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.
Benthic life stages retain fjord-scale population structure despite pelagic dispersal
Understanding population structure in marine organisms with complex life cycles presents a significant ecological challenge. A recent study published by World Data Ocean investigated this dynamic in the scyphozoan jellyfish *Aurelia aurita* within a fjord system, combining genetic analyses, field observations, and hydrodynamic modeling. Findings reveal that despite high dispersal potential, benthic polyp populations maintain consistent genetic diversity, acting as a reservoir for the more variable pelagic medusa stage.
