Aquaculture

Macquarie Harbour SalmonSalmon farm

The salmon industry is improving efficiency, productivity and environmental practices by using sensing technology placed on 'sentinel' fish in pens and in the environment to collect real-time data on fish behaviour, water temperature, dissolved oxygen and depth.

This $700,000 Project (Sense-T $638,000) brings together the Tasmanian Salmonid Growers' Association, IMAS and CSIRO to collect and analyse data from salmon farms in Macquarie Harbour.  

Sensors have been attached to individual 'sentinel' fish in pens in addition to sensors in the environment.  Data is being collected on fish behaviour as well as environmental conditions such as water temperature, dissolved oxygen and depth.  

The Project is:


Oyster BiosensorsAquaculture

Fitting a network of biosensors on individual oysters to collect data on health and on-farm conditions is informing real-time decision making on production. The industry is becoming more competitive, efficient and sustainable.

IMAS and CSIRO are working together on this $1.4 million Project (Sense-T $652,000) to further progress research begun under Sense-T's Stage 1 Aquaculture Project.  

Opportunity

Tasmania has a reputation for premium oysters - with excellent growing areas located on the North, East, and South-East coasts. However, oysters can be susceptible to changing environmental conditions such as freshwater input and rapid change in temperature, which can slow their growth or cause mortalities.

Solution

The Project is developing and trialling a network of oyster and environmental biosensors. These biosensors record oyster heartbeat and metabolism, and match this with environmental changes in temperature, salinity, pH, dissolved oxygen, turbidity and algal abundance. Monthly measurements of growth and oyster condition aim to link all of these parameters, and this information will be used to develop farm management models that maximise oyster production.

Impact

Having real-time environmental data available to oyster farmers is helping the industry become more competitive, efficient and sustainable. Demonstrating how conditions affect oysters is enabling producers to better manage their stock, helping to reduce oyster stress and improve growth.

Project partners include; Barilla Bay Tasmania, Oysters Tasmania, Bolduans Bay Oysters, Tasman Sea Products and Shellfish Culture Ltd.

About Sense-T's Industry Research Projects

Sense-T's Aquaculture Projects are among 14 Industry Research Projects currently being undertaken. The Projects have received funding of $6 million from the $13 million provided to the University of Tasmania for Sense-T by the Australian Government through the Tasmanian Jobs and Growth Plan, with a further $5 million contributed by our research and industry partners.
