“Our mission is to offer fresh and sustainable char to restaurants and folks in Montreal.”

Opercule is the first urban fish farm in Quebec

NP: Opercule is the first urban fish farm in Quebec, and in doing so, we are allowed to create direct links with restaurateurs and consumers. By using a recirculating system and starting with certified eggs, we can raise without antibiotics, hormones or medicine.

DDC: Opercule is an Arctic char fish farm located in the Ahuntsic district of Montreal. We raise it using a filtration system that allows us to use 200 times less water than in traditional fish farming.

Traceability assured, delivered by electric vehicle

NP: As we deliver directly to restaurateurs, all quality, traceability and freshness issues are kept to a minimum. With the recirculation system, we are allowed to control the rearing parameters so that the fish are in the best possible condition.

DDC: Our uniqueness comes from the location of the project. We produce in the city, close to consumers and we deliver by electric vehicle.

How would you describe Opercule Char?

DDC: As the freshest char in town! It is a salmonid, so the flesh is orange-pink, relatively fatty and rather firm.

NP: It is a fish that was raised locally, the freshest. It is in the same family as salmon, but it has a more delicate, more refined taste.

Ocean Wise Seafood – so much more than a just logo

DDC: What surprised me the most about the partnership with Ocean Wise is precisely the fact that it is not a certification, but a partnership. Ocean Wise gives us visibility, credibility and gives us access to a whole network in the food industry. Basically, we were expecting a logo, but it’s so much more than that.

NP: We contacted Ocean Wise to show that we wanted to farm responsibly, so that our customers could consume our product with peace of mind knowing that they were making a responsible choice. But with the partnership, we are able to do much more, we have access to a network with the same long-term vision.

Taste with intent – support the sustainable movement

SDC: To support us, all you need to do is go to the restaurants that serve our fish or buy some in grocery stores.

NP: You can also follow us on Instagram for the latest news and to find out where you can taste our char.

Together, we have the power to drive the sustainable seafood movement with simple, everyday choices.
