Sharks are vital components of marine ecosystems and contribute significantly to ecotourism and fisheries. Due to their slow rate of growth and reproduction, sharks are susceptible to over exploitation. A lack of knowledge regarding their behaviour and movement patterns is a key impediment to effective management. This project aims to examine social interactions and migration patterns of Port Jackson sharks using a unique combination of genetic techniques, novel acoustic tag technology, behavioural manipulations and modern social network analysis. Once verified, the approach developed can be applied to other marine predators of particular management concern. The data generated will directly inform fisheries and conservation management policy.

鲨鱼是海洋生态系统的重要组成部分，对生态旅游和渔业作出了重大贡献。由于生长和繁殖速度缓慢，鲨鱼很容易被过度捕捞。对他们的行为和行动模式缺乏了解是有效管理的一个主要障碍。本项目旨在利用基因技术、新型声学标签技术、行为操纵和现代社会网络分析的独特组合来研究杰克逊港鲨鱼的社会互动和迁徙模式。一旦得到证实，所制定的方法可应用于其他特别需要管理关注的海洋捕食者。所产生的数据将直接为渔业和养护管理政策提供信息。
