Summary: This research focuses on the infection of Lymphocystic Disease Virus (LCDV) in Amphiprion ocellaris and Amphiprion clarkii. LCDV was detected through histopathological study, observation of virus particles under an electron microscope, and gene sequence analysis. Symptoms of LCDV included white, stiff nodules on the body, skin, gills, and fins. The study found that the genotype of LCDV was closely related to a strain of LCDV from paradise fish in China.

Summary: The anthropause during the COVID-19 pandemic allowed wildlife to reclaim areas previously used by humans. The decline of sea anemones has resulted in a drastic decrease in the endemic Red Sea Clownfish (RSCF). A survey conducted before and after the pandemic showed that the number of RSCF doubled in 2021 compared to 2019, in correlation with the number of sea anemones. The study demonstrates the positive impact of COVID-19 closures on the increase of RSCF numbers.

Summary: Climate change is causing ocean temperature and pCO2 to rise, affecting sea anemones with Symbiodiniaceae. While high temperatures induce bleaching, increased pCO2 can enhance photosynthesis. Future temperature, but not pCO2 or their interaction, significantly reduced Symbiodiniaceae density in sea anemones, leading to bleaching events.

Summary: The stress hormone cortisol can regulate the expression of the kiss2 gene in yellowtail clownfish by binding to the glucocorticoid receptor (GR). Kiss neurons in the yellowtail clownfish express glucocorticoid receptors in different brain regions. The promoter of the kiss2 gene in yellowtail clownfish contains binding sites for glucocorticoid receptors, estrogen receptors, androgen receptors, progesterone receptors, AP1, and C/EBP. The transcription of the kiss2 gene can be enhanced by cortisol treatment through the GRE-dependent GR pathway.

Summary: Using clownfish as a research model, this study investigated the molecular regulatory network of social control on sexual development by performing transcriptomic analysis on the gonads of females, males, and nonbreeders. The results showed similarities between nonbreeders and males in both global transcriptomic profiles and histological characteristics, while identifying candidate genes involved in sexual development.

Summary: This study investigated the effects of different levels of DHA enrichment on the growth, survival, fatty acid profile, digestive enzymes, antioxidant parameters, and histology of yellowtail clownfish larvae. The results showed that a DHA concentration of 6% in rotifer enrichment was sufficient to fulfill the DHA requirements and maximize the growth rate of the larvae. High levels of DHA (36%) decreased larval survival, while the DHA12 group had the lowest growth due to lower digestive enzymes and antioxidant activities.

Summary: This study provides the first description of the depth distribution of Amphiprion frenatus in symbiosis with Entacmaea quadricolor in the Spratly Archipelago. It was found that the majority of A. frenatus inhabited sea anemones between 8-30 meters, with some recorded as deep as 45.9 meters. The deep-sea occurrence of A. frenatus cannot be explained by hydrophysical parameters.

Summary: When anemones bleach, it impairs the recruitment and survival of anemone-associated fish species, which highlights the risk of cascading mutualism breakdowns in coral reefs. Protecting these mutualisms is crucial for maintaining coral reef biodiversity.

Summary: This study investigated the distribution of kiss1 and kiss2 gene expressions in the brain of yellowtail clownfish using the RNAscope technique. It was found that kiss1 signal was mainly present in the dorsal habenular nucleus, while kiss2 mRNA was widely expressed in various parts of the brain, especially in the dorsal part of the nucleus of the lateral recess. Furthermore, there were sexually dimorphic distributions of kiss1 and kiss2 signals.

Summary: Among the ten species of anemonefish symbiotic anemones recorded for Vietnam, there are two main species, Entacmaea quadricolor and Stichodactyla mertensii, that maintain the presence of Amphiprion clarkii. A. clarkii has a continuous distribution in the coastal waters of Vietnam and nearby islands, with its southern boundary being the Con Son (Con Dao) Islands. The reason A. clarkii does not extend into the Gulf of Thailand is due to the absence of its main symbiotic sea anemones in that area.

Summary: Anemonefish, especially the yellowtail clownfish Amphiprion clarkii, has unique characteristics that make it an ideal model organism for studying genetic, ecological, evolutionary, and developmental traits. The publication of a high-quality genome assembly of A. clarkii, along with its unique traits, provides valuable insights into its evolutionary history, behavioral strategies, fish-anemone symbiosis, and color pattern evolution. The transcriptomic analysis also revealed tissue-specific gene expression patterns, contributing to a better understanding of this species. Overall, this study highlights the importance of A. clarkii as a model organism for scientific research in various fields.

Summary: The study demonstrates that in the interaction between clownfish and anemone, both remote and physical contact lead to a gradual convergence of their skin microbiota, which persists even after separation. The restructuring of microbiota may be associated with the recruitment of specific bacterial strains.

Summary: Coral-associated microbiomes exhibit significant diel dynamics, with most changes showing stochastic patterns possibly influenced by microspatial variation within coral colonies. Some microbial taxa, such as Porticoccus and Endozoicomonas, demonstrate cyclic changes in relative frequency over a 2-day sampling period, suggesting substantial variations in ecological functions of the microbiome over hourly timescales.

Summary: PCR-based assays have limitations in detecting multiple infecting agents and providing limited genetic information on pathogens. In contrast, untargeted, high-throughput sequencing can rapidly detect infecting agents and provide genomic sequence information. We explored methods to improve the sensitivity of NGS to detect respiratory and enteric viruses in poultry, and successfully reduced the abundance of host and non-target bacteria to increase the number of viral reads and improve pathogen coverage using negative enrichment strategies.

Summary: In this study, near-complete genome sequences of Sicinivirus from U.S. poultry flocks in 2003 to 2005 and Mexico in 2019 were reported. These sequences exhibit the highest nucleotide identity (84.5% to 85.5%) with other members of the Sicinivirus genus, providing updated knowledge on diversity and contributing to a better understanding of the molecular epidemiology of Sicinivirus.
