Summary: The study investigates escape incidents from Norwegian fish farms between 2010 and 2018, finding that most incidents are caused by technological factors, with net hole breakage being the most common cause of escape. These incidents may also have underlying human and organizational factors contributing to the escapes.

Summary: This study provides integrated reference intervals for 44 blood biomarkers for different age groups of intensively farmed Atlantic salmon, coho salmon, and rainbow trout in Chile. The variability of blood biomarkers depends on species, age range, and their interactions, highlighting the importance of improving health and welfare management for farmed fish.

Summary: This research aimed to estimate the withdrawal time for oxytetracycline in rainbow trout and Atlantic salmon after intraperitoneal administration. The study found that most samples met the market standards with a maximum residue limit of 200 μg/kg, but not with a limit of 10 μg/kg, and withdrawal times varied depending on the standard and species.

Summary: This study conducted bacterial sampling and analysis on outbreaks caused by warm-water and cold-water streptococcosis, using various phenotypic and genomic testing methods, and comparing antimicrobial susceptibilities of different strains. By sequencing the genome of the VS-1 strain, 69 virulence genes and 31 antimicrobial resistance genes were identified, providing comprehensive insights into the characteristics of V. salmoninarum.

Summary: The study identified an increased number of clock genes in salmonids, with some showing duplication and species-specific reciprocal gene losses. Several period genes in the clock gene family exhibit circadian rhythmicity, and most rhythmically expressed genes peak 2 hours before and after daylight.

Summary: This study reports the first detection of Flavobacterium psychrophilum in Korea and describes its genotypic and phenotypic characteristics. The study also reveals the pathogenicity and antibiotic resistance of the pathogen and proposes control measures. This is important for understanding the impact of this pathogen on Korean rainbow trout populations and establishing surveillance and control measures to prevent further transmission and outbreaks.

Summary: This study identified genomic regions associated with sea lice resistance in Atlantic salmon and rainbow trout through single-step Genome-Wide Association studies. Genes related to immune response, cytoskeleton function, and cell migration were found in important genomic regions for both species. Some genes were also involved in differences in inflammation response between resistant and susceptible fish of both species.

Summary: Two yellow-pigmented isolates, F-60(T) and F-392, were isolated from the internal organs of a healthy rainbow trout. Based on 16S rRNA gene sequence analysis, these isolates were identified as a novel species within the genus Flavobacterium, named Flavobacterium muglaense sp. nov. with F-60(T) as the type strain.

Summary: In this study, the impact of mechanical delousing (Hydrolicer) on the skin bacterial microbiome of broodstock female and male Atlantic salmon was evaluated. The results showed that Hydrolicer caused losses in alpha diversity in females and increases in alpha diversity in males. Furthermore, the skin microbial community composition underwent rapid shifts immediately after delicing in a sex-specific manner. The study suggests that female broodstock are more resilient to Hydrolicer treatment due to their more diverse skin microbiota community.

Summary: A novel Citrobacter species, identified as C. tructae, was isolated from the kidney of diseased rainbow trout, showing distinct phylogenetic and phenotypic characteristics compared to other Citrobacter species. The strain features Q-10 isoprenoid quinone, antibiotic resistance, and a plasmid.

Summary: A study aimed to develop a more sensitive reverse transcriptase real-time PCR assay to detect POMV, targeting segments 7 and 8 of the viral genome. The new assays showed higher sensitivity than the current method and could be a promising surveillance tool for detecting POMV in fish without symptoms.

Summary: This study aimed to validate the performance characteristics of two real-time PCR assays for detecting white spot syndrome virus (WSSV). The results showed that both assays had high sensitivity and specificity in detecting WSSV. Additionally, the assays demonstrated good repeatability in different sample types, indicating their reliability.

Summary: Two new real-time PCR assays were developed for detecting a broad range of Megalocytivirus genotypes, with different sensitivities and specificities compared to previously reported assays. The diagnostic capabilities of the assays were validated in RSIV-infected Japanese amberjack, showing equivalent sensitivity in dead fish and higher detection rate in asymptomatic fish for Cummins assay. Testing diagnostic capabilities of the assays using fish infected with other MCV genotypes is recommended.
