Need

This project provides the resources for SARDI to establish and operate the Temperate Research Hub for the National Hatchery Network for 18 months (until 25 March 2025) which is the stipulated grant duration.

The FRDC project will provide the funding for SARDI to engage key technical capability needed to support the Hub and establish the facilities for exclusive and continuous use for the project. SARDI will provide facilities and services for up to two ASSA employees working at this Hub for the conduct of this project.

The key components of the project include:
1. Establish facilities and equipment required for the development of the temperate hub of the National Seaweed Hatchery Network
2. Deliver a focused research program to close the life cycle, of Asparagopsis armata, with the goal of being able to produce carpospores, tetrasporophytes, tetraspores and gametophytes.
3. Develop management systems to control contamination in the Asparagopsis armata hatchery.
4. Collect and maintain a clean broodstock culture collection.
5. Develop hatchery technology and equipment needs through experimentation.
6. Contribute to the development of a Hatchery Manual and knowledge sharing and dissemination.

Objectives

1. Establish and maintain the facilities, equipment and consumables for the Temperate Research Hub relating to Asparagopsis armata.
2. Provide research capacity, including staff, for undertaking robust and repeatable hatchery, nursery production and ‘inoculum’ transport techniques for A. armata.
3. Work with the ASSA technical team to further develop hatchery and sporulation techniques and technology for A. armata, undertake further R&D to close any gaps in hatchery technology including ecophysiology to close the lifecycle of this taxa, and develop biological contamination management techniques for seed production and maintenance of a ‘clean’ broodstock culture collection for future industry use.
4. Contribute to the development of a comprehensive hatchery manual addressing wild collection to production and transport of ‘seed’ for onshore and in sea grow out based on protocols and techniques developed from R&D at the research hub for A. armata, with the aim to assist seaweed aquaculturists to be self-sufficient in developing their own hatchery for commercial scale seedstock production.
5. Contribute to the development of standard design drawings for hatchery design for A. armata, incorporating best practice biosecurity procedures to be incorporated in the manual(s).
6. Establish base performance standards for the culture of A. armata to enable others to replicate protocols established in the hatchery manual and compare their level of success.
7. Phylogenetic cataloguing of the strains of A. armata from the viewpoint of assessing strain rigor for selective breeding and biosecurity. This will be made available as a publicly accessible database.
8. Contribute to training and knowledge sharing activities (extension).
9. Contribute to necessary finance, HR, communications, and stakeholder engagement activities associated with the Temperate Research Hub.
10. Provide milestone reporting of technical and financial progress to FRDC against plans, identifying achievements and challenges, and budgets.
