  • Fisheries Administrative Order No. 245-4: Series of 2018. Regulations and implementing guidelines on group tuna purse seine operations in high seas pocket number 1 as a special management area.
    (Department of Agriculture, 2018-07-25)
    This Administrative Order covers the 36 Philippine registered traditional group seine fishing vessels granted access to the HSP1-SMA, having gross tonnage of not more than 250 GT issued with International Fishing Permits, and listed in the WCPFC record of fishing vessels. It applies only to HSP-1 SMA, which is the area of the high seas bounded by the EEZs of the Federated States of Micronesia to the north and east, Republic of Palau to the west, Indonesia and Papua New Guinea to the south with exact coordinates as used by WCPFC Vessel Monitoring. Fishing access to operate in HSP1-SMA is granted on the basis of compliance to specific criteria. Compatible measure for the high seas and exclusive economic zones (EEZs) are implemented so that bigeye, yellowfin and skipjack tuna stocks are, at a minimum,maintained at levels capable of producing their maximum sustainable yield, as qualified by relevant environmental and economic factors including the special requirements of developing States in the Convention Area as expressed by Article 5 of the Convention. The vessels or the fishing company shall notify BFAR through electronic or any means the entry and the exit the HSP-1 SMA. Likewise, this information shall be transmitted to the adjacent coastal States / Territories and WCPFC. The report should be in the following format: "VID/entry or Exit: Date/Time; Lat/Long." The vessels operating in HSP-1 SMA should report sightings of any fishing vessel to the BFAR and WCPFC Secretariat Such information shall include vessel type, date, time, position, markings, heading and speed. The Bureau shall maintain an updated list of all fishing vessels operating in the I-ISP-i SMA based on the foregoing vessel's entry and exit reports submitted to WCPFC. The list will be submitted to WCPFC and will be made available to WCPFC members and other concerned stakeholders through dedicated website, www.bfar.gov.ph. Any violations of the provisions of this Fisheries Administrative Order shall be penalized with fines and penalties specified in the text.
  • Growth, nitrate uptake kinetics, and biofiltration potential of eucheumatoids with different thallus morphologies
    Narvarte, Bienson Ceasar V.; Genovia, Tom Gerald T.; Hinaloc, Lourie Ann R.; Roleda, Michael Y. (Wiley, 2021-12-30)
    The declining production of commercially important eucheumatoids related to serious problems like increasing susceptibility to ice‐ice disease and epiphytism may be ameliorated by nutrition. This ushered to an increasing interest in incorporating seaweeds into an integrated multi‐trophic aquaculture (IMTA) setup to take up excess inorganic nutrients produced by fish farms for their nourishment. In this regard, it is important to understand the nutrient uptake capacity of candidate seaweeds for incorporation in an IMTA system. Here, we examined the growth, nitrate (NO3‐) uptake kinetics and biofiltration potential of Eucheuma denticulatum and three strains of Kappaphycus alvarezii (G‐O2, TR‐C16 and SW‐13) with distinct thallus morphologies. The NO3‐ uptake rates of the samples were determined under a range of NO3‐ concentration (1‐ 48 µM) and uptake rates were fitted to the Michaelis‐Menten saturation equation. Among the examined eucheumatoids, only SW‐13 had a linear response to NO3‐ concentration while other strains had uptake rates that followed the Michaelis‐Menten saturation equation. Eucheuma denticulatum had the lowest Km (9.78 ± 1.48 µM) while G‐O2 had the highest Vmax (307 ± 79.3 µmol · g‐1 · min‐1). The efficiency in NO3‐ uptake (highest Vmax/Km and α) was translated into the highest growth rate (3.41± 0.58 % · d‐1) measured in E. denticulatum. Our study provided evidence that eucheumatoids could potentially take up large amount of NO3‐ and fix CO2 when cultivated proximate to a fish farm as one component of an IMTA system. During a 45‐d cultivation period of eucheumatoids, as much as 370 g NO3‐ can be sequestered by every 1 kg initial biomass E. denticulatum growing at 3% · d‐1. Furthermore, based on our unpublished photosynthetic measurements, the congeneric K. striatus can fix 27.5 g C · kg‐1 DW during a 12‐h daylight period.
