Our Fish
Atlantic Bluefin Tuna
Thunnus thynnus
Wild Atlantic bluefin tuna from the Croatian Adriatic is the core of what BLUE FINESSE offers: each wild fish is individually caught, handled and documented, from catch to delivery. For buyers who need planned volumes, we also offer selected farmed Adriatic bluefin.
Croatian Adriatic origin
Wild bluefin is sourced from the Croatian Adriatic through licensed local fishermen.
Wild, individual catch
Caught one fish at a time by hook and line, each with its own catch story.
Ikejime handling
Stilled immediately using the Ikejime method to protect texture and quality.
Careful cold chain
Chilled without delay and kept within a controlled cold chain through to delivery.
Traceability
Every bluefin tuna shipment is accompanied by a delivery note and the relevant ICCAT/eBCD traceability documentation.
Professional processing
Processed and packed through approved professional partner facilities.

Why wild
Caught in the Croatian Adriatic.
Wild Adriatic bluefin lives and feeds in the open sea, taking the prey that the season and the area offer. Every wild fish develops differently, so fat distribution, texture and flavour vary from one catch to the next.
Wild bluefin is valued for its naturally deep-red flesh and typically leaner profile, with less fat than farmed bluefin. Colour, fat and marbling still vary with the individual fish, season and cut, and the two sourcing profiles serve different culinary needs.

- A catch story
Wild availability follows the Adriatic. The sea, the season and the legal fishing framework decide what we have. For planned, recurring volumes, see selected Adriatic bluefin.
Sourcing
Two routes, chosen on the same principles.
Wild Adriatic bluefin is seasonal and tied to a specific catch. For buyers who need planned volumes and defined specifications, selected farmed Adriatic bluefin is a different route, with a managed feeding programme and Ikejime harvest.
Both routes are supplied in two distinct formats:
- Fresh whole fish
- Gilled & gutted (G&G), supplied fresh and chilled.
- Cuts and fillets
- Vacuum-packed and superfrozen at −60 °C.
Formats and availability depend on the route and the season. Both routes follow the same principles: known origin and careful handling. Every bluefin tuna shipment is accompanied by a delivery note and the relevant ICCAT/eBCD traceability documentation.
Nutritional profile
What bluefin naturally contains.
Atlantic bluefin tuna naturally contains a range of important nutrients, including protein, omega-3 fatty acids, vitamin B12 and selenium.
Exact nutritional values vary naturally depending on the individual fish, cut, fat distribution, season and preparation.
- Protein
- A natural component of tuna muscle.
- Omega-3 fatty acids
- Naturally occurring marine fatty acids, with levels varying between cuts and individual fish.
- Vitamin B12
- Naturally present in tuna.
- Selenium
- A naturally occurring trace mineral found in tuna.
The Adriatic
The sea behind the fish.
The Adriatic is part of the Mediterranean Sea, known for its clear waters and a distinctive marine environment, often regarded as among the cleaner parts of the Mediterranean. The character of the sea, its open water and its seasons all form part of the story behind our Adriatic fish.
The fish begins in a real place. The Adriatic is not just a point on a label. It is the environment that shapes each fish’s story, and the starting point of the traceability behind every Fish Passport.



Beyond the QR code
Traceability & standards
Fish Passport is the customer-facing layer of our traceability. Behind it sits the professional documentation and handling framework required throughout the supply chain.
ICCAT / eBCD
Every bluefin tuna shipment is accompanied by a delivery note and the relevant ICCAT / eBCD traceability documentation, and moves through the professional EU seafood supply chain. This official documentation is separate from Fish Passport, which is our own customer-facing record of an individual fish's story and does not replace it.
HACCP
Processing and packing take place in approved professional partner facilities working under HACCP-based food-safety procedures.
Ikejime
Each wild fish is caught individually by hook and line, then stilled using the Ikejime method. It is rapid, controlled handling immediately after capture that preserves the texture, colour and quality of the flesh.

Our wild Adriatic bluefin tuna carries the “Fish from Croatia” mark, the Croatian Chamber of Economy's national origin and quality programme for Croatian fishery and aquaculture products.
We work directly with licensed Croatian fishermen and selected professional partners. Individual certificates and handling standards are linked to the relevant fisherman, vessel or partner where applicable.
