The Sardine Run is a spectacle of nature, but what's the science behind the chaos? Our latest Deep Dive podcast unpacks it all with marine biologist Mike Dyer.
The annual Sardine Run is a thrilling natural phenomenon, but what drives this incredible migration and the frenzy it creates? The latest episode of The Deep Dive podcast delves into the science behind the "silver stars" of the season.
This week, The Deep Dive hosts a conversation with marine biologist Mike Dyer. A respected expert in fish biology, Dyer is known for his engaging videos and profound knowledge of our oceans.
He unpacks crucial aspects of the sardine's life cycle, their mysterious migratory patterns, and the scientific principles behind the formation of those massive bait balls that ignite a feeding frenzy for marine life and people alike.

Meanwhile, In a recent episode of The Deep Dive podcast, Vinesh Soogreem spoke with fishing expert Dave Irving about how moon phases and tides affect fishing. Dave explained that spring tides during full and new moons bring stronger water movement, which can be great for targeting big fish like sharks — though they can also make some spots tougher to fish. Neap tides, with gentler movement during quarter moons, were better suited for calmer areas.
They also discussed rip currents, which Dave described as useful for surf fishing when anglers use them to spread bait and scent. Lastly, Dave noted that rising tides are ideal for deep-feeding fish at dawn or dusk, while falling tides can bring fish closer to shore.
It was a valuable conversation packed with tips to help anglers fish more effectively by reading the water and the moon.
