Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. The dual frequency identification sonar (DIDSON) will also allow accurate and standardised study of fish movements in response to floods, algal blooms or re-stocking events without disturbing the fish or their habitats. This will enhance our understanding of the top-down control by fish of aquatic ecosystems that are directly adjacent to human activity.

许多澳大利亚人享有海洋和淡水资源，我们正在以越来越快的速度开发渔业和水道。有效的渔业管理需要了解鱼类的丰度和行为。该设施将为研究人员提供新的声学视频技术，以计算堰附近、码头或原木下以及海草床内的鱼类和鲨鱼。双频识别声纳（DIDSON）还将允许准确和标准化的鱼类运动研究，以应对洪水，藻华或重新放养事件，而不会干扰鱼类或其栖息地。这将增进我们对鱼类自上而下控制与人类活动直接相邻的水生生态系统的理解。
