Yellowfin Tuna belly fillets offer the tenderest and most delicate part of the fish. Known for its juiciness and exquisite flavor, this tuna is wild-caught, dolphin-safe, and sourced through sustainable fishing practices that respect the marine environment. Preserved in extra virgin olive oil with a touch of salt, it reflects exceptional quality and tradition from the heart of the Basque Country. Olasagasti has spent the past 125 years devoted to making traditionally-prepared canned fish.
