Certain species of holothurians (Echinodermata) are harvested in the shallow waters of the Indo-West Pacific region. They are processed into trepang or bêchede-mer, a delicacy amongst some oriental populations. This skilled activity was practiced in New Caledonia during the nineteenth and at the beginning of the twentieth centuries and is becoming popular once more (Conand, 1979). Similar renewed interest is also evident in other countries (Sachithananthan, 1972; Mottet, 1976; Gentle, 1979… 

Reproductive biology of the holothurians from the major communities of the New Caledonian Lagoon

The reproductive strategies of the species show a gradient that is probably related to the stability of the biotopes, with smaller species living in the more intrable outer reef flats and larger species in deeper lagoon floors.

Life-history biology of Peniagone azorica and P. diaphana (Echinodermata: Holothurioidea) from the north-east Atlantic Ocean

Comparison of the population structure of closely spaced samples suggests a patchy distribution on the bottom, and the benthopelagic lifestyle of adult P. diaphana suggests that the larvais also planktonic.

Reproductive cycle of the sea cucumber Holothuria (Platyperona) sanctori (Holothuroidea: Echinodermata) in the southwestern Mediterranean Sea: interpopulation variability

Temporal similarities of the gonad index (GI) and the sexual maturity stages suggest that the reproductive cycle of H. (P.) sanctori is annual with the main spawning event taking place from June to October, and temperature is the most likely factor influencing the reproductive cycles and spawning.

Ecology and Fishery Biology of Holothuria fuscogilva in the Maldives, Indian Ocean (Echinodermata: Holothuroidea)

The ecology of Holothuriafuscogilva was assessed in three habitats in the Republic of Maldives: marine grass beds, island gaps and lagoon floor. In the lagoon floor habitat, H fuscogilva was the

Population dynamics and reproduction of Holothuria tubulosa (Holothuroidea: Echinodermata) in the Aegean Sea

The reproductive cycle of the species showed a clear annual pattern which was highly correlated with the seasonal variations of temperature, and size–frequency distribution analysis was unimodal with the exception of spring where a second mode of larger sized individuals appeared.

Reproductive biology of the commercial sea cucumber Holothuria atra (Holothuroidea: Aspidochirotida) in the northwestern coastal waters of Sri Lanka

The reproductive biology of Holothuria atra, the most abundant and widely distributed commercial species, was investigated in the northwestern coastal waters of Sri Lanka from July 2008 to 2009 and found that synchronous seasonal gametogenesis with some asynchrony among individuals during the prolonged spawning season and individuals with mature gonads were dominant throughout the year.

Reproductive biology of Holothuria (Roweothuria) poli (Holothuroidea: Echinodermata) from Oran Bay, Algeria

The results show that the maturation of the gonads occurs from March until May, and from May to July, the entire sampled population is at full sexual maturity, and it is only in July that spawning begins, which extends up to September.

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.

Reproductive Biology of Actinopyga echinites and Other Sea Cucumbers from La Réunion (Western Indian Ocean): Implications for Fishery Management

'Seasonal closure' using results on the spawning season during the warm waters period and 'minimum size' using size at first sexual maturity are tools for enhancing sustainable management of the fisheries.

Reproductive cycle, development and recruitment of two geographically separated populations of the dendrochirote holothurian Aslia lefevrei

The boreo-mediterranean holothurian Aslia lefevrei (Barrois) occupies cryptic habitats from low-water mark to ca. 20 m. During the present work specimens were collected from the west coast of Ireland



Patterns of reproductive periodicities in four species of indo-pacific echinoderms

Sea temperature seems to be important in regulating the reproductive periodicities of at least two of the species, including Echinometra mathaei, which is reproductively active at all times of the year throughout most of its distribution, except when north of about 27° N. latitude when reproductive activity is limited to the summer months.

Fifty-one new species were discovered, and some are here described for the first time; many of these and others are illustrated by photographs, and a number are represented in their natural colours from drawings by Mr. E. M. Grosse.

This review organizes ideas on the evolution of life histories into more comprehensive theory that makes more readily falsifiable predictions, and examination of different definitions of fitness.
