Summary: Copper alloy mesh (CAM) has been found to effectively prevent cryptocaryoniasis outbreaks. It has shown both killing effectiveness against the early stages of Cryptocaryon irritans and the ability to protect fish from infections. CAM has similar anticryptocaryoniasis effects as copper alloy sheets but with the advantages of being lightweight, low labor cost, and affordable. Additionally, CAM prevents the excessive accumulation of copper ions in aquaculture seawater.

Summary: The study found that sophoraflavanone G (SG), an active compound isolated from Sophora flavescens, showed anti-I. multifiliis effects. In vitro tests demonstrated that SG could effectively kill the parasite and reduce its infectivity. In addition, SG had low toxicity to fish and showed potential as a therapeutic agent against I. multifiliis.

Summary: The study showed that the red tilapia has a lower susceptibility to Cryptocaryon irritans infection compared to other marine fish species, and is effective in consuming tomonts to protect susceptible fish. Co-culturing Trachinotus ovatus with red tilapia resulted in a high relative survival rate after C. irritans infection, indicating potential for biocontrol of tomonts in marine aquaculture.

Summary: This study aimed to evaluate the function of manganese in Trachinotus ovatus immune protection against Crytocaryon irritans. The results showed that manganese enhanced monocyte phagocytosis, increased expression levels of immune factors, and improved pompano immunity. The colloidal manganese salt also provided immune protection and activated the cGAS molecule. These findings suggest that manganese could be a promising adjuvant candidate for C. irritans vaccine.

Summary: This study found that honokiol can induce apoptosis-like death in Cryptocaryon irritans tomonts. The results suggest that honokiol may induce tomont apoptosis-like death by disrupting calcium ion homeostasis, activating reactive oxygen species, and modulating apoptosis-related pathways.

Summary: Cryptocaryon irritans, the main pathogen of white spot disease in marine teleosts, is influenced by abiotic factors such as pH. This study examined the effect of pH on the life cycle of C. irritans and found that pH 6-9 is the optimal range for reproduction and infectivity. Extreme pH negatively affects the cleavage, hatching, and infectivity of the parasites.

Summary: A novel antiparasitic peptide So-pis was identified and characterized from Sciaenops ocellatus, showing potent antiparasitic activity against Cryptocaryon irritans. So-pis is genetically related to the piscidins family but exhibits lower overall conservation, with key features responsible for its biological activity against the white spot disease. This peptide might be a potential candidate for developing a novel therapeutic agent in combating marine white spot disease.

Summary: Cryptocaryon irritans causes significant economic losses in the pompano mariculture industry. This study evaluated the antiparasitic activity of 14 phytochemicals and found nerolidol to be the most promising compound. Adding nerolidol to the feed reduced the number of parasites on the gills and increased the survival rate of infected pompanos.

Summary: The study found that the marine microorganism B. licheniformis can inhibit the transformation of C. irritans and has an anti-C. irritans effect. Further research showed that B. licheniformis mainly exerts its anti-pathogen mechanism through energy metabolism, transcription and translation, lysosome-based degradation, and PI3K-Akt pathways.

Summary: In this study, a mucosal immunity model was constructed in Epinephelus coioides groupers after Cryptocaryon irritans infection. The levels of pathogen-specific immunoglobulin IgM increased in the serum, mucus, head kidney, gill and skin supernatants of the immune groupers. Additionally, an early response in the skin was observed, suggesting the importance of the mucosal immune system in the immune response.

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.
