Blue, or aquatic, foods hold support diets that are healthy, sustainable, inclusive, and climate-resilient. Here, Per Karlsson prepares to serve up Swedish treats from the sea. — Photo: Sabine Glaubitz/dpa-tmn

Lars Marstone is leaning on the pier in Lysekil's harbour, arms crossed, as though personally greeting the wind and waves. Moored nearby is Signe, his lovingly restored wooden boat. Her name derives from the Old Norse "Signý," meaning "victorious" or "blessed."

For more than 50 years, Signe has been braving the waves. Today she'll be taking us on an oyster and mussel tour, the first leg of our expedition to some of Sweden's "blue food" hot spots.
