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: In this study, a high-quality chromosome-level genome of Apostichopus japonicus was constructed using Pacbio HiFi long-reads and Hi-C sequencing data. The assembled genome had a total length of 671.60 Mb, with contig N50 size of 17.20 Mb and scaffold N50 size of 29.65 Mb. A total of 19,828 genes were annotated, and 97.2% of BUSCO genes were fully represented. This high-quality genome of A. japonicus will contribute to the development of sustainable aquaculture practices and provide insights into their genetic makeup, evolutionary history, and ecological adaptation.

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: 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: CMNV, a covert mortality nodavirus, was found to infect sea cucumber Apostichopus japonicus, causing various pathological lesions in tissues including muscle necrosis. This infection could potentially impact larval rearing and has implications for aquaculture in China. Sea cucumber is an important species in Chinese aquaculture, and further study of CMNV infection in this species is needed to understand the full implications.

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: Sea cucumbers are affected by microplastic fiber transfer, but they can recover from the effects. Single transfer does not significantly impact their growth, but repetitive transfer decreases the growth rate.

Summary: Sex-specific markers were identified in sea cucumbers using a 2b-RAD-seq method, leading to the development of an efficient genetic sex identification method. This study sheds light on the sex determination mechanism in sea cucumbers and will enhance genetic and sex control breeding efficiency in this species.

Summary: This study investigated the individual and combined toxicities of cadmium (Cd) and microplastics in Apostichopus japonicus and their effects on growth, Cd tissue accumulation, digestive enzymes, and gut microbes. Exposure to high concentrations of Cd and microplastics led to decreased body weight gain and specific growth rate. Cd content increased in the respiratory tree, digestive tract, and body wall. Digestive enzymes, such as amylase, lipase, and trypsin, decreased in the group exposed to high concentrations of Cd/microplastics. Firmicutes, especially Lactobacillales, were significantly reduced in multiple treatment groups. Cd had the greatest negative impact, but the presence of microplastics increased its toxicity.

Summary: In this study, an eco-friendly method for rearing sea cucumber larvae was developed by providing a suitable living environment in open-air outdoor ponds using a cage system. The optimal stocking density and substrate were identified to improve survival and settlement of A. japonicus larvae.

Summary: The pacifastin gene Ajpacifastin-like was cloned and characterized in Apostichopus japonicus, showing ubiquitous expression in all tissues with the highest expression in muscle. The protein encoded by Ajpacifastin-like acts as an immunomodulatory factor via phenoloxidase to mediate phagocytosis by coelomocytes in pathogen-challenged A. japonicus.

Summary: The study found that sea cucumbers exhibit different behavioral and physiological responses to the circadian rhythm. These findings suggest that aqua-farmers should consider carrying out seeding at night and providing diets before the peak of sea cucumber feeding at night. The study also revealed that cortisol concentration is higher at night, indicating that sea cucumbers may be more stressed during this time. However, 5-HT and melatonin are not significantly affected by the circadian rhythm. Overall, this study provides valuable insights into the behavior and physiology of sea cucumbers and their aquaculture.

Summary: The study found that dietary exposure to MFs did not significantly affect the growth and fecal production rate of sea cucumbers, but disrupted immunity and oxidative stress indices. These indices may serve as potential biomarkers of MF ingestion in sea cucumbers.
