Interior of a RAS hall with circular rearing tanks

Advanced engineering and technology for the aquaculture of the future.

Every facility we design and build brings together energy efficiency, waste management, and RAS technology aimed at maximizing the productivity and sustainability of the process.

Running our own facilities continuously for more than 38 years has produced a refined infrastructure, designed to deliver stability, efficiency, and operational continuity on every project.

Operational traceability

Continuous recording of every variable in the production process, from the receipt of eggs to smolt delivery.

Efficient designs

Every facility is sized to optimize water and energy use, lowering operating costs without compromising the conditions the crop requires.

Control systems

We develop control systems with the technical knowledge to design them and adapt them to different production realities.

Rearing systems

We design, build, and operate RAS farming sites with a production focus, bringing together energy efficiency, control systems we develop ourselves, and sustainable waste management.

Infraestructura diseñada desde la biología del salmón.

Design driven by the production requirement.

  • The design of every project starts from the environmental and health conditions salmon need in order to grow to the highest quality standards. Those biological requirements are the technical criterion that guides every project we deliver.

Efficiency built in from the start.

  • Water efficiency, energy efficiency, and waste handling are part of the design from the outset. Every facility is developed to operate with the lowest possible resource use and the least impact on the place where it stands.

Traceability and real-time control:

Continuous monitoring of the critical rearing variables gives full visibility of the production process. Every recorded data point supports timely decisions based on real information from each site.

Control and production system:

Our control and production systems were developed from our own operating experience. They combine automated supervision, process management, and continuous variable logging, and they can be adapted to any farming site.

Continuous process improvement:

The information our systems generate makes it possible to analyze each site's production performance, find opportunities to improve, and adjust rearing conditions based on concrete, verifiable data.

The RAS cycle that keeps rearing conditions at their best.

Technology applied to sustainability

Sustainability is a design criterion on every project we deliver. We use technology that optimizes water and energy use, and we turn production waste into valuable inputs for other sectors.

Circular economy

Our operation is structured around circular-economy principles, recovering production waste and turning it into valuable inputs that go beyond the aquaculture industry.

Water treatment

Technologies aimed at improving water quality and reducing resource use.

Energy efficiency

Solutions designed to maximize operational performance and reduce energy use.

Continuous innovation

We adopt and adapt new technologies to meet the industry's present and future challenges.

The technology pillars that define every project we deliver.

Designing a more sustainable industry.

Sustainability is no longer an alternative. It is a necessity. That is why we continually implement technologies that make production more efficient, more responsible, and aligned with the industry's environmental challenges.

Technology only has value when it solves real problems.

Our operating experience lets us identify which technologies create a tangible impact on efficiency, sustainability, and operational continuity.

We believe the best engineering comes from experience. Since 1988, we have devoted our work to understanding, improving, and refining every stage of the production cycle, contributing to the sustainable development of the salmon industry.
