Called atún de almadraba in Spanish, wild almadraba bluefin tuna refers primarily to Atlantic bluefin tuna (atún rojo in Spanish) that is caught using an ancient artisan method of fishing known as almadraba.
The method uses an intricate maze of interconnecting trap nets that lead the tuna fish to their final destination - a circular central trap surrounded by boats, where only the largest adult tuna are caught and lifted from the nets, while the smaller and younger ones are set free into the ocean, making this technique of fishing sustainable.
Starting in May, the tuna are sourced off the coastline of Cadiz Province, in the towns of Barbate, Tarifa, Conil de la Frontera, and Zahara de Los Atunes, during their migration to warmer spawning-grounds in the Mediterranean waters. The tuna is of the highest quality during this period as the blubber it has built up over the winter months results in meat that is juicy and succulent, with melting texture and an exceptionally sweet flavor.
