Southeast Asian Fisheries Development Center, Aquaculture Department Institutional Repository (SAIR) is the official digital repository of scholarly and research information of the department. This is to enable the effective dissemination of AQD researchers' in-house and external publications for free and online. The repository uses DSpace, an open source software, developed at Massachusetts Institute of Technology (MIT) Libraries. It is an Open Archives Initiative (OAI)-compliant.

Initially, the repository shall contain preprints, full-texts or abstracts of journal articles, books and conference proceedings written by SEAFDEC/AQD scientists and researchers. The aim is to promote these publications especially those published in international peer-reviewed journals and generate higher citation through increased visibility.

It will also provide free access to all in-house publications of SEAFDEC/AQD. Full-text digitized copies of fishfarmer-friendly materials like books, handbooks, policy guidebooks, conference proceedings, extension manuals, institutional reports, annual reports (AQD Highlights), and newsletters (SEAFDEC Asian Aquaculture, Aqua Farm News, AquaDept News and AQD Matters) can be retrieved and downloaded.

In the future, SAIR will expand its collection to include images, presentations, audios, and videos among others.

The objectives of the repository are to: (1) to provide reliable means for SEAFDEC/AQD researchers to store, preserve and share their research outputs and (2) to provide easy access and increase the visibility of SEAFDEC/AQD scientific publications

SAIR also aims to encourage SEAFDEC/AQD researchers for self-archiving and submitting pre-prints from which metadata will be screened and approved by the library staff.

    A review of reported seaweed diseases and pests in aquaculture in Asia 

    GM Ward, JP Faisan, EJ Cottier‐Cook, C Gachon, AQ Hurtado, PE Lim, I Matoju, FE Msuya, D Bass & J Brodie - Journal of the World Aquaculture Society, 2019 - Wiley
    Seaweeds have been used as a food for centuries in Asia and are increasingly exploited as a source for dietary supplements, animal feed, chemicals, and biofuels. In recent years, there has been an increase in the prevalence of diseases and pests in these aquaculture crops, with a subsequent reduction in their quantity and commercial value. In this article, we review diseases that have been reported in the scientific literature for species of red and brown seaweeds. We have focused on the major seaweed crops grown in Asia, where much of this production is centered. We also provide information on disease management and biosecurity and some observations on future directions.

    A new species of the sanguinea-group Quatrefages, 1866 (Annelida: Eunicidae: Marphysa) from the Philippines 

    CJ Glasby, MAE Mandario, I Burghardt, E Kupriyanova, LM Gunton & PA Hutchings - Zootaxa, 2019 - Magnolia Press
    A new species of the Marphysa sanguinea group, M. iloiloensis n. sp. (Annelida: Eunicida: Eunicidae), is described from the Marine Annelids Hatchery of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC- AQD), Iloilo Province, Philippines. It represents the first record of this group in the Philippines. The new species is most similar morphologically to M. hongkongensa Wang, Zhang & Qiu, 2018, but can be distinguished from it by having fewer branchial filaments, a pair of faint eyes (absent in M. hongkongensa), and in slight differences in jaw morphology and chaetation. The embryos of the new species develop inside a jelly cocoon attached to the entrance of the adult burrow; this is the first time that egg-containing cocoons have been found in any species of the sanguinea-group. Phylogenetic analysis based on the mitochondrial gene cytochrome c oxidase subunit I (COI) revealed that Marphysa iloiloensis n. sp. is genetically distinct from all other analysed Marphysa species and forms a sister group to M. hongkongensa. A revised identification key to members of the sanguinea-group in Southeast Asia is provided.

