Résumé du contexte et des objectifs généraux du projet

The ASPIRE project was developed in response to the growing need for sustainable aquaculture practices and the untapped potential of seaweed farming as a solution to environmental and economic challenges. As global demands for sustainable protein sources and climate-smart farming practices increase, seaweed cultivation offers a promising pathway to address nutrient pollution, improve coastal water quality, and contribute to carbon sequestration. However, limitations in knowledge about optimal strains, cultivation techniques, and scalable practices have hindered its full potential.

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.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

The ASPIRE project undertook a comprehensive approach to advancing the cultivation and utilization of the red seaweed Palmaria palmata. The primary technical achievements include the establishment of a diverse collection of Palmaria strains sourced from multiple North Atlantic locations, enabling robust phenotypic and biochemical assessments. Using a remodeled High-Throughput Phenotyping Platform (HTPP) at the University of Galway, over 70 strains were evaluated for growth performance, protein content, and metabolic profiles. These insights informed the selection of elite strains with high yield and nutritional potential.

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.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

The ASPIRE project delivered several groundbreaking results that push the boundaries of current knowledge and practice in the cultivation and utilization of Palmaria palmata. Notably, the successful assembly of the first draft genome of Palmaria palmata is a major milestone, offering unprecedented insights into the genetic basis of desirable traits such as high protein content and growth efficiency. This genetic framework not only enhances our ability to select and breed high-performing strains but also supports future research in molecular breeding and biotechnology applications.

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.
