Summary: Isolation of acid-soluble collagen (ASC) from snakehead fish by-products, such as skin and skin with scale, showed higher recovery from fish skin compared to the mixture. Both ASCs were identified as type I collagen and exhibited maximal solubility at pH 2. Collagen from the skin and scale mixture had higher imino acid content and thermal stability than fish skin ASC, suggesting the potential of snakehead fish as an alternative source of collagen.

Summary: The study found that SHVV is highly pathogenic to hybrid snakehead, leading to symptoms such as acute hemorrhages and enlarged visceral organs in infected fish. Histopathological analysis revealed significant inflammatory responses in major tissues of diseased fish infected with SHVV. The research also showed enhanced immune responses in hybrid snakehead after SHVV infection, providing insights into the pathogenic mechanism of SHVV and potential for future prevention and treatment strategies.

Summary: The study found that snakehead are capable of digesting starch efficiently, but diets with high carbohydrate content reduce the efficiency of digestible energy for energy retention. Snakehead prioritize digestible protein intake for protein gain. The estimated energy efficiencies of digestible protein, fat, and carbohydrates for energy retention were 53%, 79%, and 5% respectively.

Summary: This study aimed to investigate the effects of protein hydrolysate supplementation on the growth performance, feed utilization, and innate immune response of snakehead fish fed a low fish meal-based diet. The results showed that supplementation with tuna hydrolysate led to significant improvements in weight gain and growth rate. There were no significant differences in feed conversion ratio and protein efficiency ratio among all groups. Overall, the findings suggest that supplementing 2.5% tuna hydrolysate in the low fish meal-based diet can enhance feed intake, growth performance, and innate immunity in snakehead fish.

Summary: This study investigated the potential of using field two-spotted cricket as the main protein source in fish feed for striped snakehead juveniles. The 10-week feeding experiment showed that increasing levels of cricket meal inclusion in the diet improved growth performance, protein retention, and reduced waste outputs of nitrogen and phosphorus. The study concluded that cricket meal is a viable alternative protein source for aquaculture feeds, with the potential to reduce environmental nitrogen and phosphorus loading.

Summary: By constructing and analyzing three small RNA libraries of fish, we found that Echinacea purpurea can affect the immune activities of fish through miRNA-regulated ways. A total of 67 miRNAs (47 up and 20 down) were detected in the liver, 138 miRNAs (55 up and 83 down) in the spleen, and 251 miRNAs (15 up and 236 down) in the head kidney. Some miRNAs, such as miR-125, miR-138, and miR-181, have been identified to be involved in the innate and adaptive immune responses.

Summary: This study investigated the pathophysiological effects of Aeromonas hydrophila on snakehead murrel fish under sublethal conditions. Results showed higher bacterial load in muscle tissue and lower load in the kidney tissue of the infected group. Hematological parameters and serum protein levels were significantly decreased, while liver enzyme markers were elevated. Antioxidant genes were highly expressed in the liver tissue. Immune regulatory gene IL-8 was downregulated, while TGF-beta was upregulated. Various pathological changes, including swimming imbalance and fin injury, were observed during A. hydrophila infection.

Summary: The physicochemical characteristics of gelatin can be enhanced by altering the production process. This study investigated the effects of extraction time on physicochemical, functional group, and microstructural characteristics of snakehead fish skin-scale blended gelatin. It was found that the extraction time did not significantly affect the physicochemical properties of the gelatin, except for the color assessment. Micrographic analysis revealed changes in the surface structure of gelatin samples with different extraction times.

Summary: This paper describes the previously unstudied karyotypes of Channa lucius and C. striata from Phu Quoc Island and analyzes the trends of karyotypic evolution in the genus Channa. Comparative cytogenetic analysis showed that the main trend of karyotypic evolution of Channa species is associated with a decrease in the number of chromosomes and an increase in the number of chromosome arms, mainly due to fusions and pericentric inversions. The data obtained support the assumption that fragmentation and isolation of populations contribute to the karyotypic diversification of snakeheads and are of interest for further cytogenetic studies of Channidae.
