    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.
    The authors would like to thank Dr. Wilfredo Campos, Luke Felix, Dr. Rio Naguit, Denmark Recamara, and the Research for Sardines Volunteer Program (RSVP) volunteers for sharing sardine fisheries data; Arjay Cayetano for helping start the model used; and Iris Salud Bollozos for useful insights on larval ecology. This study was fully funded by the Department of Science and Technology–Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOSTPCAARRD) under the program, “Development of robust tools for managing sardine fisheries in the Philippines: Zamboanga Upwelling Bohol Sea System Program.” The authors declare no conflict of interest.

    Fish import service fee set at ₱500/ton
    Arcalas, Jasper Emmanuel Y. (Philippine Business Daily Mirror Publishing, Inc., 2021-09-13)
    The government is requiring traders to pay a service fee of P500 for every metric ton (MT) of fish they will import under the government’s small pelagic fish importation program, based on the supplemental guidelines issued by the Department of Agriculture (DA). This means that the government will earn as much as P30 million under the program, which allows eligible and accredited traders to bring in 60,000 MT of fish to beef up domestic supply. The DA has also required importers to ship their allocated volume from the country of origin within 20 days after receiving the sanitary and phytosanitary import clearance (SPS-IC) for their shipments.

    Davao plans for stronger fishery law enforcement
    Padillo, Maya M. (BusinessWorld Publishing Corporation, 2015-11-30)
    The City Agriculturist Office (CAO) is seeking a P3-million budget to strengthen the implementation of national and local fishery laws intended to protect marine and coastal resources. The project will involve closer coordination among the Barangay Fishery Law Enforcement Team, police-maritime group, the Philippine Coast Guard, Bureau of Fisheries and Aquatic Resources (BFAR) Region 11, the councils of the city’s coastal barangays, and the Barangay Fisheries and Aquatic Resources Management Councils. Rocelio T. Tabay, CAO assistant department head, said the project, which is part of the Fishery Resource Management Program, will help deter resource destruction and degradation. The Fisheries Code of the Philippines was amended in February through Republic Act 8550 while the city enforces its Comprehensive Fisheries Code passed in 2008.
