“…This suggests that the diet is the main factor leading to the separation of PC1, further proving the ability of transforming microbiome in the fecal diet. Moreover, the sea cucumbers fed with the same diet at different water temperatures were both separated by PC2, suggesting that water temperature is the main factor causing the separation of PC2 due to the reason that different temperatures create different bacterial predominance (Feng et al, 2021). The results of the PCA are consistent with the results of the community richness and community diversity analyses.…”

Improving the aquaculture production efficiency by appropriate diets is an essential approach to meeting the increasing market demand for sea cucumbers. The feces of sea urchins, which contains various enzymes and microorganisms, is a potentially cost-effective food for sea cucumbers. To assess the usability of the fecal diet, a five-week laboratory simulation is conducted to investigate behaviors, digestion ability, growth and resistance ability of the sea cucumber Apostichopus japonicus fed with fecal diet at water temperatures of 15°C and 5°C. In the present study, A. japonicus fed with fecal diet shows an obvious preference to fecal diet rather than prepared feed at water temperatures of both 15°C and 5°C, which suggests that the feces is an applicable diet for A. japonicus. Furthermore, small A. japonicus fed with feces (group F) shows significant advantages in intestinal community richness, community diversity and intestine protease activity to A. japonicus fed with prepared feed (group S) at 15°C. These results indicate that the fecal diet provides benefits to digestion ability of small A. japonicus at 15°C. Weight gaining rate is significantly higher in the A. japonicus fed with feces than that in A. japonicus that were fed with feed or not fed with food (group C), which suggests that the direct improvement of the production efficiency at 15°C. The advantages in intestinal bacteria, protease activity, and growth are consistently found in group F compared with group S at 5°C. In addition, the composition of intestinal bacteria indicates that sea cucumbers may inherit the intestinal bacteria of sea urchins through fecal consumption. This suggests that the fecal diet enhances the digestion ability and enzyme activity at low water temperature and thus improves the growth of sea cucumbers. Furthermore, sea cucumbers fed with sea urchin feces have the highest survival rate among the three groups in exposure to an acute salinity decrease at both 5 and 15°C, indicating a better resistance to low salinity. This provides a new insight into the geographical expansion to low-salinity areas in sea cucumber aquaculture. In conclusion, the present study suggests that sea urchin feces have a great potential for the application in improving the production efficiency of sea cucumber aquaculture.

“…Sea cucumber (Stichopus japonicus) is a marine organism in the most benthic marine habitats along the Asian coast. In China and other Asian countries, sea cucumber has been used as a traditional tonic and food with high nutritional value for hundreds of years. , Studies have demonstrated that sea cucumber has anticancer benefits, anti-inflammatory effects, antioxidant activity, antimicrobial properties, and so forth. , It is rich in bioactive compounds, such as proteins (e.g., collagens), lipids (e.g., n-3 and n-6 fatty acids, triglycerides, and phospholipids), polysaccharides, and minerals. , Lipids are particularly indispensable to the survival and growth of sea cucumbers with unique biological and pharmacological properties. Han et al reported that the eicosapentaenoic acid (EPA)-enriched phospholipids in sea cucumbers exhibited a significant effect on ameliorate insulin resistance and elevated the hepatic lipolysis level .…”

“…It was found that many reactions can occur in dried seafood during storage . The oxidation of unsaturated fatty acids (UFAs) is a common reaction because the double bonds of UFAs are vulnerable to oxygen, and the proportion of UFAs bound in phospholipids in sea cucumbers is high . Such a lipid oxidation reaction is the main reason for the deterioration of dried seafood during storage and can induce quality loss (e.g., nutritive value, color, texture, and flavor) and generate toxic compounds .…”

Sea cucumber (Stichopus japonicus) is one of the most luxurious and nutritious seafoods in Asia. It is always processed into dried products to prevent autolysis, but its quality is easily destructed during storage. Herein, an extremely simplified workflow was established for real-time and in situ quality assessment of dried sea cucumbers (DSCs) during storage based on the lipid oxidation characteristics using an intelligent surgical knife (iKnife) coupled with rapid evaporative ionization mass spectrometry (REIMS). The lipidomic phenotypes of DSCs at different storage times were acquired successfully, which were then processed by multivariate statistical analysis. The results showed that the discrepancy in the characteristic ions in different DSCs was significant (p < 0.05) with high R 2(Y) and Q 2 values (0.975 and 0.986, respectively). The receiver operating characteristic curve revealed that the ions of m/z 739.5, m/z 831.5, m/z 847.6, and m/z 859.6 were the most specific and characteristic candidate biomarkers for quality assessment of DSCs during accelerated storage. Finally, this method was validated to be qualified in precision (RSDintraday ≤ 9.65% and RSDinterday ≤ 9.36%). In conclusion, the results showed that the well-established iKnife–REIMS method was high-throughput, rapid, and reliable in the real-time quality assessment of DSCs.

The phylum Echinodermata comprising the classes Asteroidea, Ophiuroidea, Echinoidea, Holothuroidea, and Crinodeia, is one of the important invertebrate groups. Members of this phylum live exclusively in marine habitats and are distributed in almost all depths and latitudes. Some of them, such as sea urchins and sea cucumbers, are commercially valuable and constitute a major fishery resource. Echinoderms are increasingly recognized as a unique source of various metabolites with a wide range of biological activities. The importance of dietary polyunsaturated fatty acids, such as eicosapentaenoic acid, in human health has drawn attention to echinoderms as a promising source of essential fatty acids (FAs). Extensive information on the FAs of the phylum has been accumulated to date. The biosynthetic capabilities and feeding habits of echinoderms explain the findings of the unusual FAs in them. Certain common and unusual FAs may serve as chemotaxonomic markers of the classes. The main goal of the review was to gather the relevant information on the distribution of FAs among the echinoderm classes, describe the structures, distribution, biosynthetic pathways, and bioactivity, with an emphasis on the FAs specific for echinoderms. A large part of the review is devoted to the FAs derived from echinoderms that exhibit various biological activities promising for potential therapeutic applications.
