Microboost: Microalgae Solutions to Advance Aquaculture

 Seagriculture EU 2024

Fish feed pellets from Sparos

The Microboost project, a pioneering initiative funded by EEA Grants Blue Growth Programme, has reached its final stage. Led by Allmicroalgae and involving key partners from Portugal and Norway, the project has taken significant steps in using microalgae to enhance fish health and resilience in aquaculture.

Project overview

Microboost was launched to develop and optimize microalgae-based functional aquafeed ingredients to improve fish health and cultivation productivity, crucial elements for sustainable aquaculture practices.

Over the past two years, the project team has conducted extensive research and development, creating high value immunostimulatory ingredients derived from Nannochloropsis sp. and Euglena gracilis.

These efforts were supported by the advanced facilities of the Norwegian Institute for Water Research (NIVA) and the University of Bergen, along with Portugal’s Marine and Environmental Research Centre (CIIMAR), GreenCoLab, and the company Sparos.

Key achievements

  • Strain Optimization and Scale-Up: Selection and optimization of microalgae strains from NORCCA, the Norwegian Culture Collection of Algae, have been completed, with significant enhancements in growth performance and biomass production.
  • Biorefinery Development: The project has successfully established protocols for cell disruption and biomass processing, facilitating the extraction and purification of valuable bioactive compounds.
  • Bioactivity Validation: Through rigorous in vitro and in vivo testing, the project has confirmed the health benefits of microalgae-derived ingredients, demonstrating their potential to boost immune responses and overall robustness in fish.
  • Product Formulation and Commercialization: Pilot products have been formulated, to meet the industry’s high standards and pave the way for commercial launch. The project anticipates the introduction of these ingredients into the aquafeed market, significantly impacting the sector’s growth and sustainability.

The future…

As Microboost moves towards its conclusion, the focus will shift towards market introduction, where the results of this research are expected to contribute significantly to the aquaculture sector. According to Alexandre Rodrigues, Coordinator of Allmicroalgae’s Innovation Department, “The continued collaboration among the project’s partners will ensure that the advancements made will have a lasting impact on the industry and beyond.”
