Transportation methods for restocking of juvenile sea cucumber, Holothuria scabra.
Type: Journal Article
The sandfish, Holothuria scabra, is a heavily exploited sea cucumber species. Minimising stress in the transportation of hatchery-produced sandfish juveniles to release sites is critical for successful restocking. Replicate ...
Sea cucumber identification cards: an analysis of their utility in the Pacific
Type: Journal Article
Fisheries management personnel and other stakeholders need a means of ensuring consistency when identifying the various species exploited within a fishery. We conducted a questionnaire-based survey to evaluate the usefulness ...
Taxonomy of the heavily exploited Indo-Pacific sandfish complex (Echinodermata: Holothuriidae)
Type: Journal Article
Two commercially valuable holothurians, the sandfish and golden sandfish, vary in colour and have a confused taxonomy, lending uncertainty to species identifications. A recent molecular study showed that the putative variety ...
Final stages of WorldFish-SPC sea cucumber project
Type: Journal Article
A joint WorldFish - Secretariat of the Pacific Community (SPC) project to restore to productive levels the breeding populations of sea cucumber, using the sandfish (Holothuria scabra) as the focal species, is in its final ...
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 ...
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 ...
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 ...
