This study investigated the capability for fin regeneration in zebrafish larvae with the mechanism of FCS isolated from green and purple sea cucumbers Apostichopus japonicus (G-FCS and P-FCS). HPGPC determined that mean molecular weight of purified G-FCS and P-FCS is 19.5 and 18.8 kDa, and the...

The purpose of this study was to assess the effects of a low temperature-resistant probiotic strain, Bacillus baekryungensis MS1, on the growth, nutritional quality, digestion and immunity of the sea cucumber Apostichopus japonicus under low temperature conditions. A feeding experiment was designed ...

Sea cucumber Apostichopus japonicus, an important marine benthic animal, is particularly sensitive to environmental temperature stress, which affected the growth, metabolism, and reproduction even survival. In this study, we used whole genome bisulfite sequencing (WGBS) to perform a comprehensive...

Kisspeptin neuropeptides encoded by the kiss-1 gene are endogenous ligands corresponding to G-protein-coupled receptor 54. It has been confirmed that kisspeptin neuropeptides (AjK1 and AjK2) exist in Apostichopus japonicus and participate in reproductive and metabolic regulation. In this study,...

Cyclin-dependent kinase 8 (CDK8) play a vital role in the regulation of essential biological processes such as cell proliferation and differentiation in various organisms. However, the immune functional of CDK8 in economic marine animals remains unclear. We aimed to explore the functional roles of...

Artificial rearing techniques of larvae and juveniles of the tropical sea cucumber, Actinopyga lecanora were developed for the first time. Broodstock individuals were collected in Yaeyama Islands, Okinawa, subtropical Japan and sorted by the gonad maturity which was determined by biopsy. An...

Low efficiency is one of the most serious problems of sea cucumber (Apostichopus japonicus) seed production in winter. Probiotics as dietary supplements have the potential to address this problem. The aim of this study was to investigate the effects of the application of dietary Bacillus...

Natural biofilms induce the settlement of sea cucumber Apostichopus japonicus larvae and have been applied to polyethylene corrugated plates (PCP) as settlement substrata in Chinese hatcheries. The method is technologically simple, but typically results in low efficiency of larval settlement, while ...

Based on 16S rRNA gene high-throughput sequencing technology, the microbial community structure in the gut of three tropical sea cucumber species, Holothuria atra, Stichopus chloronotus, and S. monotuberculatus, and their habitat sediments were analyzed. The OTUs in the gut contents of S....

The present study investigated the behavioral and physiological responses to the circadian rhythm in the sea cucumber Apostichopus japonicus. We found that righting behavior of sea cucumbers was significantly faster at night than that in daytime (P < 0.001). We thus suggest aqua-farmers carry out seeding at night in stock enhancement. The number of tentacle swings was significantly higher at night than that in daytime (P = 0.005). Thus, we suggest aqua-farmers provide...
