Efficacy of chemical markers and physical tags for large-scale release of an exploited holothurian.
Type: Journal Article
Hatchery-produced juveniles need to be distinguished from wild conspecifics in order to evaluate the success of restocking experiments and stock enhancement. The commercially valuable sea cucumber Holothuria scabra, or ...
Changes in weight and length of sea cucumbers during conversion to processed beche-de-mer: filling gaps for some exploited tropical species
Type: Journal Article
Converting the weights or lengths of sea cucumbers in processed forms (e.g., salted or dried) to their original (live) measurement is essential for standardising data from fishery-dependent surveys and exports. We estimated ...
Preservation of genetic diversity in restocking of the sea cucumber Holothuria scabra investigated by allozyme electrophoresis
Type: Journal Article
Population genetics analyses should be considered when releasing hatchery-produced juveniles of the sea cucumber Holothuria scabra when spawners from nonlocal populations are used. In New Caledonia, within-region genetic ...
An external check for disease and health of hatchery-produced sea cucumbers.
Type: Journal Article
Sea cucumber diseases that arise in the hatchery can cripple production and undermine restocking programmes. A rapid protocol for the external examination of juvenile sea cucumbers was developed in order to screen for ...
Natural hybridisation does not dissolve species boundaries in commercially important sea cucumbers
Type: Journal Article
The study of species boundaries in areas of sympatry provides important insight into speciation processes. We investigated whether (i) two sympatric holothurians, Holothuria scabra and H. s. var. versicolor constituted ...
Ontogenetic changes in colouration and morphology of white teatfish, Holothuria fuscogilva, juveniles at Kiribati
Type: Journal Article
Little is known of the appearance or ecology of white teatfish (Holothuria fuscogilva) juveniles, which are very rarely found in the wild. In this study we use juveniles cultured in Kiribati to describe their ontogenetic ...
Developing technologies for restocking sandfish: Update on the WorldFish-SPC project in New Caledonia.
Type: Journal Article
The WorldFish Center project to develop strategies for restocking sea cucumbers is now in its fourth year. Its main purpose is to develop optimal release strategies for the restocking of sandfish (Holothuria scabra). ...
Effective fluorochrome marking of juvenile sea cucumbers for sea ranching and restocking
Type: Journal Article
Marking of skeletal body parts of marine animals with fluorochromes, such as tetracycline and calcein, can provide a valuable tool for mark-recapture studies. In recent decades, both fluorochromes have been used extensively ...
Spatio-temporal and size-dependent variation in the success of releasing cultured sea cucumbers in the wild
Type: Journal Article
Large-scale releases of cultured “sandfish,” Holothuria scabra, were used to examine size- and density-dependent effects on survival among sites. Juveniles were marked by fluorochromes in 3 size classes and released into ...
