Fish feed in aquaculture is at the center of a complicated global story that most people never hear about. In this episode, Andrew sits down with marine biologist and policy expert Marine Cusa to explore the hidden world of fishmeal, fish oil, feed ingredients, and the surprising connections between aquaculture, wild fisheries, West African communities, and even penguin populations in Antarctica.
Marine breaks down what actually goes into the pellets fed to farmed fish, why transparency is lacking in the supply chain, and how her genetics research is uncovering the real species being used in fish feed. The conversation reveals why feed matters for sustainability, human nutrition, local livelihoods, and the future of aquaculture as demand for seafood continues to grow. Whether you're new to the topic or already deep in fisheries science, this episode opens the door to a critical but overlooked part of marine conservation.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
