Sea Harmony’s ORTO Technology, with its main model Pisa Reef, solves this problem by moving the production process always a few meters below the surface, where it is protected from the destructive energy of the waves. This overcomes the most common risks associated with conventional technologies: storms and other extreme meteorological conditions, surface icing, pollution and marine vessels’ collisions.

Aquaculture impact

ORTO turns the environmental problem of rising eutrophication and bottom destruction into an effectively unlimited and free resource of food.

  • This storm-resistant capability allows going out of the bays utilizing the open sea shelf up to 90m. It creates a competitive advantage to local mussel industry development.

  • Allows growing integrated aquacultures: mussels, shrimps, snails, crabs and fish

  • Extensive aquacultures: does not require any “spat” materials, animal feed, fresh water, food or medical supplements

Environmental impact

  • Mimics the natural conditions of coral reefs creating an environment for breeding and restoration of marine populations of the varieties of species in the food chain: mussels, shrimps, crabs, sea snails, fish.

  • Relieves the ecosystem from extra organics by providing mussels and co-species to be harvested. This turns ORTO into a powerful natural anti-eutrophication “Dead Zones”

  • Creates a marine protected area from overfishing, bottom trawling and other unsustainable practices.

  • Improves and sustains water transparency, reviving the macro-algae.

  • Mussels’ production has an extremely low carbon footprint. Natural carbon mineralization in the mussel shell. 1 Pisa Reef module absorbs 1373kg CO2/yr. (164t CO2/yr. per 120 Pisa Reef modules), making 1ha of ORTO area = 1ha forest.

  • Greenhouse effective animal protein production: Mussel production is associated with 400 hundred times less carbon than the beef meat production – not requiring any animal feed, fresh water or fertilizers.

  • Mussels clean nitrogen and pollution from the water, reducing emissions of nitrogen oxide, a potent greenhouse gas. Mussel protein does not emit N and P, like beef, pork, chicken and fish.

  • Shellfish are an alternative source of protein to meat, lower in fat, easier to digest.

  • Non-market size mussels are an effective animal feed resource and mineral supplement (Ca and microelements) for farmed animals and pets

  • Reverse soil nutrients cycle – mussel shells are rich on microelements (N, P) – base for producing natural mineral soil fertilizer

  • Shells are a proven eco-friendly construction material.

  • Highest Artificial Reef impact – maximum water layers efficiency

  • Artificial sound reduction effect.

  • Coastal erosion defence by decreasing the wave abrasion

  • Pisa Reefs replace all synthetic fibre ropes and do not emit micro plastics.

  • Designed to be 100 % recycled and can be constructed with recycled materials

Food security impact

One way to meet growing seafood demand while minimally impacting the environment is to expand the extensive aquaculture.

Reef farms produce high-quality animal protein independent from extreme weather conditions like droughts, floods, frost, hail, fires, temperature peaks, etc. Reef Mussel Farming is barely the third business activity in the known human history (alongside with Beekeeping and Marine macroalgae) that has reviving effect and gives more to the Nature than it takes!
