Periodic Reporting for period 1 - ASPIRE (Accelerated Seaweed Production for Innovative and Robust seaweed aquaculture in Europe)
Reporting period: 2022-10-01 to 2024-09-30
The project aimed to bridge these gaps by focusing on the red seaweed Palmaria palmata, a high-value species with significant potential for use in food, feed, and bioproducts. ASPIRE sought to identify and cultivate elite Palmaria strains, develop innovative tools and methodologies for their sustainable farming, and establish a comprehensive database (PalMap) to guide future research and industry efforts. By combining novel seaweed phenotypin, biochemical and genetic profiling with real-world aquaculture trials, the project set out to support the growth of a robust seaweed industry.
ASPIRE’s objectives are aligned with broader political and strategic goals, including the European Green Deal and the United Nations Sustainable Development Goals, which prioritize environmental sustainability, food security, and economic development. By enhancing the scalability and sustainability of seaweed farming, the project contributes to tackling global challenges while empowering coastal communities and promoting rural development. The outcomes of ASPIRE have the potential to significantly impact both local economies and global efforts toward a greener future.
The project also initiated large-scale aquaculture trials at Mungo Murphy’s and Carna Marine Laboratory, where land-based tank systems were employed to evaluate strain performance under commercial conditions. More than 100 strains were cultivated, exceeding initial targets, and extensive comparisons between lab and farm yields were conducted to optimize cultivation practices. A key milestone was the assembly of a draft genome for Palmaria palmata, laying the groundwork for genetic-based breeding and trait optimization.
To support these advancements, the PalMap database was designed to integrate phenotypic, genetic, and biochemical data, creating a resource for industry and academia. While still under development, the database framework and data pipelines have been established to ensure future scalability and accessibility. Collectively, these achievements position Palmaria palmata as a viable candidate for sustainable aquaculture and advance the scientific understanding necessary to support its commercial adoption.
Additionally, the integration of advanced phenotypic and biochemical analysis techniques, facilitated by a remodeled High-Throughput Phenotyping Platform, enabled precise evaluation of strain variability across diverse environmental conditions. This comprehensive approach led to the identification of several elite strains with superior biochemical profiles, particularly in protein content, making them highly attractive for food and nutraceutical markets.
On the aquaculture side, the project demonstrated the viability of land-based cultivation systems for Palmaria palmata, surpassing initial targets by cultivating over 100 strains at commercial scales. These findings provide valuable insights into optimizing yield and quality under controlled conditions, reducing reliance on offshore systems and increasing scalability for industry stakeholders.
The development of the PalMap database represents a transformative step toward knowledge-sharing and decision-making in seaweed research and industry. By consolidating phenotypic, and biochemical data, PalMap promises to be a powerful tool for stakeholders aiming to identify strains suited to specific applications and environmental conditions. While the database has yet to go live, its design ensures scalability and alignment with existing resources like AlgaeBase and WORMS.
To ensure further uptake and success, key needs include expanding genetic studies to refine marker-trait associations, securing funding for full commercialization of elite strains, and fostering collaborations to integrate Palmaria palmata into established supply chains. Additionally, supportive regulatory frameworks, international partnerships, and tailored marketing strategies will be essential to unlocking the full economic and environmental potential of this seaweed in global markets.
