The oceans cover more than 70 percent of the earth but only two to three percent of the global food production comes from the oceans. Still, the oceans are dramatically overfished with more than 100 million tons of fish consumed worldwide, which is more than the fish population can produce.

In order to produce sufficient animal protein from seafood in a sustainable way, aquaculture is becoming increasingly important. According to the United Nations, world population is projected to reach 8.5 billion in 2030, increasing further to 9.7 billion in 2050 and 11.2 billion by 2100, which puts even further pressure on global food security.

In many countries, consumers increasingly demand healthy food from healthy animals as sustainable production methods, traceability and animal welfare are becoming competitive factors.

About one third of global fish stocks are considered to be overfished and the growing demand for healthy food, such as salmon that provides omega-3 fatty acids, requires alternative production methods.

Demands for healthy, high-quality food are not only coming from consumers but from authorities as well, as food safety regulations are putting increasing pressure on producers of animal protein.

Electrification, automation and digitalisation support in aquaculture

Aquaculture is becoming increasingly important for global food production. In order to ensure sustainable protein production, modern technology helps to improve energy efficiency, plant availability, product quality and overall productivity.

With focus on the environment in the calm fjords as well as securing the fish health, the government and the farmers realised the necessary of building large and secured ocean aquaculture farms to be located in rough water.

Norwegian company Nordlaks is building the 385 metre long and nearly 60 metre wide Havfarm 1 in the Norwegian sea. The sea farm will operate in more exposed waters than is common in today's aquaculture industry. After completion, Nordlaks plans to add a 7.5 kilometer power cable with a capacity of 3.5 megawatts to the sea farm so that it is supplied with clean energy from land.

Nordlaks chose Siemens as the technology partner for automation with Simatic S7-1500 and the Totally Integrated Automation Portal (TIA Portal), network products for production platform and administration platform, Sinamics G150 drives, transformers, and generators.

Raisioagro is shipping fish feed to fish farms across Finland as well as in Russia and must meet the high quality requirements set by its customers. To ensure stable product quality, continuous monitoring of the production process is required.

Collecting data from all areas

In order to trace any potential quality defects and to respond appropriately to any complaints from customers, Raisioagro needs to collect data from every production batch. The available process data was found to be scattered in various distributed locations with a lack of centralised management and utilisation.

With the help of Siemens, Raisioagro managed to establish a connectivity and data management solution that could be easily integrated with all the existing automation systems as well as with new equipment in the future.

MindSphere, the open Industrial IoT operating system from Siemens, was the best match to answer these requirements. As a result, product quality has already been improved with the knowledge derived from collected and visualised data.

The future of fish farming

The first Aquaculture 4.0 closed-containment system for tropical fish was built by Singapore Aquaculture Technologies (SAT), using automation and IoT technologies from Siemens for efficient and secure operation.

The offshore farm with 3,000 square metres is located off Pasir Ris Coast in Singapore. It uses a Recirculating Aquaculture System (RAS), making it the first known Aquaculture 4.0 floating closed-containment fish farm. It creates a controlled environment through a multi-level water treatment process.

In addition, the farm integrates a high degree of automation, self-regulated control cycles and artificial intelligence within a farm management information system to achieve a productive and environmentally friendly operation.

Siemens provided automation systems for increased productivity including MindSphere for cloud connectivity and data analytics, process instrumentation for monitoring and video analytics based on artificial intelligence to optimise feeding.

Solutions that cover the entire aquaculture value chain

Siemens delivers products and solutions for an efficient, secured and future-oriented production for all parts of the value chain, which is demanding specific solutions that support every relevant aspect. Siemens brings to the table long-standing experience and solutions for fish feed production as well the required equipment for providing a sustainable environment for fish production.

This enables aquaculture companies to optimally measure water parameters, flow, level, pressure, and weight. By integrating cutting-edge technologies like artificial intelligence, edge computing and blockchain, companies can continuously optimise their operation.

Combined land and sea-based farming

The traditional and cost-effective method combines the land-based farming of smolt and the sea-based rearing of adult fish.

Land-based fish farming will reduce the production time thanks to the possibility of controlling the temperature and the light in the cages. In addition, this is a possibility for the industry to avoid escape and reduce diseases.

Perfect match with customer needs

Products and solutions for the aquaculture industry are not one-size-fits-all. With the co-creation approach from Siemens, the solutions match the specific requirements of each company.

'The most important thing for us is to obtain relevant information from the production process in order to improve control. Access to this new information helps us increase the consistency of product quality by reducing the quality variance between production batches,' says Petri Elonen, quality engineer at Raisioagro.

Singapore Aquaculture Technologies (SAT), a pioneer in utilising closed containment systems for tropical fish, launches its commercial Smart Floating Fish Farm at a ceremony officiated by Minister for the Environment and Water Resources Mr Masagos Zulkifli.

The 3000 square meter offshore farm, located off Pasir Ris Coast, is the first known Aquaculture 4.0 floating closed containment fish farm using a Recirculating Aquaculture System (RAS).

It creates a controlled environment through a multi-level water treatment process. In addition, the farm integrates a high degree of automation, self-regulated control cycles and artificial intelligence within a farm management information system to achieve a productive and environmentally friendly operation.

SAT has been using closed containment systems since 2012, which means the water where fish are kept are separated from sea water. This allows the farm to have more control of environmental factors that may harm the fish, such as pathogens, algae blooms, oil spills and effects of climate change.
