Altering the fishery systems in Lagonoy Gulf (Pacific) where local artisanal and subsistence fishers are totally structured for their economic enterprise, require sustainable climate change adaptation measures. In achieving this end, the present study explored the indigenous fisheries practices of fishers, in phases of production, process, marketing, and management plan; determined adaptive strategies towards perceived influence of climate change in the habits of fishing activities; and assessed the knowledge and awareness of climate change adaptation amongst fishers and local officials.

For the statistics presentation on adaptive techniques, and knowledge and awareness on climate change, quantitative methodology have been considered. A whole of 25 experts participated in the focus group discussion (FGD) and key informant interview (KII). The manual coding of information frequency was carried out by indicating the wide variety of text that the respondents made for a specific statement. For the analysis, solely eight most recorded modifications have been considered. Finally, informants expressed pastime and aid to any local weather alternate initiative, and believed they are prepared to put up bayanihan efforts (a spirit of communal cooperation) to help hold the environment.