    Fire + water + bombs: Disaster management among academic libraries in Marawi City, Lanao del Sur, Philippines 

    DL Superio, EM Abaday, MGH Oliveros, AS Delgado, VEV Palcullo & JF Geromiano - International Journal of Disaster Risk Reduction, 2019 - Elsevier
    The academic libraries in Marawi City, Lanao del Sur, Philippines are vulnerable to disasters. In the last ten years, the majority of the 13 respondent libraries have sustained at least one disaster that may have been caused by civil unrest, war or terrorism, flood, earthquake, or fire. The majority were unprepared to face such disasters, may it be small-scale or catastrophic, and only one library has a disaster management plan. The lack of significant holdings of rare books, shortage of financial resources, no perceived risk, and the unavailability of staff to write a disaster management plan, are the reasons why most libraries do not have a plan. Moreover, the majority lacked staff that has undergone training in disaster preparedness and management. On the other hand, all of the libraries have disaster management practices that although not enough, will still enable them to lessen the effects of the disaster and save their library and parts of their collection when necessary. The respondents identified management support as an essential factor in their success in disaster management. The results of the study provide valuable information on the current state of the libraries in the Philippines with regards to disaster preparedness and management. Therefore, it is an essential addition to the literature on disaster management in the Philippines, which is very scarce as of the moment.

    Evaluation of the bioremediation potential of mud polychaete Marphysa sp. in aquaculture pond sediments 

    MAE Mandario, VR Alava & NC Añasco - Environmental Science and Pollution Research, 2019 - Springer
    Organic enrichment from aquaculture could alter the chemical composition of the fishpond bottom by increasing the levels of organic matter (OM), sulfur (S), iron (Fe), and lower pH of the sediment. Polychaetes can contribute to the nutrient cycling and remediation of polluted sediment. A laboratory experiment was conducted to test the remediation potential of small and large mud polychaete Marphysa sp. introduced to two types of fishpond sediment. Initially, Sediment A had lower OM, S, Fe, and higher pH than Sediment B. After 30 days, in Sediment B, large polychaetes significantly decreased the OM level (27%) while both small and large polychaetes promoted significant decreases of S (71%) and Fe (70–73%) in both sediment types. The increase of sediment pH was promoted by the presence of polychaetes (0.53–0.69) although pH level in small polychaete was not significantly different with the no polychaete treatment. Regardless of polychaete treatment, the pH level of Sediment B (1.04 ± 0.10) was significantly improved than that of Sediment A (0.17 ± 0.02). In both sediments, large polychaetes (95%) had better survival rates than small polychaetes (73%). These findings reveal that large Marphysa sp. can significantly improve sediment quality by decreasing the levels of OM, S, and Fe and improve pH level to a more basic form without compromising its survival. Large polychaetes are recommended to be used as bioremediators of organically enriched aquaculture pond sediment.

    Induction of gonadal development in protogynous grouper with orally delivered FSH DNA 

    P Palma, J Nocillado, J Superio, EG de Jesus-Ayson, F Ayson, A Takemura, MW Lu & A Elizur - Marine Biotechnology, 2019 - Springer
    The availability of sexually mature fish often dictates the success of its captive breeding. In this study, we induced reproductive development in juvenile protogynous tiger grouper through oral administration of a plasmid (p) containing an engineered follicle-stimulating hormone (FSH). An expression construct (pcDNA3.1) was designed to express a single-chain FSH consisting of giant grouper FSH β-subunit and glycoprotein subunit-α (CGα), linked by the carboxy-terminal peptide (CTP) sequence from the human chorionic gonadotropin (hCG). Single oral delivery of pFSH encapsulated in liposome and chitosan to tiger grouper yielded a significant increase in plasma FSH protein level after 4 days. Weekly pFSH feeding of juvenile tiger groupers for 8 weeks stimulated ovarian development as indicated by a significant increase in oocyte diameter and progression of oocytes to cortical alveolar stage. As the pFSH treatment progressed from 20 to 38 weeks, female to male sex change was initiated, characterized by oocyte regression, proliferation of spermatogonial cells, and occurrence of spermatogenic cysts. It was also associated with significantly lower mRNA expression of steroidogenic genes (cyp11b, cyp19a1a, and foxl2) and basal plasma levels of sex steroid hormones 17β-estradiol (E2), testosterone (T), and 11-ketotestosterone (11KT). Results suggest that pFSH stimulates ovarian development up to cortical alveolar stage and then initiates sex change in tiger grouper. These findings significantly contribute to our knowledge on the role of FSH in the development of protogynous hermaphroditic fish. This study is the first to demonstrate induction of reproductive development in fish through oral delivery of plasmid gonadotropin.
