DownloadThere is growing interest in how to optimise the cultivation conditions for Asparagopsis spp., which are crucial for its commercial production and economic viability. However, its complex life cycle, especially the gametophyte stage, has made this challenging. Improving our understanding of cultivation conditions will enable better insights into aquaculture site selection, seasonal variation in growth and health, and optimal harvest timing for maximal bromoform concentration.
This fact sheet, developed as part of the project Developing Asparagopsis cultivation at scale for rapid industry growth, summarises the outcomes of research into how light intensity, light spectrum and temperature influence the growth rate and bromoform concentration of Aspragopsis taxiformis gametophytes in controlled conditions. Each variable has the potential to influence growth rate and bromoform concentration, but not always in the same way. Offshore seaweed producers may wish to consider these variables and their influence on growth and bromoform concentration before deciding on an aquaculture site or when they plant and harvest.
