Diel burying by the tropical sea cucumber Holothuria scabra: effects of environmental stimuli, handling and ontogeny

This study underscores that the circadian behaviours of marine animals can exhibit substantial spatial variation, may be absent at certain sites or seasons, and can be mediated by a complexity of factors that vary over short timescales.

Burying and feeding activity of adult Holothuria scabra (Echinodermata: Holothuroidea) in a controlled environment

Based on the results of this study, the most suitable time to conduct population surveys of H. scabra in the southern hemisphere would be during summer from midday to late afternoon.

Trial grow‐out culture of sea cucumber Holothuria scabra in sea cages and pens

The results of field trials conducted to determine the effects of size, grow-out period and site on the growth and survival of Holothuria scabra revealed significantly lower survival particularly of the small-sized group in Pilar and a decrease in the average weight of adults during the second half of the grow- out period.

Tank-Based Nursery Production of the Sea Cucumber Holothuria scabra in Various Seaweed Feed Regimens

This study explored the feasibility of Laurencia papillosa, Sargassum spp, and Gracilaria bailinae crude extracts as feeds for the juvenile sea cucumber Holothuria scabra in a tank-based system.

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.

Feeding and movement patterns of the sea cucumber Holothuriasanctori

Overall, the authors did not detect a clear “homing” behavior by H. sanctori, yet some individuals showed a fidelity for refuges when shelter availability was lacking, and organic matter consumption increased with OM availability, particularly during formation of the gonads.

Effects of photoperiod on daily activity rhythm of juvenile sea cucumber, Apostichopus japonicus (Selenka)

The behavior of the animals was significantly affected by different photoperiods, and the distribution rate of the Animals emerging at “daytime” increased with lengthening “light time” (except for the LD 3:21 cycle), which implies that 6–15 h light per day were the similar photoperperiods to natural sunlight.



Reproduction, growth and mortality of the holothurian Cucumaria pseudocurata

Certain phases of the ecology of a sea cucumber population at Shell Beach, Sonoma County, California, were investigated, finding that individuals live perhaps 5 years or more, and do not become reproductive until about the third year.

Biology of small juveniles of the tropical holothurian Actinopyga echinites: growth, mortality, and habitat preferences

The juveniles of A. echinites displayed a strong habitat preference for plate-like substrate types such as eroded limestone or dead coral plates, and two new types of skeletal spicules were discovered.

The effect of temperature-salinity combinations on survival and growth of juvenile Patiriella pseudoexigua (Echinodermata: Asteroidea)

Temperature and salinity had a significant effect on juvenile survival and growth and Variation in juvenile size was small immediately after metamorphosis and increased with time.

Growth of juvenile Actinopyga mauritiana ( Holothuroidea) in captivity

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.

Defensive mechanisms and ecology of some tropical holothurians

Research at Eniwetok Atoll suggests that many exposed coral reef invertebrates have evolved effective defensive mechanisms in association with high intensity predation, and Holothuria difficilis is best protected from predation.

Factors controlling spatial distribution of the sea cucumber Psolus chitonoides: Settling and post-settling behavior

The experiments indicated, in agreement with laboratory findings, that pentactula larvae settle gregariously, either on the adult, or (when the bivium is obscured by epizooites) by clustering around the margin of the adult sole.

Feeding rate and sediment reworking by the holothuroid Holothuria tubulosa (Echinodermata) in a Mediterranean seagrass bed off Ischia Island, Italy

Values of Holothuria tubulosa feeding rate range over an order of magnitude depending on individuals' size and environmental conditions, according to local differences in population structure, light and temperature regime.
