Summary: This study identified 13,503 long noncoding natural antisense transcripts (lncNATs) in rainbow trout using 134 RNA-Seq datasets. Most of the lncNATs showed strong positive correlation with their corresponding sense transcripts. Differential expression analysis revealed that lncNATs complementary to genes related to immunity, muscle contraction, proteolysis, and iron/heme metabolism were differentially expressed following infection. lncNATs complementary to hepcidin, a master negative regulator of plasma iron concentration, were downregulated in resistant fish on day 5 of bacterial infection.

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: The study found that modifying hatchery-rearing practices, such as increasing the frequency of removing dead individuals, can effectively reduce losses caused by Flavobacterium psychrophilum. Specific measures include the frequency of dead fish removal, the probability of finding dead fish, and water flow rate. The evaluation of the model depends on assumptions about the initial number of infected individuals and virulence levels. Additionally, if the probability of hatchery personnel finding dead fish is lower, more frequent checks may result in greater gains.

Summary: The study showed that adding [Cu(NN1)(2)](ClO4) as a dietary supplement to rainbow trout for 15 days at doses of 29 and 58 μg/g fish did not affect growth, but resulted in changes in copper concentration in the intestine and muscle. High copper levels were detected in pond water after feeding with the complex. The administration of [Cu(NN1)(2)](ClO4) at 58 μg/g of fish for 15 days showed a 75% survival rate against F. psychrophilum.

Summary: Feeding rainbow trout with deoxynivalenol (DON) or partially feeding (pair-fed) can significantly reduce mortality rates when infected with Flavobacterium psychrophilum. Fasted or DON-fed fish showed increased autophagy in the liver, while fasted fish showed decreased autophagy in muscle. Treatment with chloroquine (CQ) increased Atg gene expression in the liver. The mechanisms behind the resistance of rainbow trout fed DON, CQ, or pair-fed to F. psychrophilum infection are still unclear.

Summary: The study found that the wild-type CSF-259-93 strain increased the production of FITB and FR 1 after exposure to iron-limiting media for 72 hours and 96 hours. In contrast, the vaccine strain B.17 showed a downregulation in SS expression at 72 hours. Furthermore, compared with the wild-type strain, B.17 exhibited elevated expressions of FITB, FR1, and SS at 0 hours, while TBomr1 had lower expression at 96 hours.

Summary: The intensive commercial production of burbot fingerlings relies on consistent supply of eggs and larvae throughout the year, which can be achieved by successfully spawning burbot outside their natural spawning season through manipulation of temperature and photoperiod. The study found that out-of-season spawning of burbot was successful, with no significant differences in egg production, fertilization, or larval growth and survival compared to in-season spawning. This method could be an important tool for ensuring a reliable supply of burbot fingerlings for commercial production.

Summary: Research shows that Burbot embryos are sensitive to temperature changes between 4.0°C and 5.5°C, with faster rates of warming causing greater harm. Family effects and incubation temperature influence deformity and survival of protolarvae. It is recommended that hydropower operations avoid thermopeaking during winter spawning of Burbot and maintain water temperatures below 3°C for at least the first two weeks.

Summary: Burbot have high economic value, low temperature requirements, and fast growth rate, making them a good candidate for cool or cold-water aquaculture. However, limited information exists on the immune systems of this species due to a lack of species-specific tools. In this study, an anti-IgM monoclonal antibody was developed and used to measure the specific antibody response of burbot following exposure to two pathogenic strains. The results demonstrate that the antibody specifically recognized burbot IgM and will be useful in characterizing the immune responses of this fish species.

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.
