Optimizing Salmon Feed with EPA & DHA Enhances Farm Sustainability.
A 2023-2024 El Niño period saw fish oil shortages that can reduce dietary EPA and DHA, but a new large-scale study shows how maintaining these omega-3s can make salmon farming more resilient. Analyzing over 430 million Atlantic salmon, the research links higher dietary EPA+DHA levels to lower mortality and better feed efficiency. These gains also cut the carbon and marine footprints of harvested salmon. For producers, this is a clear path to more stable and sustainable operations.
Black Sea Seafood Nutrition: Tracking Nitrogen's Impact on Ocean Yields
The Black Sea's small pelagic fish and bivalves deliver essential protein and omega-3s, yet the nitrogen pathways that shape their nutritional value remain poorly quantified. This systematic review, following PRISMA 2020, finds a stark imbalance: ecosystem-level nitrogen dynamics are well documented, but direct biochemical data for key species like anchovy and Mediterranean mussel are scarce, with sprat nearly unstudied. Eutrophication-driven shifts may already be altering seafood quality. The gap between marine biogeochemistry and nutrition science demands integrated monitoring.
Mussel Nutrition Varies by Sex, Offering Insights for Aquaculture Practices
Sex matters even at the dinner plate. In a pilot study using farmed Mediterranean mussels purchased as food, we found that sex-based differences in nutritional value are anything but trivial. Female pools showed roughly 25% more total lipids and an order-of-magnitude higher EPA and DHA, alongside greater vitamin B12, iron, selenium, and iodine. Males carried more sodium and zinc. This points toward sex-targeted aquaculture as a credible route to nutrient-enriched products.
