HIGH PRODUCTIVE CAPACITY

The vessel can produce up to 3.900 metric tons of commercial fish production

DECREASES THE RISKS OF CONVENTIONAL AQUACULTURE

Through its efficient and eco-friendly propulsion system, it monitors, seeks and follows the best water conditions for fish production, always maintaining the best levels of oxygen, temperature, pH, salinity and other important variables to maintain a high fish productivity avoiding areas of low oxygen, acidity, algae bloom, red tide and other risks affecting coastal aquaculture.

FREE ANCHORING

No need to be anchored to a particular area.
Able to move autonomously in the seas.

ABLE TO AVOID BAD WEATHER CONDITIONS

Autonomous propulsion capacity, reaching up to 4 knots, provides the ability to avoid severe weather or other adverse offshore conditions.

HIGH PERFORMANCE STRUCTURE

Designed to sustain heavy offshore operations with minimal maintenance.

LONG OPERATIONAL AUTONOMY

The 450 tons storage areas, allows up to 25 days of autonomy.
Facilities for 6 to 20 crew.

PROPERTIES AND CONFIGURATION OF FISH NETS

Copper alloy meshes prevent frequent maintenance and cleaning, do not need mesh changes between 6 to 8 years, do not need anti-predator meshes, making fish production safe and allowing offshore production.



The copper alloy meshes can be configured as 8 cages of 25.000 m3 each (115 ft. long, 104 ft. wide and 66 ft. deep) or 4 cages of 50.000 m3 each (115 ft. long, 210 ft. wide and 66 ft. deep).

AQUACULTURE WITHOUT BORDERS

Oceanic vessel for global aquaculture, the system is prepared for full autonomous operations both, coastal or offshore production, seeking the best water conditions for the fish and thus improving profitability for the producer.

THE SHIP

- 170m, 550 feet LONG, 60m, 197 feet WIDE.

Oceanic Vessel
- Supports waves up to 7 meters, 23 feet high. 3 Diesel/electric motors Engines 4000KW. Self-Position capacity reaching up to 4 knots. Can be towed by a tugboat if necessary.

Advantages
- No need to be anchored to a particular area. Seek the better water conditions for fish. Avoid Storms and bad weather. Can be taken inshore for harvesting and maintenance.

THE CAGES

- 4mm diameter Copper-Zinc alloy meshes, 4x4cm mesh hole

Configuration
- 8 cages 115 feet long x104 feet wide x 66 feet deep. Or 4 Cages 115 feet long x 210 feet wide x 66 feet deep. Can be configured in smaller cages for the earlier stages of fish

Advantages
- Anti Fouling. Structural Resistance. Predator Protection. Better Oxygenation

FISH

High capacity producing up to 3900 TON in one cycle of salmon.
Compatible with any commercial fish species like Tuna, Cobia, Amberjack.
High efficiency, below 5% of expected biological mortality.

THE OPERATION

Fully autonomous operations, crew of only 20 people 20 to 25 days of full autonomy 450 MT of fish food storage capacity Deck operations supported by 4 electro hydraulic cranes Other vessels can dock for resupply, bring new fish and to harvest Heliport for inspections and emergency operations

30% land / 70% ocean

We transform coastal and stationary aquaculture into a mobile and sustainable industry, building the bridge between the current way of doing it and what new generations wants

SUSTAINABLE MOBILE AQUACULTURE

The world is dynamic, everything is in motion and constantly changing. The technologies of the 21st century must consider these aspects to be sustainable in the long term. This has been the cornerstone of our company.

The goal of our technology is to restore mobility to the fish, move them away from the coast and take them to open water, to areas far from the accumulated problems of overconcentration, pollution, parasites, algae bloom, red tides, drops of oxygen, among many others, giving them the opportunity to live in better quality water: better for fish, for producers, for consumers and for the Planet.

Aquaculture is one of the great opportunities that the planet have to feed the growing world population efficiently and sustainably. It is not unsustainable per se, but the way we do aquaculture will make a difference.

Rodrigo Sanchez

Head of project, Off-shore aquaculture pioneer. Manager and director of technology development in copper cages.
Since 2000 has worked on the production of large tons of fish in one of the worlds largest salmon farms (AquaChile). In 2009 was hired by EcoSea Farming to develop the copper mesh technology for the large-scale production of fish and open the market for this kind of technology.
After 7 years he designed, developed, implemented and placed more than 70 rafts with copper alloy meshes (Chile, Norway, Canada, Australia and Japan) of which more than 40,000 tonnes of fish have been harvested. Winner of the Chile national prize for Innovation 2011 and the Ibero-American prize for university innovation in 2012.

Cristino Stange

Pioneer of salmon farming in Chile, started commercial activity in 1978 with Coho Salmon farming for the Japanese company Nichiro. He develops and participates in the positioning and growth of the salmon aquaculture in Chile, highlighting milestones such as the first trout breeding in March 1986, the first export of live eggs from Chile to Japan in 1992 and several developments in breeding, reproductive management, genetics, biotechnology and Infrastructure. Participates as a shareholder and director in companies related to aquaculture, development and research.
