🐟Could FARMED FISH actually be healthier for you (and the ocean)?!

Arthur notes that parasites enter fish through infected feed (lower-trophic organisms); Copia’s feed is certified parasite-free, providing a second safety layer. His wife ate raw Copia fish during pregnancy without incident. The protocol aligns with what sushi chefs have long done behind the scenes.

Arthur modeled this after the FDA’s reference doses for pregnant women. He made it the standard for Copia: if his wife couldn’t eat it liberally, it wasn’t acceptable. Host Casey Means shared that after a month of tuna in Hawaii, her functional-health labs showed spiked mercury, which normalized only after months of avoiding fish—illustrating how swiftly mercury can accumulate.

Arthur explains that feeding fish GMO corn, soy, and canola oil causes inflammation, fatty liver, and weakened immunity—mirroring human metabolic syndrome—forcing farmers to use prophylactic antibiotics. Aquaculture 3.0 returns to species-appropriate nutrition: microalgae for omega-3s (DHA/EPA), insect protein for salmonids (natural insectivores), and mycelium protein. This shift restores nutrient density and eliminates antibiotic dependence, but it demands a different business model because commodity markets won’t pay a premium. The change is analogous to the grass-fed beef movement: it requires consumer demand for measurable quality (omega-3s, low mercury).

Arthur details that through extensive testing, fish raised in plastic-lined tanks (recirculating systems) display no detectable microplastics in flesh when their feed is clean. The plastic from the tanks does not leach into the animal; the pathway is strictly dietary. Wild fish consume lower-trophic prey that have ingested microplastics, leading to bioaccumulation. Therefore, controlling what farmed fish eat—ensuring feed ingredients are free of microplastics—can produce seafood with no detectable microplastics, a standard Copia verifies on every lot.

Arthur explains that scallops raised in lantern baskets pull dissolved carbon from the water to build shells (calcification), permanently storing it. In integrated multi-trophic aquaculture, finfish waste is rich in ammonia, phosphorus, and nitrates, which fertilize kelp and filter feeders like oysters and mussels. These organisms then grow rapidly, creating massive carbon structures. Giant kelp can grow up to two feet per day. By placing such systems in previously nutrient-poor dead zones, you create oases of life that aggregate carbon. The ocean’s potential for carbon sequestration far exceeds land-based regenerative agriculture, but it’s often out of sight.

Arthur explains that many premium sushi restaurants freeze fish to these standards. Copia blast-freezes at harvest, stores at -30°C, and ships with dry ice and a thermometer to validate the cold chain. The feed is also certified parasite-free, providing a dual safety net. This allowed his wife to safely eat raw fish daily during her third trimester. He cautions that home freezers cannot reach the required temperatures to kill parasites.

Arthur explains that coal combustion releases mercury into the atmosphere, which deposits into rivers and oceans. Phytoplankton absorb it, and as larger fish eat them, mercury concentrates. Top predators can reach toxic levels, threatening species like killer whales. Regenerative aquaculture uses low-trophic feeds (algae) that bypass this chain, keeping mercury at <0.1 ppm, a level safe for daily consumption.
