    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.

    Crabifier app to help identify mangrove crab
    Gahon, Shirley T. (Philippine Business Daily Mirror Publishing, Inc., 2019-08-12)
    Crabifier, a mobile app that identifies mangrove crab species at the juvenile stage, was recently launched. This mobile application was developed by the Technologies for Biodiversity Use and Conservation (TechBiodive) Unit of the De La Salle University (DLSU). It is an output of the mangrove crab project, “Integrating Genomics with Image Analysis and Geographic Information System Technology for Improved Rearing of Mudcrabs,” funded by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD). Headed by Dr. Ma. Carmen Ablan-Lagman and Dr. Chona Camille Vince Cruz-Abeledo of DLSU, the team that developed the app includes Southeast Asian Fisheries Development Center experts Dr. Ma. Rowena Eguia, Ann Francesca Laguna and Courtney Anne Ngo. The launch, which was held at the Multipurpose Hall, Bro. Andrew Gonzales, FCS, Hall, DLSU in July also launched another app, Biodiversity and Threats Monitoring App, BioMon.

    Gov't crafts masterplan for eel industry development
    Simeon, Louise Maureen (Philippine Star Printing Co., Inc., 2017-12-02)
    The Department of Agriculture (DA) is investing around P20 million to develop the local eel industry, with a focus on the sustainable utilization and conservation of resources. The DA-Bureau of Fisheries and Aquatic Resources (BFAR) is formulating a master plan for the nationwide development of the industry and implementation of sub-activities that will start next year. “The plan is focused on the development of studies on the culture of eel, nursery grow-out, feed formulation and farming systems, and sustainable resource utilization,” said Evelyn Ame, DA-BFAR national eel focal person.
