Summary: This study demonstrates a size-dependent resistance to amoebic gill disease (AGD) in AGD-naive Atlantic salmon. Large salmon had lower gill parasite burdens and reduced AGD-related pathology compared to small salmon. Gene expression analysis revealed upregulation of genes associated with elevated immune activity in large salmon.

Summary: Through studying the pathogenesis of amoebic gill disease in Atlantic salmon, the localized and systemic immune responses of the host and parasite were identified, along with transcription factors and gene networks significantly altered in disease states. This dual transcriptomic study provides novel molecular insights into the pathology of AGD, offering alternative theories for future research and improved management strategies.

Summary: The Atlantic salmon industry in northern Europe is facing increasing losses due to amoebic gill disease (AGD). Genomic selection (GS) can potentially help reduce outbreaks and improve resistance to AGD. Linkage disequilibrium (LD) was evaluated in six Atlantic salmon breeding populations, and the use of genomic information for selection was investigated. The study found that LD decreased with increased physical distance between markers, and long-range LD was observed across all chromosomes. GS models had better performance than the pedigree-based best linear unbiased prediction (PBLUP) model. The use of genomic best linear unbiased prediction (GBLUP) model was recommended for the genetic evaluation of AGD resistance.

Summary: Amoebic gill disease (AGD) is a disease that negatively affects Atlantic salmon aquaculture by reducing fish performance and welfare. Despite progress in genetic selection, there has been limited focus on the response of interspecific hybrids to AGD challenge. This study found that the hybrids of Atlantic salmon and brown trout had a lower infection rate and improved gill signs of AGD, indicating their potential in fish disease management research.

Summary: This study reports the circulating plasma metabolome of Atlantic salmon infected with Neoparamoeba perurans, the causative agent of amoebic gill disease (AGD). The results show that low infection levels resulted in a more dramatic metabolomic dysregulation than advanced infection stages. The identified metabolites are potential biological markers for the systemic physiological impact of AGD.

Summary: A LD-based algorithm is proposed to allocate unassigned SNPs to chromosome regions from sparse genetic maps, with an average proportion of over 94% SNP accuracy in placing them to chromosomes in sugarcane, wheat, and barley. This approach can improve genome-wide association studies and genomic prediction in crop species with fragmented and incomplete genome assemblies, benefiting genomic-assisted breeding for orphan crops.

Summary: This study investigated the impact of altering branchial bacteria diversity and/or abundance on experimentally induced AGD in finfish species. Administration of oxytetracycline and chloramine-T significantly changed the bacterial load and diversity on the gill surface, affecting the community profile. The severity of AGD was slightly higher in fish treated with chloramine-T, suggesting a potential role for specific bacterial taxa in AGD development.

Summary: The study examined the effects of gill damage on Atlantic salmon by analyzing gill and liver tissues. The results showed that genes associated with wound healing and stress and immune responses were upregulated in moderately damaged gills and livers. Principal component analysis revealed that transcript levels in gills and livers could effectively differentiate different levels of gill damage. The gill damage-responsive biomarker genes and qPCR assays identified in this study will be valuable for future research on developing therapeutic diets for farmed salmon welfare improvement.

Summary: Complex gill disorder (CGD) is an important condition in Atlantic salmon aquaculture, but the roles of the putative aetiological agents in the pathogenesis are uncertain. This study shows that the loads of certain pathogens are significantly associated with the severity of CGD, and water temperature and management factors also have an impact on gill lesions.

Summary: This study aimed to generate a precise SV callset from whole-genome short-read sequencing (WGS) data for three commercial chicken populations and to evaluate the linkage disequilibrium (LD) patterns between the called SVs and surrounding SNPs. The results indicated that LD between deletions (DELs) and SNPs was similar to LD between SNPs, while LD between other SVs and SNPs was significantly reduced. The main reason for the reduced LD was the presence of local minor allele frequency differences. Genotyping accuracy was lower for duplications (DUP), inversions (INV), and translocation breakpoints (BND) compared to SNPs and deletions (DELs). The presence of tag SNPs was slightly lower for DELs compared to WGS SNPs, but this difference disappeared when considering SNPs located on different chicken genotyping arrays.

Summary: This study aimed to develop a novel gross pathological scoring system for assessing complex or multifactorial gill disease in farmed Atlantic salmon. The scoring system combines presumptive or healed amoebic gill disease (AGD) with other types of gill lesions, providing a standardized approach to characterize severe proliferative pathologies in affected gills.

Summary: Quantifying the level of linkage disequilibrium (LD) is important for genomic selection, and this study evaluated LD in Dual-Purpose Belgian Blue (DPBB) and compared it with Holstein. The results showed that LD in DPBB was generally lower than in Holstein, and the effective population size decreased over generations in both breeds. At least 68,000 SNPs are needed for implementing genomic selection in DPBB cattle.

Summary: This study investigated the growth and morphology of P. perurans isolates and found distinct differences between the clonal isolates. The isolates showed different growth patterns under similar conditions and responded differently to variations in temperature and salinity. These differences may be relevant to the virulence and proliferation potential of P. perurans on gills.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
