What does it mean when sea surface temperatures break records before summer even begins? In this week’s episode, we dive into early-season sea lice data and rising ocean temperatures that are already signaling a challenging year for Norwegian salmon farms. From warnings of heat-driven outbreaks to shifting regulations and market pressure, we break down why 2025 could be another pivotal year for fish health strategy. Then, stay tuned for a conversation with oceanographer and Senior Researcher, Dr. Helene Langehaug of the Nansen Environmental and Remote Sensing Center (NERSC), who explains the science behind marine heatwaves, their classifications, and what this year’s climate models are telling us about what’s coming next.
