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 ...
Restocking the sea cucumber Holothuria scabra: sizing no-take zones through individual-based movement modelling
Type: Journal Article
The valuable sea cucumber Holothuria scabra, known as ‘sandfish’, has potential for restocking. However, there is little information available to determine the size of the no-take zones (NTZs) needed to protect the released ...
Grow-out of sandfish Holothuria scabra in ponds shows that co-culture with shrimp Litopenaeus stylirostris is not viable
Type: Journal Article
We examined the potential for producing the large numbers of sandfish (Holothuria scabra) needed for restocking programmes by co-culturing juveniles with the shrimp Litopenaeus stylirostris in earthen ponds. Our experiments ...
Releases of cultured sub-adult Trochus niloticus generate broodstock for fishery replenishment in Vanuatu
Type: Journal Article
The over-fished topshell Trochus niloticus ('trochus ') was cultured in Vanuatu and grown to sub-adult size (~40 mm) in sea cages. We released 200 of these trochus at each of five reef sites managed through Customary Marine ...
Restoring small-scale fisheries for tropical sea cucumbers
Type: Journal Article
Overfishing threatens to extinguish local fisheries for valuable tropical sea cucumbers by reducing population densities to the point where reproductive success trails behind natural mortality (known as depensation or the ...
Analysis of optimal habitat for captive release of the sea cucumber Holothuria scabra
Type: Journal Article
The success of marine stocking programs hinges on releasing hatchery-produced juvenile animals into the optimal marine habitat. This study sought to identify optimal microhabitat features of coastal seagrass meadows for ...
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 ...
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 ...
Sea cucumber culture, farming and sea ranching in the tropics: Progress, problems and opportunities
Type: Journal Article
Tropical sea cucumber mariculture has potential to become a profitable industry and contribute towards natural population replenishment. Here, we synthesise the fields of progress, current impediments and research opportunities ...
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). ...
