种群数量急剧减少，所有物种都受到澳大利亚环境保护和生物多样性保护法的保护，包括濒危物种国际贸易公约（CITES）。这项研究将提供基本的生物学信息的喂养，猎物操纵和关键感官的作用，在澳大利亚唯一的圈养种群的锯鳐。这些知识将有助于渔民开发和使用视觉、化学和/或磁性驱避剂，而这些驱避剂仍然是造成大量副渔获物锯鳐损失的原因。
