Jon Gower is in Aberaeron, Ceredigion, to explore how mackerel (and other fish) have shaped the people and landscape. Jon joins the pretty harbour town’s annual mackerel festival, where the humble mackerel is given thanks at the end of its season with a funeral procession, complete with wailing widows, a blessing from the local reverend Dilwyn Jones and, most years, a sunset cremation on the beach. Here, Jon meets local townsfolk to hear how fishing connects the generations far back in their families and how livelihoods, mackerel populations and the landscape of this town are changing with the climate crisis. Jon also speaks to Elinor Gwilym from the Cymdeithas Aberaeron Society, who talk about how the charming aesthetic of the town is influenced by its connection to fishing, with the colourful harbour houses originally built for sea captains.
