Lamorna Ash talks about her book Dark, Salt, Clear with EconTalk host Russ Roberts. Ash leaves London and moves to the small fishing village of Newlyn, near where her mother grew up on the Cornish coast. In Newlyn, everything revolves around fishing. Ash gets herself a bunk on a trawler and quickly learns how to gut fish with sharp knives on a rocking boat in the middle of the night. And so much more.
