Australian Centre for International Agricultural Research - Fisheries Program

Addressing key technical bottlenecks in the grouper supply chain in Vietnam and Australia through manufactured feed and hatchery developments that aim to improve sector profitability

Indicative Funding
$2,500,000 over 3 years
Summary
The project aims to address key bottlenecks in the aquaculture grouper supply chain in Vietnam and Australia through research into nutritional constraints and drivers for commercial feed adoption by the Vietnam grow-out farming sector, as well as factors affecting the supply of high-quality eggs, larvae and juveniles in both Vietnam and Australia. A physiological approach to nutrient requirements and feeds development will be applied to address nutrient-related production bottlenecks for grouper aquaculture. This project will develop commercially implemented feed formulated specifically for grouper, facilitating the further development of the industry in Vietnam and Australia.

ARC Research Hub for Supercharging Tropical Aquaculture Through Genetic Solutions

Indicative Funding
$4,996,503 over 4 years, in partnership with Australian Genome Research Facility ($150,000); Cygnet Bay Pearls PL ($500,000); Mainstream Aquaculture ($500,000); Sea Forest Pty Ltd ($500,000) and THE COMPANY ONE PTY LTD ($500,000)
Summary
This project aims to integrate cutting edge genetic and genomic approaches into innovative aquaculture enterprises that farm in tropical northern Australia. It will deliver the requisite genetic knowledge to instigate world-leading and highly productive breeding programs for five species (barramundi, pearl oyster, prawn, grouper and marine seaweed), along with a novel understanding of the genetic basis of disease resistance and how the production environment interfaces with the bacterial microbiome, pathogens and water quality to cause disease. It will increase Australia's capacity to deliver advanced genetics outcomes to the aquaculture sector, while increasing productivity, international competitiveness, and lowered risk due to disease.

Australian Export Grains Innovation Centre Limited (AEGIC) - Contract Research

Evaluating Australian grains potential for Aquafeed in SE Asia

Indicative Funding
$27,608 over 1 year
Summary
Australia produces a range of grains and legumes that are routinely used for aquafeed in Australia, however their uptake in SE Asian markets appears to be limited. This project investigates opportunities and constraints of Australian grains and legumes in aquafeed production in Indonesia, Philippines, Thailand and Vietnam. It consists of a desktop study and report on opportunities and directions in this export market, followed by engagement with aquafeed specialists in these areas and scoping opportunities for research to test our assumptions around the most likely products in local feed production in-country.

Towards sustainable economic aquafeed for spiny lobsters

Indicative Funding
$50,000 over 1 year, in partnership with Ornatas ($50,319)
Summary
Aquaculture of the tropical lobster Panulirus ornatus is a recently commercialised industry in Australia. Recent review of nutritional knowledge of this species has revealed significant limitations to commercialisation of feeds, including data on key nutrient requirements, raw materials and feed processing. This project will begin to address these limitations, placing this industry on the path towards improved sustainable development.

CRC for Developing Northern Australia Scheme - Scholarship

Intensification of the redclaw crayfish (Cherax quadricarinatus) industry: the importance of sperm quality and male fertility to productivity.

Indicative Funding
$60,000 over 3 years
Summary
Expansion of the redclaw aquaculture industry is limited by suboptimal methods to produce fertilized eggs and craylings for pond production. Improvement of reproductive efficiency is dependent on several factors as well as understanding the underlying causes of subfertility. This project seeks to develop advanced reproductive technologies to characterise sperm quality; establish optimal diets; and develop artificial fertilization and sperm cryopreservation techniques for superior male broodstock to accelerate selective breeding.

Supporting grouper farming small holders in Vietnam to produce commercial feeds

Indicative Funding
$206,468 over 2 years
Summary
Developing key nutrient requirements for giant grouper in Australia for application to Australia and Vietnam. The project is based at JCU Townsville, with engagement from key stakeholders in the aquafeed industry in Vietnam through development of an Expert Working Group for dissemination and input into future research. It is aimed at developing feeds for grouper that enable smallholders to transition from `trash? fish feeding to commercially produced feeds and to support the industry in R&D dissemination, implementation and feed supply debottlenecking.

CRC for Developing Northern Australia - Grant

Improved education and training models to futureproof the aquaculture industry need for skilled staff to 2050

Indicative Funding
$128,155 over 1 year, in partnership with LMC Training Pty Ltd ($1,000) and the Fisheries Research & Development Corporation ($18,200)
Summary
By evaluating industry workforce needs currently and into the future and analysing the gaps between industry need and educational output, we aim to highlight gaps in careers pathways to meet future industry requirements. These careers pathways will form the basis of promotional tools created to highlight education and skills development options that lead secondary students into the aquaculture industry. Cost-effective delivery models for training will be key to the outcomes of the project and a pilot project to up-skill existing industry employees in biosecurity will be used to develop and de-bottleneck new training delivery models.

Grouper nutrition review

Indicative Funding
$50,272 over 1 year
Summary
A new ACIAR Concept Note is in preparation for the continuation of ACIAR investment in hybrid grouper aquaculture in Vietnam (FIS/2020/106). In parallel with the development of the Concept Note that will include a high level approach to nutrition research, a desk-top review of existing research is needed to prepare a targeted and practical research focus for the grow-out nutrition component of the project. The frequency of publication of peer-reviewed articles in grouper nutrition is ever increasing and understanding the current status of research is critical in order to maximise ACIAR investment in this area. The review will inform the detail of the experimental approach in the next ACIAR project, which needs to be planned in advance of the project start to maximise outcomes (possible start in July 2021). In addition, the COVID-19 pandemic has prevented further scoping travel to Vietnam in the short-term which will necessitate careful remote planning with proposed research partners to identify the most appropriate research systems and resource requirements in Vietnam and Australia for this research component (to be considered in time for resource requirements to be included in the Concept Note submitted in June 2019).

Tarac Technologies Pty Ltd - Contract Research

Acti-meal dose-response for abalone.

Indicative Funding
$59,500 over 1 year
Summary
Tarac international wish to evaluate their grape marc commercially marketed as `Acti-Meal?. This has shown positive effects on growth for greenlip abalone. Marketing this product needs further validation and examination of mode-of-action, which we hope to elaborate with this project. This research is expected to lead on to further contracts with Tarac, including abalone and prawn nutrition.

ACIAR Lobster Nutrition Review

Indicative Funding
$35,490 over 1 year
Summary
A new ACIAR scoping project is being prepared in support of possible new ACIAR investment in tropical rock lobster (Panulirus homarus and Panulirus ornatus) aquaculture in Indonesia. A thorough review of literature is proposed in order to prepare for the nutrition and feeds development component of the project, ensuring that we apply the learnings from previous projects and current scientific literature. The review will inform the detail of the experimental approach in a proposed new ACIAR project, which will benefit from advanced planning prior to the project start to maximise outcomes (possible start in July 2021). In addition, the COVID-19 pandemic has prevented any scoping travel to Indonesia in the short-term, providing opportunity to complete a review and facilitating best use of resources once the project starts.
