Bluefin tuna of la Cala Food and drink · l'Ametlla de Mar, Baix Ebre, Tarragona Image of l'Ametlla de Mar, not of the place itself. The local fleet was the first of the Principat devoted to tuna and the town is today a benchmark for Mediterranean bluefin tuna, with fattening installations off the coast. It is served raw, seared on the griddle or in the port's seafarers' stews. Photo: Hans Hillewaert (CC BY-SA 3.0) What to see and do in l'Ametlla de Mar
