  • Insights into the environmental conditions contributing to variability in the larval recruitment of the tropical sardine Sardinella lemuru
    Pata, Patrick R.; Yñiguez, Aletta T.; Deauna, Josephine Dianne L.; De Guzman, Asuncion B.; Jimenez, Cesaria R.; Rosario, Roselle T. Borja-Del; Villanoy, Cesar L. (Elsevier, 2021-07)
    The small pelagic fishery in the southern Philippines is one of the largest contributors to fisheries production in the country, and is dominated by the Bali sardine Sardinella lemuru. This species is a year-round spawner that has its peak spawning period during the northeast monsoon (NEM) months of November to February. However, there is still limited information on the conditions that affect this species’ survival during its early life history stages. Here, we attempt to discern the importance of temperature, prey density and advection on sardine larvae. The larvae were represented as passive particles that were released in known spawning grounds to simulate dispersal. The conditions the larvae experienced, namely, temperature and estimated prey density based on satellite chlorophyll-a values were recorded at each time step until the estimated recruitment age of 60 days. The temporal and spatial averaged conditions of recruited sardines showed that sardines spawned during the NEM months experienced higher chlorophyll-a, lower (more optimal) sea surface temperature, albeit higher advective loss, than sardines spawned during other months. Comparisons between years showed that during higher reported catch years, sardine larvae experienced lower temperatures and higher retention nearshore. Our results emphasize that sardine stock management efforts need to recognize the contribution of the temporally variable sardine environment to patterns in sardine recruitment and consequently in catches.

  • Visayan Sea fishing ban lifted
    Sornito, Ime (Panay News, Inc., 2020-02-19)
    It’s open season again for fishing in the Visayan Sea. The three-month fishing ban from November 2019 to February 2020 was lifted on Sunday, Feb. 16. The ban covered herrings, mackerels and sardines. Now fishermen could catch them again, according to the Bureau of Fisheries and Aquatic Resources (BFAR) Region 6.
  • Fisherfolk deplore waning catch due to 'overfishing'
    Arcalas, Jasper Emmanuel Y. (Philippine Business Daily Mirror Publishing, Inc., 2021-10-08)
    Sardine fishers in Dinagat Islands lamented their declining catch due to overfishing and harmful fishing practices of encroaching commercial fishers, who, they pointed out, are barred from municipal waters by law. Fisherfolk farmers revealed their sardine catch situation during a recent policy dialogue between their group and concerned government agencies such as the Department of Agriculture and Bureau of Fisheries and Aquatic Resources (BFAR). “[We had plenty of catches] before. But now, not anymore because we see fishing boats using superlight even closer to the shore. This drives us, small fisherfolk, farther into the deeper part of the ocean. Meanwhile, the commercial fishers using superlight are able to catch fish inside our municipal waters,” Eric Sarcauga, a sardine fisher from Dinagat Islands, was quoted as saying in a statement issued by nongovernment organization Oceana, the organizer of the virtual dialogue.
  • Fishing ban at Visayan sea lifted
    Nicavera, Erwin P. (Sun • Star Publishing, 2021-02-20)
    The Bureau of Fisheries and Aquatic Resources (BFAR) lifted the three-month closed fishing season in the Visayan Sea earlier this week. Under the Fisheries Administrative Order (FAO) No. 167-3 Series of 2013, the government places the Visayan Sea and its vicinities under closed fishing season from November 15 to February 15 annually. This is to ensure the protection and conservation of sardines, herrings and mackerels in the said fishing ground during their spawning period.
  • 3-month fishing ban on Visayan Sea ends in Feb.
    (Panay News, Inc., 2019-01-05)
    The closed season in the Visayan Sea for sardines, herrings and mackerels that started on Nov. 15, 2018 would end next month. “Prohibiting fishers from catching them will increase the population of these species. It is really for fishers so they can have increased catch and increased income,” said Regional Director Remia Aparri of the Bureau of Fisheries and Aquatic Resources (BFAR). The closed season will run until Feb. 15, stated BFAR’s Fisheries Administrative Order 167-3.
  • Int’l body accused of economic sabotage for listing Tawilis as endangered species
    Miraflor, Madelaine B. (Manila Bulletin, 2019-02-06)
    Switzerland-based International Union for Conservation of Nature (IUCN) has been accused of economic sabotage for listing Sardinella Tawilis, the only freshwater sardine in the world, as an endangered species, stakeholders said. The United Stakeholders of Taal Lake, which includes fishermen, vendors, restaurant owners and residents of communities surrounding Taal Lake, has “strongly condemned” the IUCN’s report in a position paper. IUCN said in its report that Tawilis, which is endemic to Taal Lake, has become endangered “due to overexploitation, pollution, and predation with introduced fishes, resulting in continuing declines in habitat quality and number of mature individuals”.
  • Increased sardines supply in W. Visayas
    Momblan, Gail T. (Daily Guardian Multi-Media Services, Inc., 2018-11-29)
    The Bureau of Fisheries and Aquatic Resources (BFAR)-6 reported a 1.2 percent increase in the supply of sardines in Western Visayas. The BFAR stock assessment data indicated that the region produced 28, 523 metric tons of sardines in 2017, a way higher that the 28, 185 metric tons produces in 2016. Remia Appari, BFAR-6 regional director, assured that Western Visayas has a steady supply of sardines.
  • 3rd Sardines Congress tackles sustainability
    (BusinessWorld Publishing Corporation, 2018-10-04)
    The 3rd National Sardines Industry Congress opened yesterday, Oct. 3, in Zamboanga City, dubbed as the Sardines Capital of the Philippines. The three-day event is focusing on the sustainable use of the fish resource, which is a major industry in the Zamboanga Peninsula Region. In a statement, the Bureau of Fisheries and Aquatic Resources (BFAR) said there will be “science sessions as well as industry-focused sessions” to be participated in by representatives from the local and national government, the commercial sector, academe, and non-government organizations.
  • Experts urging gov't to craft framework to protect sardines
    Macapagal, Jed Aldous (People's Independent Media, Inc., 2018-03-21)
    Experts are urging the government to craft a national management framework to address overfishing sardines in the country, citing declining stocks due to heavy fishing pressure and environmental changes. "Sardines are being overfished and existing policy measures are enough to protect them, especially spawning fish. To keep up with being caught too quickly, they biologically adapt by maturing early to compensate for their population loss. They remain small, and spawn less compared to ideal, mature sardines," a scientist from University of the Philippines Visayas.
