Summary: The study aimed to determine the optimal dietary methionine requirement for juvenile sea cucumber Apostichopus japonicus selenka. The results showed that as dietary methionine levels increased, weight gain and specific growth rate initially increased and then decreased. Meanwhile, protein and lipid contents in body wall increased initially and then dropped, while amino acids content increased.

Summary: The study investigated the bioaccumulation and immune responses of sea cucumbers A. japonicus exposed to dietary Cr6+. Results showed the order of Cr accumulation in tissues and changes in enzyme activities with different concentrations of Cr6+ exposure. The study provided important insights into the effects of chronic dietary exposure of Cr6+ on sea cucumbers.

Summary: The study reveals that the kelp crab Pugettia ferox may cause significant predation mortality on commercially important Japanese sea cucumber Apostichopus japonicus, especially in areas releasing hatchery-produced juveniles. Furthermore, the unique ecological trait of Pugettia ferox utilizing freshly chopped sea cucumbers as decoration material and food storage is worth noting.

Summary: This study found that feeding Bacillus cereus LS2 could significantly improve the growth performance and immune parameters of sea cucumbers by activating specific pathways. Furthermore, LS2 diet could also influence the intestinal microbial composition of sea cucumbers by increasing the abundance of Actinobacteria and Bacteroidetes.

Summary: This study evaluated the effects of dietary zinc on the growth performance, digestive enzyme activities, antioxidant status, and immune responses of sea cucumber Apostichopus japonicus. The results showed that zinc supplementation significantly improved the growth performance and enzyme activities of sea cucumber, while also increasing antioxidant activities and reducing oxidative stress. However, excessive zinc supplementation caused oxidative stress. The study also revealed the dietary zinc requirement for juvenile sea cucumber.

Summary: This study found that dietary supplementation of taurine in sea cucumbers can promote growth and increase protein content, while significantly affecting the expression levels of related immune genes. The optimal taurine content in the diet of juvenile sea cucumbers was determined to be 3g/kg of the dry diet.

Summary: This study investigated the effects of selenium yeast on the growth, intestinal health, immune status, and body composition of juvenile Apostichopus japonicus. The results showed that moderate addition of selenium yeast promoted weight gain rate, digestive enzyme activity, and immune parameters, while high addition levels inhibited growth and digestive enzyme activity. These findings suggest that selenium yeast can benefit the growth, intestinal health, and immune status of juvenile A. japonicus when added at appropriate levels.

Summary: This study investigated the toxic response in the intestine of juvenile A. japonicus under sulfide stress. The results showed sulfide-induced intestinal inflammation and oxidative stress, as well as changes in gut bacterial composition and metabolic homeostasis. Interestingly, certain intestinal bacteria were found to be significantly correlated with metabolic changes. These findings provide new insights into the adaptation strategies of juvenile A. japonicus under sulfide stress.

Summary: Income breeding strategy allows all adults of sea cucumber to reproduce annually, even individuals with poor body condition and small maternal size. During reproduction, sea cucumbers allocate income resources to the demands of reproduction, growth and storage simultaneously, but income breeding also places a metabolic burden on the breeding adults.

Summary: This study compared the transcriptomes of sea cucumbers before and after exposure to cadmium (Cd) and/or microplastics (MPs), and investigated the changes in enzyme activity and content of certain compounds. The results showed that high concentration of MPs increased superoxide dismutase (SOD) activity. Combination treatment of high concentration Cd and MPs resulted in significant upregulation of various indicators and a large number of differential expression genes (DEGs). Cd exposure led to the upregulation of a protein associated with apoptosis and inflammation, while MPs exposure resulted in an imbalance of certain inflammatory proteins.

Summary: Laboratory experiments showed that microplastics and microfibers can transfer into the body wall of sea cucumbers, entering through the outer surface. In samples collected from the field, 86% of sea cucumbers were found to contain microplastics, mainly in the form of microfibers. The need to control microplastic pollution during the farming and processing of sea cucumbers was emphasized based on the findings of this study.

Summary: This study found that the low-temperature-resistant marine bacterium MS4 can significantly improve the growth performance and immune enzyme activity of sea cucumbers, while reducing the mortality of sea cucumbers infected with Vibrio splendidus. The intestinal flora structure of sea cucumbers fed with S. aquimarina MS4 differed from the control group, showing higher stability and abundance of certain bacteria. The expression of immune-related genes was upregulated significantly after the addition of S. aquimarina MS4 to the diet, indicating its potential in regulating the immunity and resistance of sea cucumbers to pathogenic bacteria.
