    Age, growth, and population structure of Conomurex luhunuas
    Sanchez-Escalona, Katherine; Aliño, Porfirio (National Fisheries Research and Development Institute, 2022-12)
    Age and growth dynamics of Conomurex luhuanus were investigated to determine the population structure. Age-specific change in shell shape determined with geometric morphometrics revealed discrimination of shape between 0-3 years old at 99–100% while 3–4 years old can be separated with 81% certainty. Using the age discrimination data, K and L∞ were estimated at 1.00 year and 7.28 cm, respectively. Recruitment is bimodal with natural mortality (M) of 0.71 and fishing mortality (F) approximated at 3.92 year. The exploitation rate (E) is 0.85 year, indicating probable overharvesting of the population under study. The presence of a deep-water population, age-specific burying behavior, and bimodal recruitment pattern are possible resilience factors.
    The study was supported by a grant from PCAARRD-DOST.

    DENR, PCSD begin case buildup vs 'traders' of Palawan giant clams
    Mayuga, Jonathan L. (Philippine Business Daily Mirror Publishing, Inc., 2021-05-16)
    The Department of Environment and Natural Resources (DENR) and the Philippine Council for Sustainable Development (PCSD) is now building a case against unscrupulous individuals behind the illegal trade of giant clams in Johnson Island and Green Island in Roxas, Palawan. The DENR said the illegal activity involving the harvest of some 300 pieces of giant clam shells in Johnson Island and 150 tons of giant clams in Green Island in March and April, respectively, constitute the crime of illegal wildlife trade. These are a violation of Republic Act (RA) 9147 or the Wildlife Resources Conservation and Protection Act of 2001.

    La Union board declares calamity state to deal with oil spill
    Sotelo, Yolanda (Philippine Daily Inquirer, Inc., 2013-03-01)
    The provincial board of La Union has declared the province under a state of calamity to enable towns affected by the oil spill supposedly from a sunken vessel or another ship to tap their calamity funds for cleanup operations. La Union Gov. Manuel Ortega said communities, various agencies and nongovernment organizations have been collaborating to remove chunks of hardened oil that have been spotted on La Union beaches. Many believe the oil sludge came from the Myanmar vessel MV Harita Bauxite, which sank off Bolinao town in Pangasinan last week. Others suspect it came from an unidentified cargo vessel, which docked near Bangar town in La Union, on Sunday.
