The Berdel Eguna (Day of the Mackerel) is an initiative promoted more than a decade ago by the San Pedro Fishermen’s Guild and its main objective is to promote and disseminate the qualities of this species of fish, the mackerel.

In 1993, and as a result of a process of reflection, the Day of the Mackerel was born as a boost to the fishing sector of our coasts.

Since then, this day has been celebrated annually and unquestionably the mackerel has become linked to the town of Mutriku. Local chefs and those from the surrounding area prepare different recipes using this type of fish, which is offered to visitors who come to the port in the form of pintxos, among others.

In Mutriku, both in the restaurants and in the establishments, the quality product is the protagonist. The organisation of this popular festival would not be possible if it were not for the voluntary work of the local people, who work tirelessly and unselfishly during the week before and during the big day so that the participants in the festival can enjoy it.



The mackerel is an oily fish similar in size to the txitxarro, which takes its name from its characteristic greenish back. It is a fish that is very beneficial for health, as it has high levels of protein and polyunsaturated fatty acids.

This festival has become one of the most popular in Mutriku, with the whole town taking part, with more than 20,000 pintxos being handed out every year. It is traditionally eaten roasted, but the versatility of mackerel means that it can be prepared and eaten in a many different ways.
