“…Although seaweed farming is likely useful in achieving some of the sustainable development goals (zero hunger, sustainable production, and consumption), economic growth, etc.) of the United Nations but it may affect marine life (65). In addition, BECCS deployed in algal bioenergy (bicarbonate-based integrated carbon capture and algae production) can also be a low-carbon algal bioeconomy (66).…”

“…In particular, seaweed farming has been highlighted because of its potential to help fulfilling several sustainable development goals (SDGs), such as reducing hunger (SDG 2), improving water quality (SDG 6), mitigating climate change (SGD 13) and protecting the ocean (SDG 14), emphasizing the higher ecological relevance of seaweed farming 3 . It also contributes to generating positive impacts on the community towards achieving decent work and economic growth (SDG 8), industry, innovation and infrastructure (SDG 9), and life on land (SDG 15) 4 . However, seaweed's contribution to reaching gender equality (SDG 5) have been less explored.…”

Women's participation in small‐scale aquaculture is growing, but women producers remain in a disadvantaged position compared to men. Reducing gender gaps is at the core of many development programs, but little is known regarding the source of these differences. This paper investigates the main drivers of gender gaps in seaweed small‐scale aquaculture by focusing on the analysis of differences between male and women, and across a series of psychological traits. We use data from a sample of 152 seaweed producers from central‐southern Chile and perform a matching procedure to generate a balanced sample of male and female producers in the dimensions determining their performance in the sector. Our results show that female producers may exhibit more positive psychological traits such as patience and interpersonal trust. However, women's choices in seaweed farming may be incongruent with these characteristics, as expecting more immediate returns than males, and may not be able to exploit the advantages of collaboration in selling in the sector. This supports the notion that opportunity costs (e.g., other activities in the marine area) and outside options (e.g., fishing versus trade) may be one of the major drivers of gender gaps and suggests that there are barriers keeping women from exploiting their potentially advantageous individual characteristics. Results provide important insights for the design of support instruments aimed at reducing these barriers faced by women in the sector.

The development of an Australian seaweed industry may also progress the Sustainable Development Goals of the United Nations (Spillias et al 2022). However, to realise this potential, more research into the diverse Australian marine ora is necessary to determine ideal candidates for sustainable aquaculture production.…”

Exploration of Australian fucoids for aquaculture production has been limited, despite globally high regional diversity and endemism. Sargassum fusiforme (hijiki in Japanese) is amongst the most highly valued seaweeds worldwide for human consumption, but concerns about high arsenic concentrations limit importation into countries with strict safe-food regulations and standards. We investigated the temporal and small-scale spatial variation in distribution, abundance, growth (estimated by changes in length), reproduction (estimated from the number of fertile conceptacles per receptacle and/or percentage of reproductive branches) and biofouling of two Australian sargassaceous fucoids, Cystophora torulosa and Caulocystis uvifera, that show promise as low-arsenic alternatives to hijiki. Temporal variation was assessed by seasonal surveys in a single year, in which small-scale spatial variation was assessed at a single site for each species, comparing high-shore and low-shore for intertidal C. torulosa and distance from the shore for subtidal C. uvifera. For C. torulosa, no significant variation in distribution, abundance or reproduction was observed; however, growth peaked in winter. Moreover, biofouling of C. torulosa was minimal throughout the study. In contrast, significant temporal variation was observed for C. uvifera with peaks in growth and reproduction in spring, and biofouling in summer. In both species, reproductive output increased with thallus length. Whilst both species might be promising Australian hijiki analogues, the temporal and spatial consistency in reproduction and minimal biofouling may render cultivation of C. torulosa more practical for successful commercialisation than for C. uvifera. However, generality of our findings should be assessed at larger spatial and temporal scales.
