Tropical aquaculture
"Developing technology to enhance
sustainable tropical aquaculture production for industry and the
community"
Aquaculture is
the fastest growing food production sector in the
world and the fastest growing primary industry in the
Indo-pacific region.
|
The value of the Australian aquaculture
industry has trebled over the past ten years and is
now worth more than $700 million.
The demand for seafood is outstripping sustainable harvests
from wild populations and there is increasing pressure on
aquaculture and fishing industries to develop and adopt
sustainable practices.

The tropical
aquaculture team |
The Australian Government wants
aquaculture production to triple by 2010. The AIMS Tropical
Aquaculture team is helping the industry to meet this target
by addressing production and environmental issues
restricting profitability and expansion of current tropical
aquaculture industries, and by working with industry and
community partners to develop new aquaculture industries for
tropical Australia. |
Aquaculture is the
fastest growing food production sector in the world. It is the
only environmentally sustainable means of meeting increases in
the global demand for seafood. The Australian and
Queensland Governments have set ambitious targets for the
expansion of northern Australia’s aquaculture industry and
this team addresses key obstacles stifling growth of existing
tropical aquaculture industries. AIMS also works towards
development of new aquaculture industries.
Projects include culture of
tropical lobsters for food, and sponges for bath and industrial use, and for
chemical products. This team is your one-stop-shop when it comes to
innovative approaches to tropical aquaculture industry research and
development. From rock lobsters to black tiger prawns, land-based and
in-sea, high and low-tech culture systems… the Tropical Aquaculture team is
working closely with industry and community stakeholders.
Our Team
The Tropical Aquaculture
team (takes you to profile) has expertise in systems design,
hatchery technology, broodstock production and physiology, water
quality management, live foods, reproductive biology and
endocrinology, disease, molecular biology, genetics and coastal
ecology. This allows AIMS to address most aspects of aquaculture
production in its research, ranging from the initial production of
larvae through to measuring potential environmental impacts of
aquaculture production.
Key projects
The Aquaculture team is making
great strides in understanding the process required to rear black
tiger prawn broodstock in captivity on a commercial scale, a
feat that has so far eluded the tiger prawn industry worldwide. The
aim of the project is to reduce the industry’s reliance on
broodstock from the wild, a practice fraught with supply and demand,
and disease problems. AIMS aquaculture researchers are working
together in a major collaboration with the Australian Prawn Farmers
Association, two prawn farms and the CSIRO and Qld DPI&F. Key
results include the finding that the ability to reproduce
successfully in captivity may have a genetic basis, allowing
researchers to apply selective breeding techniques to select for the
best captive breeders. AIMS researchers have also used sensitive new
assays for important viruses known to cause disease in prawns to
show that even the act of handling broodstock can stress them to a
degree that leads to rapid viral multiplication and may increase
mortality.
It is hoped prototype
sponge farms set up by AIMS in collaboration with indigenous
communities off the coast of Queensland, in Arnhem Land and the
Torres Strait will provide new employment and training opportunities
in remote areas of tropical Australia. These farms will grow sponge
species sourced from local waters to produce natural sea sponges for
industrial, cosmetic and bath use for under supplied international
markets. The objective is to develop low-tech in-sea aquaculture
techniques compatible with the customs of the communities where
they’re located. AIMS has also pioneered aquaculture of sponges near
its Western Australian facility to produce chemicals needed for
pre-clinical trials of promising drug leads.

"Collaborating with Arnhem Land Sea Rangers"
These sea rangers at the
community of Warrawi and Maningrida in Arnhem Land are putting
in a trial sponge farm, in collaboration with AIMS scientists.
It’s just one of the innovative aquaculture technologies being
pioneered by the AIMS Tropical Aquaculture team.

Innovative solutions
Molecular techniques are used to track
and manipulate the microbial community in larval rearing
systems. Similar approaches will be used to identify the gut
contents of fish and crustacean larvae, to inform development of
suitable larval diets.

research supports the nation’s
aquaculture industry
Another major research focus
is the tropical rock lobster. AIMS is collaborating with Qld
DPI&F and with a commercial partner to develop the technology to
establish a new aquaculture industry based around one of Australia’s
most valuable wild fishery exports. The greatest challenge is
developing commercial scale hatchery technology to grow the larvae
through the six months that may be required until they develop into
recognisable baby lobsters. The project examines hormonal control of
larval development, nutrition and the microbiology of rock lobster
larval rearing.
The aquaculture team is
expanding its research to include the development of strategies to
minimise the impact of aquaculture discharges – a sticking
point constraining the growth of the industry in northern Australia.
This work will help Australia’s aquaculture industry meet strict new
environmental standards.
Our Location
AIMS has a competitive
advantage in the field of tropical aquaculture research by virtue of
its physically isolated location on Cape Ferguson, with a large land
area right on the coast. The site adjoins a limited access
"Scientific Research Zone" with some of the cleanest seawater in the
region. Seawater for the Institute is sourced directly from an
offshore intake and is relatively free from human activity. Fully
integrated rearing facilities (hatchery, growout and maturation) are
located adjacent to a new, state-of-the-art biotechnology
laboratory, allowing immediate application of biotechnology tools to
the aquaculture of target species. AIMS also has fully equipped
research vessels enabling access to sites for in-sea
experimentation, and it is located amidst the primary prawn
aquaculture region in the country, giving it direct access to
industry.
Our Collaborations
Important research
collaborations have been achieved with:
- industry partners in the prawn and seafood industry,
- other research providers such as CSIRO and the Queensland
Department of Primary Industries and Fisheries,
- universities including James Cook University and the
University of Queensland
- indigenous community groups off the east Queensland coast, in
the Torres Strait and in Arnhem Land
- overseas universities and research providers
