This study evaluated the metabolites of Anguilla bicolor during an outbreak of Anguilid Herpevirus 1 (AngHV‐1) disease. Two experimental groups, infected glass eels (P) and healthy glass eels (N), were established, with three biological replicates per group, each replicate comprising pooled samples from 10 glass eels (0.15 ± 0.03 g). Metabolomic analysis identified 212 compounds in the glass eel, including L‐palmitin, PC (18:1...

In 2023, all but one Swedish restocking farm rearing Baltic salmon and sea trout fry experienced massive mortality caused by lipoid liver disease (LLD). The struck farms used the same feed, and this was suspected to be the cause of the outbreak. We performed two parallel feed trials in three salmon populations as well as fatty acid and antioxidant analyses of feed and fish to investigate the causal relationship between the fee...

Infectious diseases among fish farms present significant challenges to fish health and production. Horizontal transmission serves as one of the main mechanisms driving outbreaks in these settings. The dynamics of horizontal transmission are influenced by pathogen properties, host characteristics and environmental factors. Additionally, the implementation of epidemiological interventions can further shape the patterns and conse...
