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.
Climate Stressors Reshape Salmon Gill Microbiome, Threatening Aquaculture.
Rising ocean temperatures and oxygen depletion are not distant threats; they are reshaping the gill microbiome of farmed Atlantic salmon, and the industry is catching up slowly. This study's identification of Streptococcus and Staphylococcus as biomarkers under heat stress, alongside transcriptomic shifts in immune and tissue-integrity pathways, offers a measurable, peer-reviewed foundation for adaptive management. The findings underscore that climate stressors act in concert, not isolation.
Seaweed Supplementation Boosts Salmon Growth, Reveals Genetic Insights
A single brown seaweed, *Alaria esculenta*, is proving that sustainable feed can do more than reduce environmental strain. In Atlantic salmon, its inclusion significantly boosted body condition and increased the muscle cross-sectional area of the valuable filet. The genetic picture is equally compelling: hundreds of genes shifted expression, touching on muscle and immune function. This is measurable, integrated evidence that functional feeds work.
