- Vulnerability drivers for small pelagics and milkfish aquaculture value chain determined through online participatory approachMacusi, 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.

Regulations requiring the installment of Juvenile and Trashfish Excluder Device (JTED) in trawls in Philippine waters.(Department of Agriculture, 2010-10-29)This Administrative Order, consisting of seven sections, establishes the Regulations Requiring the Installment of Juvenile and Trash Fish Excluder Device (JTED) in Trawls in Philippine Waters. This Order shall cover all commercial trawls in Philippine waters and prohibits for any person to operate fishing vessels using trawl nets, including all variations and modification of trawls without V12 or H15 JTEDs in Philippine waters. The construction and installation specifications are indicated in the attached device assembly technical data sheets, and shall be a requirement for the issuance of Commercial Fishing Vessel Gear License (CFVGL). Persons, associations, cooperatives, partnerships or corporations engaged in trawl fishing shall be given a period of three months from the effectivity of this Order to conform and/or comply with. The operator, boat captain or three highest officers of the boat who violates this Order shall upon conviction be punished by a fine equivalent to the value of catch or P10,000.00 Pesos whichever is higher, and imprisonment of six months, confiscation of catch and fishing gears, and automatic revocation of license.

- Ocean mapping and other marine activities of the National Mapping and Resource Information Authority (NAMRIA)Carandang, Efren P. (Philippine Council for Aquatic and Marine Research and Development, 2002)This paper describes the various marine activities being undertaken by the National Mapping and Resource Information Authority (NAMRIA) pursuant to its mandate as the central surveying, mapping and resource information agency of the government. NAMRIA gathers marine data through periodic hydrographic and oceanographic surveys and remote sensing techniques, and publishes the results in the form of nautical charts, bathymetric maps and other thematic maps. It also creates marine geographic information systems and databases. As steward of the National Oceanographic Data Center (NODC), the agency participates in international oceanographic data exchange programs, and also serves the marine data and information needs of the local marine science community. NAMRIA's data collection capability got a big boost with the acquisition this year of two multi-disciplinary survey vessels with state-of-the-art systems. With these vessels as platforms, NAMRIA will embark on the comprehensive charting of the Exclusive Economic Zone, and collaborate with the different marine science agencies in the conduct of multi-disciplinary oceanographic cruises.
- Defending Philippine maritime territory and marine resources: Initiatives and problemsCarranza, Ruben R., Jr. (Philippine Council for Aquatic and Marine Research and Development, 2002)The significance of the Philippines' maritime territory and the complexities of its defense are examined. The speaker highlights the integral role of the country's waters in trade, food security, and resource provision. Challenges, including naval limitations and maritime intrusions, are presented, followed by a discussion of defense strategies like selective sea control. The speech concludes with a call for decisive policy actions, diplomatic solutions to territorial conflicts, and improved capabilities to safeguard the nation's maritime interests.

- Spontaneous maturation and spawning of milkfish in floating net cagesMarte, Clarissa L.; Lacanilao, Flor (Elsevier, 1986-04)Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5–5.5 years (2.3–4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle has been completed in captivity. Milkfish at various stages of gonadal development were obtained in July–October 1980 and March–June 1981 derived from wild-caught fry, and in February–June 1983 from the hatchery-bred fish. The fish were held in floating net cages 9 m and 10 m diameter by 3 m deep, located in 7 m deep water off Igang, Guimaras Island, Philippines. Annual ranges of temperature and salinity were 25–33°C and 25–38 ppt, respectively. The fish were fed commercial feed pellet (42% protein) at 1.5–2% of body weight twice daily. Sexual maturation occurred during the natural breeding season of wild milkfish in the nearby waters. Gonadosomatic index (GSI) of mature males was 0.32–3.95 (wild-caught, 0.32–3.95; hatchery-bred, 1.71–3.85). For mature females it was 1.24–8.12 (wildcaught, 1.56–7.62; hatchery-bred, 1.24–8.12). Two spawnings were recorded in August 1980 and eight in May–July 1981 from the broodstock derived from wild-caught fry, with 342–6293 eggs collected from each spawning, while 14 spawnings were observed in May–June 1983 from the hatchery-bred fish, with 770–114 000 eggs collected. The time of spawning was between 23.00 and 02.00 h. Fertilization rate was 55–99% for the broodstock from wild-caught fry and 47–100% for the hatchery-bred fish. Hatch rate varied from 9 to 80%. Factors affecting spontaneous maturation, spawning and rematuration are discussed. Although slight improvements in egg collection were obtained, further innovations in egg collecting techniques will have to be developed. The results indicate the potential for hatchery production of milkfish fry from captive broodstock and for restocking of waters deprived of naturally occurring fry.
