Summary: In large-scale aquaculture, medicinal plants like Mooseer can positively influence the fast growth rate of fish, while infectious diseases like Streptococcus iniae can cause economic loss. The study found that Mooseer extract inhibits S. iniae growth, enhances growth performance in rainbow trout, modulates serum biochemical and immunological parameters, and influences liver enzymes. The recommended dose of Mooseer supplementation in rainbow trout diet is 20 g/kg.

Summary: Artificial selection can enhance the adaptability of fish to temperature changes induced by climate change. However, attention to the genetic relationship between growth and robustness-related traits is necessary to avoid potential trade-offs.

Summary: The study introduces cross-trait assortative mating (xAM) as an alternative explanation for genetic correlations between different human traits, showing that xAM affects various phenotypes and can plausibly account for a substantial portion of genetic correlation estimates. The results suggest that previous reports may have overestimated the true genetic similarity between many phenotypes.

Summary: The study found that rainbow trout exposed to reuse water had lower survival rates, while vaccination could reduce the prevalence and load of IHNV and Flavobacterium psychrophilum. Different genetic lines showed variations in response to reuse water.

Summary: The study found a weak genetic correlation between susceptibility to bacillary necrosis and growth and survival in Mekong striped catfish, as well as a moderate favorable genetic correlation between growth and survival. To continue challenge testing in Vietnam, a strong genetic relationship needs to be established between bacillary necrosis and survival under a natural disease outbreak, requiring another field test.

Summary: The study in the Mexican white cypress breeding program in New Zealand found that there were unfavorable genetic correlations between diameter at breast height and canker severity score, indicating that selecting for improved diameter could increase susceptibility to cypress canker. Additionally, there were unfavorable genetic correlations between branch size and diameter at breast height. The moderate heritability estimated for canker severity score suggests that breeding values for this trait could be predicted accurately and included in the breeding program.

Summary: Outbreaks of pathogen-related diseases in fish are closely related to the temperature of the surrounding environment. Combining thermal stress and the presence of a novel viral pathogen may lead to a potential host jump and increased vulnerability of salmonid fish to a novel disease. Understanding the potential pathogenicity of the Tilapia lake virus (TiLV) in salmonids is important in the context of climate change and anthropogenic activities.

Summary: This study evaluated the short-term innate immune response of rainbow trout to infection with Y. ruckeri. The results showed significant decreases in hematological parameters and oxidative stress indicators in the infected group compared to the control group. There were also significant differences in gene expression between infected individuals and the control group.

Summary: This study investigated the performance differences among offspring obtained by intra- and inter-strain crosses using two shrimp strains, A and B, with outstanding WSSV resistance and growth, respectively. The results showed that crossbreeding can complement the advantages of different strains, with the cross of strain BA performing the best in terms of WSSV resistance and growth. The heritability estimates of body length and weight were medium, and there were significant genetic and phenotypic correlations among growth-related traits. The study provides important reference data for breeding disease-resistant and fast-growing shrimp strains.

Summary: Genetic correlation is a crucial parameter for understanding the relationships among complex traits. Existing methods for analyzing individual genotype data are not scalable to large datasets, while methods using summary data have reduced precision. This study introduces SCORE, a scalable and accurate method for estimating genetic correlation using randomized method of moments. SCORE achieves more precise estimates compared to summary-statistic methods, and it can be applied to large datasets in a computationally efficient manner.

Summary: The genetic parameters of three growth traits in redclaw crayfish were assessed, and it was found that the number of families affected the heritability estimates. Male crayfish had higher body weight and body length averages than females, while females had a higher carapace length average. There were strong positive genetic correlations between these growth traits. The results indicate that larger numbers of families could contribute to more accurate estimation of heritability.

Summary: Hypoxia poses a significant threat to the aquaculture sector and results in economic losses. This study focused on exploring the genetic potential for improving hypoxia tolerance in rainbow trout through a genome-wide association study. Several quantitative trait loci (QTLs) were identified, but they explained a relatively small percentage of the variance. However, the heritability of hypoxia tolerance was estimated to be moderate, suggesting the possibility of genetic selection to improve this trait. Additionally, potential candidate genes related to hypoxia tolerance were proposed.

Summary: This study demonstrated the virulence factor role of PdpA in F. noatunensis in fish, revealing differences in bacterial burden and gene induction during acute infection compared to the wild-type strain. Additionally, immunization with the PdpA mutant led to protection against a lethal dose challenge, highlighting the potential for further research on virulence factors within the genus Francisella using the zebrafish model.
