    Transcriptome analysis of growth variation in early juvenile stage sandfish Holothuria scabra
    Ordoñez, June Feliciano F.; Galindez, Gihanna Gaye S.T.; Gulay, Karina Therese; Ravago-Gotanco, Rachel (Elsevier, 2021-12)
    The sandfish Holothuria scabra is a high-value tropical sea cucumber species representing a major mariculture prospect across the Indo-Pacific. Advancements in culture technology, rearing, and processing present options for augmenting capture production, stock restoration, and sustainable livelihood activities from hatchery-produced sandfish. Further improvements in mariculture production may be gained from the application of genomic technologies to improve performance traits such as growth. In this study, we performed de novo transcriptome assembly and characterization of fast- and slow-growing juvenile H. scabra from three Philippine populations. Analyses revealed 66 unigenes that were consistently differentially regulated in fast-growing sandfish and found to be associated with immune response and metabolism. Further, we identified microsatellite and single nucleotide polymorphism markers potentially associated with fast growth. These findings provide insight on potential genomic determinants underlying growth regulation in early juvenile sandfish which will be useful for further functional studies.

    New hatchery for sea cucumber at SEAFDEC
    (TNT Publishing, Inc., 2010-05-14)
    At the price of $180 to 250 per kilogram (Php 12,000 per kg) of dried sea cucumber in the United States, sea cucumber are good bets for fish farmers wanting to find the new gold in aquaculture. This has driven South East Asian Fisheries Development Centre (SEAFDEC) Aquaculture Department, the research centre based in Iloilo, to develop the hatchery, nursery and grow-out technologies of the sea cucumber Holothuria scabra so that overexploitation of the wild fisheries on which the sea cucumber trade depends will cease or be minimized. Aquaculture can take the pressure off wild stock, enabling it to recover and allowing sustainable management plans to be put in place by local government units and people’s organizations in sea cucumber-rich areas.
