See how Vulkan fish transforms your plate from a fish in the sea to a beautifully crafted plate

When you grab a bite at Vulkanfisk in Mathallen Oslo, you're not just enjoying fresh, delicious seafood – you're supporting sustainable fishing practices that protect our oceans. But what does "sustainable seafood" actually mean, and why do we care so much about it?
What Makes Seafood Sustainable?
Sustainable seafood is all about protecting ocean resources for future generations. It means the fish we serve comes from well-managed populations, is caught or farmed using methods that minimize environmental impact, and supports the livelihoods of fishing communities.
At Vulkanfisk, we take this seriously. Norway has some of the strictest fishing regulations in the world, and we're proud to work with suppliers who share our commitment to ocean health.
Our Sourcing Philosophy
Every morning, we carefully select our seafood based on three key principles:
Seasonality matters. Just like vegetables, fish have seasons when they're at their best. We follow Norway's natural fishing cycles, which means our menu changes throughout the year. Winter brings excellent cod and haddock, while summer is perfect for mackerel and prawns.
Local whenever possible. Norway's coastline stretches over 100,000 kilometers, giving us access to some of the world's best seafood right in our backyard. We prioritize Norwegian fish and work with suppliers along the coast who practice responsible fishing.
Traceability is key. We know exactly where our fish comes from – which waters, which vessel, and when it was caught. This transparency isn't just good practice; it's essential for ensuring quality and sustainability.
What You'll Find on Our Menu
Visit Vulkanfisk and you'll notice we focus on species that are abundant and responsibly managed. Our famous fish and chips features MSC-certified cod, our seafood soup is packed with sustainable Norwegian shellfish, and our seasonal specials highlight underutilized species that deserve more attention.
We're also not afraid to get creative. Sometimes the most sustainable choice is the fish people overlook. That delicious mackerel sandwich? Mackerel is one of Norway's most abundant and sustainable fish species, packed with omega-3s and absolutely delicious when prepared fresh.
Small Choices, Big Impact
Every time you choose sustainable seafood, you're voting with your wallet for healthy oceans. At Vulkanfisk, we believe great food and environmental responsibility go hand in hand. After all, we want to serve amazing seafood not just today, but for decades to come.
Next time you're at Mathallen, stop by and ask us about the catch of the day. We love talking about where our fish comes from – and we think you'll taste the difference that fresh, sustainable seafood makes.
