Republic Act 9147 or the Wildlife Conservation and Protection Act became one of the protections for the wildlife in the municipality against illegal poachers. Thus, evaluating this law would be helpful especially to the Municipal Environment and Natural Resources Office (MENRO). Marine species provide important ecosystem services such as the provision of food, medicines, and livelihoods. It focused on three (3) aspects, namely; Advocacy, Activities, and Penalties. The research was conducted on the Office of the MENRO in the Municipality of Manay. The researcher did additional research and focus group discussion on the different activities being made by the agency for the implementation of the law specifically the Article 3 Sec. 27 of the RA 9147 along the coastal community namely; Central, San Ignacio, Holy Cross, and Zaragoza all in the Municipality of Manay, Davao Oriental. For triangulation purposes, separate survey questionnaires were answered by the community. The result showed that the community had knowledge of those endangered marine lives; however, they were not equipped with the right information about the prohibited acts under Article 3, Section 27 of the Republic Act 9147. Handfuls of chokepoints were also identified by the implementers and community such as the lack of IEC and insufficient budget for the implementation of the law. As a recommendation, there should be an intensified information education campaign, safeguarding of the marine protected areas, sufficient budget, strengthening the Bantay Dagat and the checkpoints for wildlife here in Manay.
