Aquaculture
SARDI's aquaculture science program provides technical advice across government, industry and the community. Our work is crucial to the development of South Australia’s aquaculture industry.
The objectives of this program are to:
- develop new technologies, species and sites for aquaculture
- enhance the competitive advantage and value of existing aquaculture industries
- minimise risks for new and existing aquaculture entities
- contribute to education and training.
Research areas
Our expertise includes the sustainable development and management of aquaculture in fresh, brackish, and marine environments.
We focus on a range of aquatic organisms which are now farmed, including:
- southern bluefin tuna
- pacific and native oysters
- greenlip abalone
- yellowtail kingfish
- barramundi
- microalgae
- macroalgae (seaweeds)
- salmon
- trout
- mulloway
- blue mussels
- yabbies
- marron.
Aquaculture has 4 subprograms.
Algal production and SEA laboratories
Algal production and SEA laboratories
With a focus on microalgae and macroalgae (seaweeds), this subprogram provides clients with:
- concept design
- laboratory testing
- proof-of-concept scale trials
- commercial scale trials.
We achieve this through in-house skills, collaborations and specialised infrastructure.
We also provide practical and cost-effective algal production systems for:
- food and functional food
- natural food pigments and colourants
- nutraceuticals
- cosmeceuticals
- live feed for aquaculture
- bioenergy
- biofixation of carbon
- nutrient remediation.
Finfish and shellfish aquaculture
Finfish and shellfish aquaculture
This subprogram supports the expansion of aquaculture production. Our research activities include:
- propagating new species
- improving hatchery rearing of marine finfish and shellfish species
- developing sustainable aquaculture production systems
- advising on economic and environmental issues of aquaculture for finfish and shellfish
- creating and evaluating techniques to enhance the efficiency of our aquaculture industries in an international marketplace.
Animal biotechnology
Animal biotechnology
This subprogram advises on the development and application of molecular tools, used for assessing the health and nutritional status in:
- aquaculture species
- poultry
- livestock.
Our work involves:
- understanding ecosystem dynamics through DNA dietary testing of marine apex predators
- using the host associated microbiome for assessing nutritional health and productivity
- developing and reviewing environmental tests that detect marine pests
- using molecular probes to discriminate egg and larval stages from key fisheries species, providing a robust measure of biomass
- evaluating and manipulating gut microbiomes to improve feed utilisation.
Nutrition and feed technology
Nutrition and feed technology
This subprogram advises on the provision of nutritionally complete and cost-effective diets for fish and shellfish. These address the aquaculture industry’s:
- diet-related productivity and health
- product quality
- marketing issues.
We develop and evaluate both existing and new technologies, for diet development and feeding strategy. Our work provides:
- emerging industries with the necessary diets
- established industry with technologies.
