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.
Climate change-related stressors in aquaculture: modulation of gill microbiota and transcriptome in Atlantic salmon
Climate change poses a significant and escalating threat to aquaculture, particularly through rising temperatures, marine heatwaves, and jellyfish blooms. This study investigates the complex interplay of these stressors on Atlantic salmon (Salmo salar), focusing on gill health. Researchers utilized advanced sequencing techniques to analyze gill microbiota and transcriptome responses following exposure to elevated temperatures and jellyfish. Findings reveal a significant shift in microbial communities, notably increased Streptococcus and Staphylococcus, alongside altered gene expression related to immune response and tissue integrity.
A sustainable seaweed win-win: dietary fortification with Irish Wakame (Alaria esculenta) enhances Atlantic salmon (Salmo salar) muscle growth and modulates gene expression
Seaweed integration into aquaculture diets offers a compelling pathway towards sustainable food production. Recent research validates a significant benefit: dietary inclusion of *Alaria esculenta* (Irish Wakame) demonstrably enhances muscle growth and modulates gene expression in Atlantic salmon (*Salmo salar*). Utilizing contrast-enhanced computed tomography and transcriptomic analysis, scientists observed improved body condition and increased filet muscle area. These findings indicate that *A. esculenta* represents a valuable, sustainable functional food, positively impacting both salmon health and aquaculture practices—a clear win-win scenario.
