Managing shark populations is a global priority, particularly in Australia with its extensive coastline and diverse marine ecosystems. However, inadequate data on shark behaviour and habitat use complicates efforts for sustainable management, posing risks to both apex predators and marine ecosystems. Beyond population threats, the absence of effective management disrupts marine food webs and ecosystem stability. Sharks, as keystone predators, play a vital role in regulating prey populations. Their depletion can trigger unchecked meso-predator growth, leading to ecosystem imbalances and potential collapse.
This significance is starkly evident along Queensland’s coast, where sharks shape marine ecosystem function. Understanding their habitat preferences and movements is crucial for effective fisheries management, especially given concerns about human-shark interactions. In Queensland, this research delves into how environmental changes impact bull shark populations, crucial for informing management and conservation strategies. Analysing data from the Queensland Shark Control Program sheds light on trends and environmental factors affecting bull shark abundance. Moreover, the project delves into bull shark ecology to better grasp habitat utilisation and risks posed to humans. Addressing high catch rates in areas underscores the need for refined data and targeted management approaches. Ultimately, research outcomes aim to enhance human safety while sustaining healthy marine ecosystems.