  • Vulnerability drivers for small pelagics and milkfish aquaculture value chain determined through online participatory approach
    Macusi, Edison D.; Geronimo, Rollan C.; Santos, Mudjekeewis D. (Elsevier, 2021-11)
    Climate change impacts on the fisheries can be short-term or long-term, making them highly vulnerable. Fishers' vulnerability encompasses several factors and includes, among others, their sensitivity, exposure to the elements, and their adaptive capacity. The main aim of this study was to help develop a vulnerability assessment tool that can be applied in the various nodes of the fisheries and aquaculture value chains with a long-term view of enhancing the resilience of the fisheries and helping increase the adaptive capacity of the fishing communities. A participatory technique using online workshops was conducted together with various stakeholders (N = 214) who gave insights and suggested indicators that drive climate change impacts and vulnerability. Based on the online workshops conducted, the common hazards/drivers were increasing temperature, typhoons, flooding (sea-level rise), and the recent pandemic, which consequently destroy coral reef ecosystems, affect fisheries yield, increases fish mortality, damage boats, fishing gears, pens, cages, pond dikes, erode beach properties, and devastate houses. In association with these impacts, mobility, travel, processing, and logistic operations are severely reduced. In the human dimension, the fishers and fish farmers are directly affected in terms of income loss, destroyed fishing gears, nutritional deficiencies and health impacts, less fishing operations, early or reduced harvest yield, and low market value of products. In the adaptation options, the infrastructure, social, economic, awareness/knowledge, and relevant governance/policy dimensions are needed to address and help mitigate various climate change impacts.

    Multifaceted assessment of wastewater-based epidemiology for SARS-CoV-2 in selected urban communities in Davao City, Philippines: A pilot study
    Otero, Maria Catherine B.; Murao, Lyre Anni E.; Limen, Mary Antoinette G.; Caalim, Daniel Rev A.; Gaite, Paul Lorenzo A.; Bacus, Michael G.; Acaso, Joan T.; Miguel, Refeim M.; Corazo, Kahlil; Knot, Ineke E.; Sajonia, Homer; de los Reyes, Francis L.; Jaraula, Caroline Marie B.; Baja, Emmanuel S.; Del Mundo, Dann Marie N. (MDPI, 2022-07-19)
    Over 60 countries have integrated wastewater-based epidemiology (WBE) in their COVID-19 surveillance programs, focusing on wastewater treatment plants (WWTP). In this paper, we piloted the assessment of SARS-CoV-2 WBE as a complementary public health surveillance method in susceptible communities in a highly urbanized city without WWTP in the Philippines by exploring the extraction and detection methods, evaluating the contribution of physico-chemical–anthropogenic factors, and attempting whole-genome sequencing (WGS). Weekly wastewater samples were collected from sewer pipes or creeks in six communities with moderate-to-high risk of COVID-19 transmission, as categorized by the City Government of Davao from November to December 2020. Physico-chemical properties of the wastewater and anthropogenic conditions of the sites were noted. Samples were concentrated using a PEG-NaCl precipitation method and analyzed by RT-PCR to detect the SARS-CoV-2 N, RdRP, and E genes. A subset of nine samples were subjected to WGS using the Minion sequencing platform. SARS-CoV-2 RNA was detected in twenty-two samples (91.7%) regardless of the presence of new cases. Cycle threshold values correlated with RNA concentration and attack rate. The lack of a sewershed map in the sampled areas highlights the need to integrate this in the WBE planning. A combined analysis of wastewater physico-chemical parameters such as flow rate, surface water temperature, salinity, dissolved oxygen, and total dissolved solids provided insights on the ideal sampling location, time, and method for WBE, and their impact on RNA recovery. The contribution of fecal matter in the wastewater may also be assessed through the coliform count and in the context of anthropogenic conditions in the area. Finally, our attempt on WGS detected single-nucleotide polymorphisms (SNPs) in wastewater which included clinically reported and newly identified mutations in the Philippines. This exploratory report provides a contextualized framework for applying WBE surveillance in low-sanitation areas.
