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 ...
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 ...
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 ...
