In Nacional, a group known as Los ranas plays a significant role in the sea. They are referred to as 'vaqueros' of the ocean, navigating through large fish to obtain high-quality atún rojo. Their work is connected to the almadraba, a centuries-old fishing technique.

This method is used to catch wild atunes rojos that pass through Barbate annually. Further information about Los ranas and their involvement in the almadraba can be found in El Mundo, which provides more details about this unique group and their activities.
