Omega-3 fatty acids, particularly EPA and DHA, are fundamental to the health and development of both fish and humans. These long-chain polyunsaturated fatty acids (LC-PUFAs) contribute to optimal growth, robust health, and high-quality fish and shrimp, showing the connection between aquafeeds and the seafood we consume.
Fish require Omega-3s in their diets for a range of biological functions, including growth, immunity, and lipid metabolism. Studies conducted at BioMar’s Aquaculture Technology Centres have shown that providing the right levels of EPA and DHA through feed significantly enhances fish performance, robustness and product quality. Trials with species such as sea bream, sea bass, salmon and rainbow trout have demonstrated these fatty acids' critical role in fish nutrition.
The source of these nutrients is equally important. Traditionally, fish oil has been the primary source of EPA and DHA in aquafeeds. However, the increasing demand for sustainable alternatives has been motivated the use microalgae-based ingredients. These innovative solutions offer a responsible way to provide Omega-3s while reducing reliance on marine resources, minimising the pressure on wild fish stocks, and lowering aquaculture's environmental footprint.
On top of that, the fatty acid profile of fish fillets reflects the composition of their diet. This means that by tailoring feeds to include higher levels of EPA and DHA, farmers can directly influence the nutritional quality of the seafood they produce, delivering value to consumers.
Seafood enriched with Omega-3s offers exceptional health benefits for consumers. Essential for cardiovascular health, brain function, and reduced inflammation, these fatty acids are particularly important for neurodevelopment during pregnancy and early childhood. The European Food Safety Authority (EFSA) recommends a daily intake between 250 mg and 500 mg of EPA and DHA for adults, confirming their importance as part of a balanced diet.
Farmed seafood, such as salmon, sea bream, sea bass and trout, provides an accessible and responsible source of these nutrients. Moreover, the use of microalgae and other novel ingredients in aquafeeds ensures that consumers receive consistent and high-quality Omega-3s, regardless of the species they choose.

In today's world, the link between what we eat and how it impacts our health has never been clearer. When it comes to seafood, this connection is even more profound. It's not just "we are what we eat"—but "we are what we eat, eats." The diet of farmed fish and shrimp directly influences their nutritional value, making the quality of aquafeed a crucial factor in ensuring the seafood we consume is nutritious, healthy, and produced responsibly.
The link between what we eat and how it impacts our health has never been clearer. The food we eat plays a vital role in our health, and when it comes to seafood, this connection runs even deeper. It is not just about what we eat, but about what our food eats.
