    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.

    BFAR staff gain practical skills in milkfish aquaculture at SEAFDEC
    (Panay News, Inc., 2025-04-15)
    Another batch of personnel from the Bureau of Fisheries and Aquatic Resources (BFAR) trained at SEAFDEC/AQD on milkfish aquaculture from March 17 to 28, 2025 as part of the Philippines’ push to boost local production. The 12-day program gathered 14 personnel from various BFAR offices and facilities, including the Central Office and regional offices from Regions 3 (Central Luzon), 10 (Northern Mindanao), 11 (Davao), 12 (Soccsksargen), and 13 (Caraga). At the opening program, BFAR-3 Director Wilfredo Cruz emphasized the importance of a skilled workforce to support the National Bangus Development Program (NBDP) of the Philippines. “With this training, I hope we can reach our target and make the country self-sufficient in fry production,” he told the trainees.

    Spontaneous maturation and spawning of milkfish in floating net cages
    Marte, 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.

    Low 'bangus' price alarms Pangasinan fish growers
    Sotelo, Yolanda (Philippine Daily Inquirer, Inc., 2024-06-25)
    Reeling from the continuous tumbling prices of farmed “bangus,” fish cage operators in Pangasinan sought the intervention of the Bureau of Fisheries and Aquatic Resources (BFAR) and other concerned agencies to prevent the province’s multimillion-peso aquaculture industry from crashing. During a dialogue between bangus industry stakeholders and government agencies on June 21 at the National Fisheries Development Center here, growers of bangus (milkfish) said prices started to drop last February and is now at P90 to P110 per kilo. Last May, bangus, considered the country’s national fish, was still being sold in Pangasinan markets from P120 to P200 a kilo.

    MinDA gearing up to increase offshore milkfish farming output
    Francisco, Carmelito Q. (BusinessWorld Publishing Corporation, 2020-03-01)
    The Mindanao Development Authority (MinDA) said it will train aquaculture farmers starting this week to build up milkfish and white shrimp output, with a target of 10,000 offshore fish cages within two years. Secretary Emmanuel F. Piñol, the MinDA chairman, said the Fish Cage Development Program targets production of about 200,000 metric tons of milkfish a year, “which will infuse an estimated P26-B into Mindanao’s economy and provide thousands of jobs.”

    Heated tanks lead to productive milkfish spawning in cold months
    (Daily Guardian Multi-Media Services, Inc., 2021-02-27)
    A premier fisheries research center in the country is promoting a simple technology to address the perennial shortage of milkfish fry that continues to hound fish farmers in the Philippines during the colder months of the year. The Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD), a research center based in Iloilo, revealed that the facility succeeded in inducing milkfish breeders to spawn using thermal manipulation and is sharing this technology with fish farmers. “The shortage of milkfish seeds is more pron1ounced in the Philippines between November to February when the weather becomes too cold for breeders to lay eggs,” said SEAFDEC chief Dan Baliao, who further underscored that “thermal manipulation is necessary to help milkfish hatcheries stay productive during the four-month off-season by ensuring a continuous supply of seed.”

    Don't eat dead fish from oil spill-hit areas, BFAR warns
    Sornito, Ime (Panay News, Inc., 2020-07-08)
    The Bureau of Fisheries and Aquatic Resources (BFAR) in Western Visayas has issued a warning against eating dead fish in coastal areas contaminated by bunker fuel from a barge damaged by an explosion last week. Remia Aparri, BFAR regional director, said an undetermined volume of dead milkfish (bangus) fingerlings in fish cages were reported in the waters off Barangay Hoskyn in the capital town of Jordan, Guimaras. She explained that milkfish in fish pens are mainly prone to the threat of leaked bunker oil since they cannot swim out to the open sea.
