Omega-3 does not have to travel through wild fish.

EPA and DHA — the long-chain omega-3 fatty acids important for human nutrition and aquaculture — originate in marine microalgae. Fish accumulate them through the food chain. Yet a major industrial pathway still routes these nutrients through wild-caught small pelagic fish, fishmeal and fish oil, aquaculture feed, supplements, pet food and other markets.

This creates a strategic question:

If the nutrient begins in microalgae, why are we still relying so heavily on wild fish as the intermediary?

Below is a link to an early discussion draft exploring this question from a food-system, marine-ecosystem and bioeconomy perspective.

The document proposes a practical action plan for scaling algae-based EPA/DHA and reducing dependence on wild-caught marine ingredients. It is not a call for abrupt disruption of existing industries. The focus is on gradual diversification, functional replacement and building the next generation of marine-safe nutrient infrastructure.

The central idea is simple: we are not trying to replace millions of tonnes of wild fish one-for-one. We are asking which specific nutrient functions — especially EPA/DHA delivery — can be supplied through shorter, lower-pressure pathways.

The draft looks at:

• why the fishmeal and fish oil route is a long biological and industrial detour;
• why the replacement challenge is smaller when we focus on nutrient function rather than biomass;
• how algae-based EPA/DHA can reduce pressure on marine ecosystems;
• why existing marine ingredient companies and fish-processing regions should be part of the transition;
• how Europe can act while supporting a broader global shift;
• what practical questions companies, researchers and policymakers need to answer next.

This is a discussion draft, not a finished report. I am sharing it to invite comments, corrections and practical insight from people working in algae omega-3, aquaculture, feed innovation, marine ingredients, biotechnology, sustainable finance, public policy and food-system strategy.

The bigger question is not only about fish oil. It is about how Bioeconomy 2.0 can move from extracting biomass to producing essential functions more intelligently.
