Higher dietary EPA & DHA levels improve commercial salmon farming productivity, predictability and sustainability
A large-scale, longitudinal study analyzing over 430 million Atlantic salmon across 556 generations has validated a critical link between dietary EPA and DHA levels and aquaculture performance. Results demonstrate that populations receiving higher levels (>9% TFA) exhibited significantly improved outcomes, including an 8% reduction in mortality, a 13% improvement in feed conversion ratio, and a 2% increase in harvest quality. Furthermore, increased EPA+DHA enhanced production predictability, reducing variability in key metrics.
From nutrients to nutrition: nitrogen pathways and seafood nutritional quality in the Black Sea - a systematic review
The Black Sea's rich fisheries—particularly small pelagic fish and bivalves—are a vital source of protein, omega-3s, and essential micronutrients. However, ongoing environmental degradation raises concerns about the long-term nutritional value of this resource. A recent systematic review, adhering to PRISMA 2020 guidelines, reveals a critical knowledge gap: while broader nitrogen pathways are documented, direct biochemical measurements within key species like horse mackerel and anchovy remain limited.
