ABOUT

Ostrea Aquaculture AB

Ostrea Aquaculture was founded in 2006. We develop the knowledge and technology needed to build the future of shellfish. With a foundation in advanced hatchery science, our work spans the entire production chain from broodstock management and larval rearing to nursery and grow-out. A core part of our operations is the large-scale production of microalgae, forming the basis for controlled, high-quality feeding systems essential to successful bivalve cultivation.

OUR MISSION

Building the Future of Shellfish

We unite hatchery expertise and sustainable aquaculture to expand the production of oysters and other bivalves supporting ecosystem recovery and long-term ocean health.

WHAT WE DO AT

Ostrea Aquaculture AB

Our work has been centered on the native European flat oyster (Ostrea edulis), where we contribute to both sustainable production and ecological restoration of a species of high environmental value. Today, the primary demand for our production is juvenile Ostrea edulis (spat), supplied to restoration projects, research institutes, and public authorities primarily in Sweden, but increasingly across the European Union. Over the coming years, we expect 70–80% of our operations to remain focused on this species.

In parallel with spat production, we are actively engaged in marine restoration. In planned Swedish restoration projects, we not only produce oyster juveniles on suitable substrates, but also take responsibility for the establishment, development, and monitoring of oyster reefs. Through this, we combine hatchery production with hands-on ecosystem restoration enabling the recovery of functional marine habitats at scale.

At the same time, we continue to develop our commercial aquaculture activities. This includes hatchery production of Ostrea edulis spat for our own marine farms, as well as sales of juveniles to other growers in Sweden and across the EU. Together, these activities create multiple, complementary revenue streams spanning restoration, research supply, and commercial aquaculture.

Looking ahead, we are expanding beyond a single species. We are developing the capability to produce a broader range of bivalves, applying our expertise to support diversification in sustainable aquaculture and marine ecosystem restoration.

In addition, we are advancing new production pathways. This includes the development of trochophore larvae as a novel, high-quality feed source for aquaculture, with initial production and evaluation beginning this spring.

Shellfish play a fundamental role in marine ecosystems. By filtering water, cycling nutrients, and creating habitats, bivalves contribute directly to biodiversity and ocean health. Our role is to translate this ecological function into scalable, reliable production systems, combining scientific precision with practical application.

Our approach integrates:

  • Hatchery innovation across the full production cycle
  • Large-scale microalgae production for controlled feeding
  • Production of Ostrea edulis spat for restoration, research, and aquaculture
  • Establishment and monitoring of oyster reefs as part of marine restoration
  • Supply of juveniles to commercial growers across Sweden and the EU
  • Development of new species and applications within bivalve aquaculture
  • Through this, we support a new generation of shellfish production — strengthening marine ecosystems while enabling sustainable growth of the blue economy.
