Unlocking the Power of Algae

As the global demand for responsibly farmed seafood continues to rise, the need for sustainable, efficient and ethical solutions in aquaculture has never been more pressing. Mersea Farming’s algae business offers a pioneering and holistic approach to meeting these challenges, one that delivers both practical benefits and far-reaching positive impact.

Incorporating algae into aquaculture systems underpins healthier, more productive operations:

• Enhanced Nutrition: Algae are a natural, highly nutritious feed source for fish, shellfish and other farmed aquatic species. Packed with essential proteins, omega-3 fatty acids, vitamins and minerals, algae-based feeds improve growth rates, bolster immune systems and help achieve superior product quality. All while reducing reliance on unsustainable fishmeal and soya.

• Improved Water Quality: Algae play a vital role in maintaining optimal water conditions. Through their natural uptake of nitrogen, phosphorus and other nutrients, algae help control waste build-up and prevent harmful blooms, fostering a more balanced and resilient aquatic environment.

• Natural Disease Resistance: Many algae species possess bioactive compounds with antibacterial and immunostimulant properties that strengthen disease resistance in farmed stock. This reduces the need for antibiotics and chemical treatments, supporting both animal welfare and cleaner production systems.

• Closed-Loop Sustainability: Algae integration enables circular resource flows within aquaculture: waste from fish or shellfish farms becomes nutrients for algae cultivation, while harvested algae are returned to the system as feed or bioactive supplements. This creates a closed-loop, low-impact model that champions both efficiency and sustainability.

Beyond the technical advantages, partnering with Mersea Farming reflects a commitment to ocean health, community empowerment and ethical farming:

• Marine Ecosystem Restoration: Our regenerative practices improve water quality and habitat diversity, supporting the recovery of degraded marine environments.

• Job Creation and Social Inclusion: Mersea Farming’s operations are structured to train and employ vulnerable and marginalised groups, opening meaningful pathways to economic resilience within coastal communities.

• An Inclusive, Regenerative Model: We believe in a future where productive aquaculture and ecological restoration go hand in hand. Creating value for business, society and our oceans.

By integrating algae through Mersea Farming, aquaculture businesses and their partners can drive operational excellence and be part of a visionary model for ethical, resilient and regenerative ocean farming. Together, we can nourish the world, without compromising the health of our seas or our communities.
