Episode notes
Wild Caught Isn't Always Safer
- Wild-caught fish often accumulate parasites and aren't automatically safer than farmed fish raised in clean conditions.
- James Arthur explains controlled aquaculture with clean feed prevents bioaccumulation and yields sushi-grade quality.
Childhood By The Sea Shaped His Path
- James Arthur grew up around the ocean: his father was a lifeguard and his mother worked at SeaWorld, shaping his marine passion.
- Early aquarium work and mentorship led him toward regenerative aquaculture projects years later.
Feed Determines Fish Nutrient Quality
- Fish nutrient density depends on feed: microalgae-fed fish deliver higher EPA/DHA and balanced omega-3/6 ratios.
- Seatopia quantifies EPA/DHA and omega ratios to compare fish and drive demand for healthier aquaculture.
