Aquaculture is often discussed as a single category, but the reality is far more complex. The way fish or seafood are farmed – which species, under what conditions, and for whose benefit – determines whether the practice is restorative or destructive.
Industrial production of carnivorous fish, promoted as part of the so-called “blue revolution,” has created a paradox: while marketed as a solution to feed the world, it consumes vast amounts of wild-caught fish for feed, damages marine ecosystems, and privatizes coastal commons. Communities lose, ecosystems degrade, and the promise of sustainability rings hollow.
At the same time, other models of aquaculture – small-scale, non-intensive, or focused on bivalves and seaweed – can enhance biodiversity, capture carbon, and strengthen local livelihoods.
The Poseidon Project exists to clarify these distinctions. We provide evidence-based research, fresh perspectives, and accessible resources so that policymakers, consumers, investors, and journalists can make informed decisions. Our goal is to shine a light on harmful practices, highlight alternatives, and ensure that aquaculture, where it exists, supports both people and the planet.
