Sea cucumbers are increasingly exploited for human consumption and for their curative properties, and many wild populations are now depleted or in danger of extinction. While aquaculture is seen as an alternative to fisheries and as a mean to restore wild populations, more knowledge is needed on their reproductive strategies to render this practice efficient, notably for fissiparous holothurian...

Five species of Caudinidae occur in New Zealandwaters. Two new species are described: Paracaudina alta sp. nov.; Paracaudina reductia sp. nov. Two species reported previously are discussed: Paracaudina chilensis (Müller) and Paracaudina coriacea (Hutton). A lectotype has been established for P. coriacea (Hutton). Hedingia albicans var. glabra (Théel) is raised out of synonymy with Hedingia albi...

Sea cucumbers are the most important medicinal group among echinoderms. The presence of a wide range of natural bioactive compounds from sea cucumbers has been confirmed in many studies. This study was aimed to evaluate the antibacterial activities of ethanol, methanol and acetone extracts from sea cucumber Holothuria parva. The sea cucumbers were collected during the low tide from Ola village,...

Oxytetracycline-resistant bacteria were isolated from a mariculture farm in China, and accounted for 32.23% and 5.63% of the total culturable microbes of the sea cucumber and the sea urchin rearing waters respectively. Marine vibrios, especially strains related to Vibrio splendidus or V. tasmaniensis, were the most abundant resistant isolates. For oxytetracycline resistance, tet(A), tet(B) and ...

Vibrio sp. strains JCM 18905 and JCM 19053 were isolated from a tetrodotoxin (TTX)-bearing scavenging gastropod, and Vibrio sp. strain JCM 18904 was isolated from a sea cucumber. All these are closely related to Vibrio alginolyticus. Their comparative genome information is useful for studies of TTX production in bacteria.

Rotational harvesting is one of the oldest management strategies applied to terrestrial and marine natural resources, with crop rotations dating back to the time of the Roman Empire. The efficacy of this strategy for sessile marine species is of considerable interest given that these resources are vital to underpin food security and maintain the social and economic wellbeing of small-scale and ...

Background: Sea cucumbers are highly prized seafood in Asia, where the demand for them has increased dramatically in recent years. However, nutritional information is only available for only a few of the commercially traded species. Methods: In this study, the biochemical composition of the sea cucumber Australostichopus mollis was evaluated in terms of the major functional components: collagen...

This study aimed to determine phylogenetic relationship between and among selected species of sea cucumbers (Echinodermata: Holothuroidea) using 16S mitochondrial ribosomal RNA (rRNA) gene. Phylogenetic analyses of 37 partial sequences of 16S mitochondrial rRNA gene using three main methods namely neighbour joining (NJ), maximum parsimony (MP) and maximum likelihood (ML) showed the presence of ...

background: malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. the present study was designed to investigate the ...
