Sea cucumber fisheries: global analysis of stocks, management measures and drivers of overfishing
These findings emphasize an imperative to support the enforcement capacity in low-income countries, in which risk of biodiversity loss is exceptionally high, and solutions for greater resilience of sea cucumber stocks must be embedded within those for poverty reduction and alternative livelihood options.
Daily burrowing cycle and feeding activity of juvenile sea cucumbers Holothuria scabra in response to environmental factors
Periodic movement, recruitment and size-related distribution of the sea cucumber Holothuria scabra in Solomon Islands
Spatial distribution, observed during tank experiments, suggested that adult H. scabra aggregated prior to spawning and in response to the lunar cycle, indicating that size distribution was a function of substratum type and depth.
Sea cucumbers. A global review of fisheries and trade
Sea cucumber fishing is not a traditional activity; however, a large number of coastal communities have developed a strong dependency on it as an alternative source of income. This paper reviews the…

This study uses results from an International Union for Conservation of Nature Red List assessment of extinction risk in all 377 known species of sea cucumber within the order Aspidochirotida to illustrate that anthropogenic variables can also predict extinction risks in marine animals.
Endogenous and exogenous control of gametogenesis and spawning in echinoderms.
Early development, settlement, growth, and spatial distribution of the sea cucumber Cucumaria frondosa (Echinodermata: Holothuroidea)
Overall, the growth rates were maximal during the spring and summer phytoplanktonic blooms with rising temperature, and field observations showed a size-dependent migration from photic to aphotic depths (≥40 m depth), when the animals reached sexual maturity.
Estimating dispersal distance in the deep sea: challenges and applications to marine reserves
It is proposed that a PLD that guarantees a minimum dispersal distance for a wide range of species should be used in the planning of marine protected areas in the deep sea, and more data are required to enhance accuracy and address the high variability in PLD between and within taxonomic groups.
Advances in sea cucumber aquaculture and management
The utilisation of sea cucumbers, including for human consumption, has been steadily growing over the years. Up-to-date information on the present status of world sea cucumber resources and…
