The brown sea cucumber fishery is active in the Galapagos Islands since the year 1991 after its collapse in mainland Ecuador. This paper analyzes the Galapagos Sea cucumber fishery over the past decade and the reasons for its management pitfalls and chronic over fishing, and proposes an improved strategy for estimating stock size and harvest potential. Based on the historical distribution of th...

Holothuria atra is one of the most common sea cucumbers of intertidal zones in the tropical IndianPacific region. Asexual reproduction through transverse fission is a biological phenomenon which has already been studied, most notably in the south of the island of Taiwan (Chao & Chang, 1989; Chao et al., 1994), on the reefs of New Caledonia (Conand, 1989) and on the Great Barrier Reef in Austral...

This study was designed to explore the relationship between deterioration of sea cucumbers and intestinal flora’s diversity change during preservation using 16S rRNA gene sequencing. We show that body wall cucumber develops white spots on day 4, epidermis dissolves 7. The distinctive OTUs remain relatively low four days storage but increase potential gut microbiota biomarkers are Psychrobacter-...

Sea urchins and sea cucumbers, like other echinoderms, control the tensile properties of their connective tissues by regulating stress transfer between collagen fibrils. The collagen fibrils are spindle-shaped and up to 1 mm long with a constant aspect ratio of approx. 2000. They are organized into a tissue by an elastomeric network of fibrillin microfibrils. Interactions between the fibrils ar...

Five sea cucumber species including one new species of the genus Stichopus are reported from the shallow coral reefs of Straits of Malacca. The new species Stichopus fusiformiossa has unusual fusiform spicules in the tentacles, which are not found in the other species of the genus. Pseudo-tables and large perforated plates are newly recorded for Stichopus hermanni Semper, 1868 and Stichopus vas...

The increase in atmospheric CO2 due to anthropogenic activity results in an acidification of the surface waters of the oceans. The impact of these chemical changes depends on the considered organisms. In particular, it depends on the ability of the organism to control the pH of its inner fluids. Among echinoderms, this ability seems to differ significantly according to species or taxa. In the p...

Sea cucumbers are in high demand the world market due to their nutritional and medicinal values. In this study, growth performance of juvenile sea Holothuria scabra fed with different proportions two feeds was analyzed. Commercially available cucumber feed (feed-A) formulated (feed-B) were used for experiments. Animals 2% feed-A showed a negative rate. Maximum observed animals 8% feed-B. While ...

conclusions our results suggest that h. parva and h. oculata may be promising therapeutic candidates for the treatment of hcc, following further confirmatory in vivo experiments and clinical trials. results our results showed that h. parva methanolic extracts (250, 500, and 1000 µg/ml) and h. oculata methanolic extracts (200, 400, and 800 µg/ml) increased reactive oxygen species (ros) formation...
