The orcas doing this are tuna eaters, and we are depleting the tuna population. Barbate is very close to my hometown. Tuna was captured in the area since Roman times: https://en.wikipedia.org/wiki/Baelo_Claudia https://en.wikipedia.org/wiki/Baelo_Claudia My father's family used to work in Sancti Petri, a village created around the almadraba, then closed half a century ago. https://en.wikipedia.org/wiki/Almadraba https://en.wikipedia.org/wiki/Almadraba Why did it close? Competence from japanese factory boats. Tuna was captured in deep sea before they coasted north. I believe Barbate still has one. Another explanation in local news is that orcas get mad with the sound of motors and propellers. The nearby straight bears very heavy traffic.
