An application of fuzzy inference system to marine fish landings for west coast of Malaysia

Malaysia marine fishery sector and its activities are prominent in Malaysia waters, contributing to the nation's gross domestic product (GDP) and providing sustenance and protein. Among these activities are the landings of different fisheries resources from different landing districts, collated on states level, and officially reported annually. However, contributions of these landings to GDP are not adequately reported; moreover, fuzzy terms used in some cases were not evenly represented. Therefore, in the context of marine geospatial data infrastructure (MGDI) decisions, these constitute fuzzy decision problems resulting from stakeholders' subjectivity and uncertainties. In this paper therefore, evaluations of reported landings from 2006-2010 for western coast of Malaysia were investigated using fuzzy inference system. Categorisation of these contributions to GDP appropriately analysed to assist stakeholders in making informed decisions. Additionally, this novel approach is yet to be reported in literature to cases of fisheries landings and GDP across Asia and beyond.
