Brief description Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. 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.
