Project number: 2023-188
Project Status:

Need

This project seeks to improve process efficiencies in inoculum production systems in hatcheries and mass culture grow out systems in land-based seaweed aquaculture facilities through selection of light sources with the appropriate spectral qualities and intensities as well as efficient carbon delivery and mixing systems. Laboratory scale optimisation trials on tetrasporophytes of A. armata and A. taxiformis will be validated under scaled-up industrial scale systems. The project proposes to trial various commercially available light sources as well as carbon delivery systems that the industry could adopt.

Objectives

1. Comprehensive review of spectral quality and intensity of photosynthetically active radiation (PAR), carbon delivery and mixing in high density mass cultures of the tetrasporophytes of Asparagopsis
2. Validated spectral quality and irradiance in high density tetrasporophyte cultures of A. armata and A. taxiformis
3. Developed optimised carbon delivery and mixing systems in tetrasporophyte mass cultures
4. Laboratory-scale trials validated under scale-up conditions.

Development and ongoing Maintenance of an Australian Standard for aquatic plant names

Project number: 2017-212
Project Status:

Need

This standard will define the standard names for aquatic plant names including algae, microalgae, samphire, etc to be used in Australia; and specify when standard names are to be used. Annex A of the standard will provide a list of agreed standard names for aquatic plants and will form part of the standard.

Plants from marine and freshwater environments are covered by this standard, irrespective of the country of origin.

The scope of the standard is intentionally broad, but the species to be considered initially for inclusion in the Australian Standard for aquatic plant names will be limited to edible marine algae, microalgae, and samphire from marine environments but species from freshwater environments can be included as necessary.

Other commercial species may be added at a later time as necessary.

Not developing a standard would result in marketplace confusion.

This project is to get the process rolling and develop an initial standard.

The project will also include the maintenance of the proposed standard for the first three years

Objectives

1. To assign standard names for current and potential edible aquatic plant names that are sold for human consumption – including commercially important algae and samphire species.
2. To achieve stakeholder support for the proposed names
3. To develop an appropriate Australian Standard for aquatic plant names incorporating the agreed list of edible marine algae.
4. To maintain the Australian Standard for Aquatic Plant Names for 3 years

Summary

This project has started as a concept and has culminated in the publishing of AS 5301- the Australian Standard for Aquatic Plant Names. This is recognised as being a “world’s first” and has resulted in an industry agreed list of names at the start of this highly important developing industry.
