Summary: This study establishes the blood reference intervals for healthy and farmed juvenile Asian seabass 4-6 weeks after being stocked into marine aquaculture systems. The study also found weak but significant positive correlations between bodyweight and hematocrit, hemoglobin concentration, total plasma protein, and total red blood cell count. Additionally, abnormal blood values were associated with severe chronic granulomatous enteritis and depleted lipid stores in the liver.

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: Domestication processes and artificial selection in farmed rainbow trout leave signatures at a molecular level, with identified genomic regions containing genetic variants related to growth, development, reproduction, behavior, and immune system traits. This study detected several SNPs associated with candidate genes in interesting regions, providing insights into genetic traits of commercial importance.

Summary: Bacterial kidney disease (BKD) is a devastating bacterial infection in salmonids, and our study in Swedish waters with BKD-positive net pen farms found a high prevalence of Renibacterium salmoninarum (R. salmoninarum) in wild salmonids, indicating the risk of uncontrolled disease spread. The use of environmental DNA for monitoring BKD is challenging, but sediment samples show promise for detecting ongoing infections without sacrificing valuable fish.

Summary: This article discusses the reasons for the low efficacy of vaccines against the severe disease piscirickettsiosis in the Chilean salmon industry. Extrinsic factors including chronic stress, such as biotic and abiotic factors, and farm-management factors are considered as reasons for vaccine failure. Intrinsic factors including fish-related and pathogen-related factors are also discussed. Recommendations for improving vaccine efficacy are provided.

Summary: Thiamine deficiency complex is a major threat to salmonids, and natural dissolved pools of thiamine exist in the surface water and hyporheic zones of riverine habitats. Microbial communities in these habitats are related to the concentration of dissolved thiamine-related compounds, particularly in the hyporheic zone, which affects the conditions for salmon embryo incubation.

Summary: The expert system approach is still effective in scientific areas such as fish disease diagnosis where expert knowledge is required. In aquaculture, fish farmers lack the necessary expertise and equipment for accurate diagnosis, leading to the development of expert systems. This paper provides an overview of expert system approaches for fish disease diagnosis and proposes an improved system that can handle various types of fish diseases and provide explanations.

Summary: The aim of this study was to determine reference intervals in an outpatient population from Vall d'Hebron laboratory using an indirect approach previously described in a Dutch population. Reference intervals were calculated based on test results from individuals visiting general practitioners during 2018. The study found similar reference intervals between Vall d'Hebron and the Dutch population for tests following a normal distribution, but some differences were observed for certain biomarkers.

Summary: Cultured and wild Atlantic salmon are affected by sea lice. This study estimates the cost-effectiveness of sea lice management measures in Scotland and finds that skirts and the use of in-feed medicines are the most cost-effective. Integrated management strategies may reduce the risk of developing resistance.

Summary: This study evaluated the accuracy of different combinations of data transformation, outlier removal, and indirect techniques in establishing complete blood count reference intervals using large-scale data. The study found that outlier removal methods and indirect techniques significantly influence the final reference intervals, while data transformation has negligible effects, except for obviously skewed data. Furthermore, the choice of indirect techniques depends more on the characteristics of the analyte itself.

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.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
