This Sense-T project brought together the Tasmanian Salmonid Growers' Association, IMAS and CSIRO to collect and analyse data from salmon farms in Macquarie Harbour. Sensors were attached to individual 'sentinel' fish in pens in addition to sensors in the environment. Data was collected on fish behaviour as well as environmental conditions such as water temperature, dissolved oxygen and depth. The aims of the project were to: help to reduce feed wastage by ensuring fish are fed when environmental conditions are suitable; collect new or previously difficult to obtain information about the harbour environment and the impact of salmon farming on variables such as oxygen levels; improve the salmon industry's efficiency and productivity; provide real-time data to support decision-making; and, highlight areas where the industry could improve its environmental practices.
