Closed Fish farming


The Closed fish farm from MMC FIRST PROCESS

Proven technology in a “new costume” - low risk to fail - great opportunity to succeed.

The crowding grids has proven a fantastic fish welfare – transported fish has a quality similar to fish swimming free in the sea. The circulation principle is based on CFD analysis and is proven in operation over many years with following UPS`s

  • Exploit the clean water in the fjords with closed tanks and flow through of sea water.
  • Crowding grid toward bottom with fish outlet in the bottom.
  • Proven gentle off-loading secure fish welfare.
  • Optional pumping and grading on board.
  • Minimal lifting height - low energy consumption.
  • Standardized modules of steel – circular tanks.
  • Partial flow collects heavy particles in filter. 
  • Sludge could be delivered to plant for drying and further processing to bio-gas or other purposes.
  • Electric power from shore – on board generators for emergency operation.
  • Smooth surfaces inside and outside for easy cleaning.
  • Autonomous unit with simple and safe mooring. 

Securing sustainable growth:

  • Max density 50 kg/m3
  • Low energy cost with propeller pumps for circulation of water (lifting height some 20 cm)
  • No land costs
  • No cost for water treatment or RAS technology
  • Autonomous operation – less crew, working boats and manual operations
  • No need for lice treatment
  • Low mortality
  • No need for wrasse fish
  • Closed containment ensure no escaping

The Closed Fish Farm from MMC FIRST PROCESS: A Revolution in Sustainable Aquaculture

In the world of aquaculture, innovation is key to addressing the growing global demand for seafood while maintaining environmental sustainability. One remarkable innovation in this field is the closed fish farm developed by MMC FIRST PROCESS. This state-of-the-art technology combines proven principles with cutting-edge design to create a low-risk, high-reward opportunity for fish farming. In this article, we will explore the key features and benefits of MMC FIRST PROCESS's closed fish farm and how it contributes to the welfare of fish, environmental sustainability, and overall operational efficiency.

Proven Technology in a "New Costume"
MMC FIRST PROCESS's closed fish farm introduces a revolutionary approach to fish farming by utilizing proven technology in a modern design. The closed fish farm minimizes the risk of failure while offering substantial opportunities for success in sustainable aquaculture. The innovation lies in its ability to create a controlled and optimized environment for fish, resulting in exceptional fish welfare and product quality.

Fish Welfare and Quality
One of the most remarkable aspects of MMC FIRST PROCESS's closed fish farm is its crowding grids, which have proven to provide exceptional fish welfare. Fish raised in these closed systems experience water quality and conditions akin to those found in the open sea. This results in fish of exceptional quality, equivalent to those swimming freely in their natural habitat. The system ensures that fish are healthy, stress-free, and free from external contaminants.

Efficient Circulation and Filtration
The circulation principle of MMC FIRST PROCESS's closed fish farm is based on Computational Fluid Dynamics (CFD) analysis, which has been fine-tuned through years of operational success. This advanced circulation system combines the use of clean fjord water with closed tanks, ensuring a constant flow of sea water through the tanks. The crowding grid, located towards the bottom of the tanks, optimizes fish density, and fish are off-loaded gently at the bottom. This design minimizes lifting height and reduces energy consumption, making it an energy-efficient and sustainable solution.

Modular and Sustainable Design

The closed fish farm consists of standardized modules made of steel, featuring circular tanks. This modular design allows for scalability, making it suitable for farms of varying sizes. Additionally, the partial flow system efficiently collects heavy particles in filters, reducing water pollution and minimizing the environmental impact of fish farming. The collected sludge can be further processed into bio-gas or other valuable resources.

Environmental Considerations
MMC FIRST PROCESS's closed fish farm places a strong emphasis on environmental sustainability. The system can be powered by electric power from shore, reducing the carbon footprint associated with on-site power generation. On-board generators are also available for emergency operation, ensuring uninterrupted fish farming operations.

Hygiene and Maintenance
The closed fish farm features smooth surfaces both inside and outside the tanks, facilitating easy cleaning and maintenance. This reduces the risk of disease outbreaks and ensures a clean and healthy environment for the fish.

Autonomous Operation and Safe Mooring
The closed fish farm is designed to operate autonomously and can be easily and safely moored. This feature enhances the farm's overall operational efficiency and reduces the need for constant human intervention.

Clean fjord farming
MMC FIRST PROCESS's closed fish farm represents a significant leap forward in sustainable aquaculture technology. By combining proven principles with innovative design, it offers a low-risk, high-reward solution for fish farming. With its focus on fish welfare, environmental sustainability, and operational efficiency, this closed fish farm is poised to revolutionize the aquaculture industry, providing high-quality seafood to meet the world's growing demand while minimizing its ecological footprint. We believe that this is the way forward to keep the fjords clean also in the future.
