Bluefin Tuna

OSF bluefin tuna (Thunnus thynnus) is mainly raised on Mediterranean farms off the coast of Malta. The fingerlings are raised in our hatchery in Qajjenza Bay for a few months. Then, they are transferred to the offshore rearing site at Munxar Reef.

During the seasons when it is allowed to be caught, we also have wild Bluefin Tuna (Thunnus Thynnus).

Our bluefin tuna is distributed and marketed worldwide, both fresh and frozen at -60ºC, making tuna available all year round.

Tuna slaughter process - ikejime

Our professional divers enter the water and use a Japanese technique called Ikejime.

This sacrificial technique avoids the stress at the time of its slaughter and also ensures the conservation of the gastronomic quality that characterizes the Bluefin tuna.
