Mark, if you can buy fresh herrings in Spain, why not take a barbecue with a lid to the beach and hot smoke some there for immediate use, or there must be smokeries in Barcelona that you could take a variety of fish to cold smoke them over 24 hours? 😉
Maybe some good news for you Mark, apparently arenque ahumados are the Spanish equivalent, and I saw on British Expats some posts from 2011 which said Mercadona sells them frozen, so maybe stores like El Corte Ingles might too, in Barcelona? You could be eating kippers by this time next week 😉 😛
