Opercule Urban Fish Farm
The Opercule Fish Farm project is a pioneering initiative in the heart of Montreal, representing the first urban fish farm in Canada. This innovative project is based on a unique approach to fresh fish production, combining cutting-edge technology, respect for the environment and a local supply network.
Opercule annually raises 25 to 30 tonnes of Arctic Char, a fish species highly prized by Montreal restaurants and residents, and raised without the use of chemicals, hormones or antibiotics.
The primary goal for the Opercule Fish Farm was to create an eco-friendly, sustainable fish farm with a low impact on the environment and providing excellent living conditions for fish. HH Angus worked closely with the client to understand their unique and ground-breaking vision and was able to design innovative solutions tailored to this one-of-a-kind project. The project’s design also stands out for its ability to produce fresh fish locally in a non-coastal city.
This model of aquatic urbanism fits perfectly into a context where demand for local, sustainable products is growing. Working with the HH Angus design and engineering team, Opercule is meeting Montreal’s appetite for Arctic Char by supplying top-quality fish while reducing the usual carbon footprint associated with transporting seafood from coastal regions.
The project's innovative design and short-supply chain production model allow Opercule to raise high-quality fish in an urban environment in response to a growing local demand for sustainable food products. Fish swimming in the morning can be on diners’ plates the same evening, frequently delivered to restaurants by e-bikes to further reduce the product’s carbon footprint.

Enabling production at scale
No design references or construction expertise existed for this pioneering enterprise, and the client placed their trust in HH Angus’ ingenuity and adaptability to deliver the vision.
The project’s key technical innovation was the development of the Recirculating Aquaculture System (RAS) system - the first of its kind in Quebec - which allows fish to be produced in a closed circuit, from egg to table.
From the outset, we worked very closely with Opercule to thoroughly understand the challenges and goals. The client had a strong vision for their new company, were deeply committed to its success, and actively involved in the project’s technical aspects. One of the owners brought a background in consulting engineering, and this made our collaboration highly productive.
Reducing environmental impact
The primary goal for Opercule was to create an eco-friendly, sustainable fish farm with a low impact on the environment and providing excellent living conditions for fish.
The RAS process is a sustainable model that significantly reduces the environmental footprint of the operation by reducing not only water but alsoenergy consumption compared to traditional aquaculture. The system minimizes the use of these precious resources, a crucial factor in an urban environment. By recovering, filtering and reusing water, the farm significantly reduces water consumption compared to traditional fish farming methods, which are often very water intensive. The system allows the company to reduce water consumption by 100 – 200 times compared to traditional systems.
In terms of waste management, Opercule uses environmentally friendly techniques to treat the organic and biological waste generated by production, helping to reduce overall environmental impact. The project also promotes use of sustainable materials for the construction and fitout of the facilities, reducing the carbon footprint of the entire system.
In addition, the absence of chemicals, hormones and antibiotics in fish production ensures no soil or water contamination. This approach helps preserve local ecosystems and eliminates the risk of pollution.
Engineering design challenges
The complexity of the Opercule project stems from a number of technical and logistical factors. The creation of an urban fish farm requires a completely unique design adapted to a dense urban environment. The design of a water recirculation system, intended to ensure the well-being of the product from the egg stage to the delivery of the fish, required the development and refinement of innovative technologies in filtration, nutrient management, and optimization of living conditions in confined environments.
Challenges included managing water quality, which is essential for fish health, as well as creating an optimal environment for rearing Arctic Char, known to be a delicate species. This challenge involved the creation of autonomous systems to maintain constant temperatures and pH levels, without the need for chemical treatments. In addition, bio-safety management was a priority to avoid contamination.
During the operational phase, it was discovered that the heat generated by the fish—even though they are cold-blooded—had been underestimated. This required adjustments to operational conditions to maintain stable water temperatures. Despite this challenge, our close collaboration with the client ensured these modifications were implemented effectively, showcasing the team’s problem-solving abilities.
