The Need

The global demand for fish is rising by 7 million tons of fish per year, but traditional methods of catching and raising fish can't keep pace. This creates a fish source protein shortage, strains coastal ecosystems and threatens food security.

Conventional near-shore and inland aquaculture have limitations:

• Nearshore water is usually relatively stagnant with low dissolved oxygen levels causing lower fish quality and health.
• The stagnant water may create environmental pollution risks.
• Near shore fish cages disturbs the landscaping collides with  tourism, residential and other sea-view and near shore growing demands.

• Conventional fish cages cannot be placed in open sea because they cannot withstand stormy conditions.
• RAS (recirculating Aquaculture Systems, which is currently the main available solution) technology for growing fish suffer from High CAPEX and OPEX and require valuable land footprint.

The Solution

The future of this industry is large scale offshore .

Fish grow better in open sea:

• Fish grow in their natural environment.
• Excellent water quality – high quality healthy fish.
• Oceans have endless space for mariculture that can be located all over the planet.
• Minor ecological impacts. Maybe even positive impact due to growth of natural habitat.

The major challenge of  aquaculture in open sea is the weather:

• Storms, waves, currents, winds etc.
• Conventional cages do not withstand
• Neither due fish as their natural behavior is to dive deep during harsh sea conditions.

Mariculture-Systems: the Future of Sustainable Fish Farming

Mariculture-Systems' open-sea aquaculture offers a profitable and sustainable solution for large scale production of quality fish. The solution is a semi-submersible platform that can handle rough sea conditions of high waves, stormy winds and underwater currents. . During storms, the net pens holding the fish descend to 35 meters below the surface, mimicking the natural behavior of fish seeking deeper waters to get away from the stormy effected waters. This innovative system allows for year-round operation in harsh conditions,  a leading solution that eventually will be one of the future solutions replacing inferior traditional methods.

Ensuring Food Security through Sustainable Fish Farming

The company's offshore farms will integrate into the forefront of the fish farm industry creating a path for growth for major production players, which are currently suffering from many obstacles.

This method also minimizes the impact on coastal ecosystems typically stressed by conventional fish farms.

In Addition, these innovative platforms utilize clean, renewable energy sources like solar panels to power operations. Furthermore, the platform design itself fosters a healthy marine environment. By creating protected zones around the farm, Mariculture Systems may fosters the growth of marine life, promoting biodiversity and a thriving habitat.

The large-scale production capacity (7,000-10,000 tons of fish annually) is a system that enables major industry players to rapidly increase production and supports meeting the growing global demand for protein-rich seafood, insuring global and national food security and independence.

Mariculture-Systems pioneering method optimizes the growth of fish, by enabling a healthy and efficient living environment, while using state of the art AI based fish growth control algorithms and maintaining principles of ecological sustainability. The principal aim of Mariculture-Systems is to promote to the next level the required aquaculture industry demand for open sea off-shore aquaculture, while changing the aquaculture landscape, delivering a solution which enables unparalleled sustainability and remarkable profitability.

The Product and Technology

The product is a semi-submersible rig from which a universal net pen system is hung.

This universal net pen (cages) structure can be adopted to grow different fish species.

The Rig leans on the engineering development of the oil industry in recent decades enabling solutions that can withstand rough sea conditions.

The operating principle is that during storms, the net pens are lowered from the sea surface down to a depth of 35 meters below sea level. This allows the fish to exhibit their natural behavior of diving deeper during storms. This principle (and others) is protected by two patents registered in 35 countries. Those solutions were already implemented in different methods of operations and therefore are proven to fully function.

Both in the upper nets pen mode in calm seas and in the lower mode in rough seas, automatic feeding of the fish continues, monitored, and controlled by integrated video and acoustic systems with AI continuous improving performance of the fish growth. 

Due to the scale of operation in each platform, it enables implementing the most advanced solutions for feeding, AI algorithms, monitoring, cleaning and all other aspects of industrial automated factory.

Key features of their solution include:

Specious versatility: The universal net pen system can be adjusted to accommodate various fish species and sizes, from relatively small fish like seabream and sea bass, thru medium size fish like yellowtail and Salmon up to very large Tunas.

Harsh Sea Condition Tolerance: The semi-submersible rig can withstand harsh sea conditions, including waves up to 17 meters high. This allows for fish farming in open sea locations where traditional methods would be impractical or impossible.

Storm Resilience: During storms, the net pens are lowered to a depth of about 35 meters, allowing the fish to exhibit natural diving behavior. This reduces stress on the fish and a prevents mortality.

AI optimization: The system includes AI algorithms for feeding and growth optimization. Integrated video and acoustic systems monitor and control feeding, ensuring optimal growth rates and minimizing waste.

Sustainability: Fish have significantly lower carbon emissions compared to other animal protein sources, with emissions typically ranging from 10% to 15% when compared to beef. In addition to this, open-sea fish farming does not require land or freshwater resources. By incorporating off-grid alternative power sources, the CORALIS platform serves as a sustainable fish factory that plays a significant role in mitigating global warming.
