Production sites

Bezhin Breizh group is currently made of three production subsidiaries and a minority shareholder of the Algolesko company.

• The SCEA CREACH ANTON, at Saint Pol de Leon
• Roscoff breeding ponds
• La Meloine breeding ponds, at Plougasnou
• ALGOLESKO, at Lesconil

CREACH ANTON Greenhouses

At the heart of the Creach Anton (locality) greenhouses is the cultivation of green and red macroalgae in on-shore basins, In a recirculating seawater system (RAS system: recirculating aquaculture system *). This specific system, unique globally for algae culture, allows the production of macroalgae in quality and quantity without any waste into the natural environment.

The greenhouse currently covers 2 hectares and is made of 48 independent basins, with an expansion planned to 5 hectares for 2022. A selection of seaweed strains, carried out upstream at the Roscoff breeding ponds, enables to optimize the robustness and the levels of active molecules within the seaweed. This unique production in ultra-controlled conditions (lighting, temperature, nutrients, pH, salinity and CO2 input) orient and seasonally adjust the culture 365 days a year. The combination of varietal selection and bio-oriented cultivation makes it possible to achieve a high production yield and a homogeneous culture enriched with active ingredients. Then, the mass production carried out by vegetative growth achieve a yield of 1000 tonnes / ha / year of fresh seaweeds. On top, an automated harvesting method helps to maintain a sustained supply rate.

In order to maintain the highest quality standards, the basins are built to pharmaceutical standards. Each seawater basin is independent and allows a homogeneous unialgal culture. This secured production also protects the seaweeds against external biological and chemical pollution.

In addition to the seaweed culture, the objective at CREACH ANTON is the installation of an algae and seafood polyculture, called IMTA, Integrated Multi-Trophic Aquaculture**.

Roscoff breeding ponds (website)

With proven know-how in the storage and trading of crustaceans, molluscs, shellfish and fishes, The Roscoff breeding ponds benefits from the seawater richness of the Roscovite coast. This same seawater is used for the greenhouse cultivation at CREACH ANTON. The Roscoff breeding ponds is also specialized in fish packaging, meeting grading methods, from the most common to the most specific.

In parallel of the fishpond activity, this site will host a hatchery-nursery for seaweeds and marine animals, as well as an R&D unit. The selection of algae strains, based on the biochemical composition and according to customer demand, will be hold in the R&D unit, an applied research center. The aim will be to select the most robust strains enriched with active molecules. The hatchery-nursery will then secures and multiplies the strains of the selected macroalgae and holds an algae bank representing the biological capital of Bezhin Breizh. In order to establish an excellent quality and high yielding macroalgae culture, every piece of the value chain must be secured, from the seaweed strain to its mass production.

La Meloine breeding ponds, at Plougasnou

In addition to the important storage and fish trade activity, La Meloine breeding ponds has a processing plant with suitable process equipment. The modernized site will continue its packaging and conservation activity for various shellfish and crustaceans.

An independant building on site will be dedicated to the “algae process” allowing a first transformation of the seaweed resource (fresh salted, IQF, grinding etc.). Once harvested at the greenhouses, the seaweed might be stored and preserved at La Meloine before being marketed.

Algolesko, at Lesconil (website)

Founded in 2013, Algolesko has a large off-shore field of more than 400 hectares, off the coast of Lesconil in the southern Finistere. It is the largest seaweed production field in Europe. The seaweed culture is made on lines in a specific area classified as “Natura 2000” (french standards, meaning an area protected from pollution). The high quality of the water allows the company to produce and harvest organic brown macroalgae, Ecocert certified. The seaweed value chain is mastered from the breeding algae in the hatchery until harvest. Algolesko then transforms its production and markets it in frozen, dehydrated or fresh salted form.
