Deriving
Benefits from Marine Biotechnology
Project Leader: Chris
Battershill
Description
Australia's Oceans Policy provides an integrated strategy
for the exploration and ecologically sustainable utilisation
of marine natural resources. Areas identified as research
priorities include enhancing the sustainable development of
aquaculture industries and the exploitation of marine genetic
resources for pharmaceutical and commercial use. This project
will deliver results in both of these areas.
Research in tropical aquaculture will focus on prawn
domestication and genetics, the culturing of new species, and
the improvement of methodologies to enhance industry
production.
The search for new biochemicals from Australia's diverse
marine biota will continue towards the development of
pharmaceuticals and healthcare products, agrochemicals for
crop protection, and novel bioremediation agents for
environmental protection. The search for novel biochemicals is
complemented by examining the adaptations of marine organisms
to harmful and aggressive environments resulting in the
production of biotoxins and venoms, antifoulants, signalling
agents, and other molecular defences. Understanding the
biochemical functioning of these agents has wide potential for
the rational discovery of new and useful marine products.
Government priorities from
Australia's Marine Science and Technology Plan
Aquaculture in Australia is projected to be worth $2.5
billion by 2010. Globally, biotechnology products
(pharmaceuticals, nutriceuticals, agrochemicals and industrial
or biomedical agents) have been valued at more than $US 200
billion this year. Prospects for capturing return from these
fields range from speculative (the chance of a major
discovery) to reliable (the chances of several niche products)
given adequate investment. Relevant priorities are:
- Program 1 Objective 6 To understand marine biodiversity
and biological processes in Australia's oceans
- Program 2 Objective 7 To improve the sustainability,
productivity and environmental performance of aquaculture
- Program 2 Objective 10 To promote the potential of new
and emerging industries, services and technologies
Major activities
- Strategic basic research into marine environmental
biochemistry and chemical ecology. The focus is on
understanding biochemical solutions that have evolved as
adaptations to different challenges (environmental stress,
communication, symbiosis). This basic understanding informs
the other, more tactical, components of the project.
- Support for existing and new aquaculture industries. The
main focus is upon the expanding industry in northern
Australia for the black tiger prawn; a global market worth
almost $US5 billion. AIMS research is designed to release
the Australian industry from its dependence upon a
vulnerable supply of wild broodstock and to improve the
quality of water discharged from prawn farms. Research into
new industries extends from domesticating new food species
to culturing sponges for the production of expensive fine
chemicals.
- Discovery of bioactive molecules from marine biota. AIMS
screens plants, animals and microbes for compounds that may
be used as agrochemicals and/or medicines. This search is
done intelligently by predicting which organisms are most
likely to have evolved original compounds with desirable
bioactivity.
Goals
- To enhance the production of tropical aquaculture species
- To identify new agrochemical and medicinal leads from
marine organisms
- To create opportunities for new marine industries based
upon biotechnology
- To understand and value marine biodiversity

Marine environmental biochemistry and chemical ecology
Tropical
aquaculture
Description
All levels of government have agreed on the requirement
that wild fisheries must be harvested on an ecologically
sustainable basis. Using this criterion, three-quarters of
Australia's wild fisheries are either fully or over-exploited.
Landings will therefore continue to plateau or decline, while
domestic and international demand for seafood is rising.
Aquaculture offers the main prospect of filling this gap and
ABARE forecasts that this industry has very substantial
potential for growth in Australia.
The Subproject seeks to facilitate the expansion of
profitable and sustainable aquaculture industries in tropical
Australia. Our current focus is the black tiger prawn (Penaeus
monodon), emphasising domestication, selective breeding and
enhanced production from pond-reared and wild-caught
broodstock. In the new triennium, we will extend this research
to cover other edible species (rock lobsters, fish) and
organisms that yield other products, such as drugs and fine
chemicals. To achieve these goals, the subproject will apply a
wide range of expertise from animal husbandry and reproductive
physiology through to biochemistry and molecular biology.
Objectives
- Develop methods for hormonal control of spawning of
Penaeus monodon
- Improve broodstock performance of domesticated lines of
Penaeus monodon
- Investigate domestication of new aquaculture targets (e.g.
tropical lobsters)
- Develop innovative technologies for sustainable seafood
production
Key outcomes
- Enhanced performance of the prawn aquaculture industry, as
measured by economic and/or environmental sustainability
indicators
- New opportunities for aquaculture industries in northern
Australia

APFA, FRDC, GBRMPA, QSIA, aquaculture farmers and
investors, marine conservation groups, recreational fishing

Bioactive
molecules from the marine environment
Description
The Australian marine environment is famed for its
megadiversity. To date, only a fraction of this diversity has
been explored for novel bioactive chemicals that can be
developed as new drugs and/or agrochemicals.
The research potential of this Subproject is founded upon a
comprehensive and fully curated collection of marine
biodiversity that the Institute has assembled over the last
decade. This large collection of macro- and microorganisms has
been captured in an advanced bioinformatics database that
allows the search for bioactive molecules to be focused
intelligently towards the best targets.
The same techniques used to discover these new marine
natural products can also be applied to the marine toxins that
contaminate seafood. Consequently, the Institute is also
following research to develop inexpensive but sensitive
diagnostic kits for this purpose.
On a different level, AIMS is contributing to a national
agenda to develop Commonwealth policy on access and benefit
sharing to biodiversity resources. Related negotiations are
underway with the States (as this volume goes to press, the
first joint agreement has been signed by the Premier of
Queensland) and Australia's position has been represented in
international forums considering these same issues.
Objectives
- To develop and commercialise technology for seafood
diagnostic kits
- To discover novel biomolecules with strong biocidal and
anti-infective activity
- To develop collaborative partnerships (industrial equity
ventures, regional research networks) to increase the volume
of screening and Australia's capacity to exploit promising
lead compounds
Key outcomes
- A safer seafood industry
- Strategic partnerships with industry
- Economic and social benefits from the discovery and
commercialisation of marine natural products through
public-private partnerships
- Improved knowledge of Australia's marine resources (marine
taxonomy)
- Improved access for all to marine biodiversity with fair
and equitable benefit sharing
Key clients and stakeholders
Australian governments (access and benefit sharing
policy), biotechnology companies (agrochemical,
pharmaceutical) and private investors, seafood industries

Marine
environmental biochemistry and chemical ecology
Description
Marine organisms produce myriad natural chemicals that
protect them from environmental stress, defend them against
predators, or act as chemical signals. An understanding of the
source and function of these unique compounds can hasten their
potential development for the benefit of medicine, industry or
the environment.
Past examples of this type of research at AIMS have
included the identification of powerful sunscreens and
antioxidants in reef corals and other marine organisms. The
advantage of the AIMS approach is that these compounds are
being discovered through fundamental research into the
mechanisms by which marine organisms protect themselves
against environmental stress. Such discoveries also provide
mechanisms for measuring levels of sublethal stress in wild
organisms that could be developed into early warning systems
for monitoring environmental health.
Objectives
- Study biochemical responses of marine organisms to
environmental stress
- Study biofilms as attractants and settlement triggers for
marine invertebrates
- Study chemical communication among marine invertebrates
- Clarify the role of symbionts in the biosynthesis of
selected bioactive metabolites
- Examine the sources of paralytic shellfish toxins in
Australian marine ecosystems
Key outcomes
- Identification of lead bioactives and/or novel
applications with potential to produce commercial, social or
environmental benefits to Australia
- New understandings of biochemistry and chemical ecology
that increase the efficiency and/or effectiveness of the
"intelligent search" for bioactive molecules
