THE CONCEPTUAL DESIGN OF DECISION SUPPORT SYSTEM TO PRESERVE NEOLISSOCHILUS HEXAGONOLEPIS (MCCLELLAND, 1839) IN PELUS RIVER, PERAKNUR SYAFIQAH CHE HUSSIN, LATIFAH ABD MANAF AND NOR ROHAIZAH JAMILAbstract Over the past three decades, Malaysia extensively exploits the natural water resources to satisfy increasing demands of human and industrial development in line with the rapid urbanization. This exploitation contributed to the degrading of water storage and decreasing in water quality which consequently, fluctuates the habitatÂ’s quantity and quality of the river ecosystem. The biological functions of the fish population are highly dependent upon the characteristics of their aquatic habitat. Thus, any alteration to the river ecosystem will put the integrity at risk. To determine the condition and action for fish habitat is time-consuming. Therefore, advanced technology tools such as Decision Support System (DSS) is needed in making decision process. This system has been developed to support the user by applying the easy-to-use concept and comprehensive one for preserve the target species that focus on habitat condition, which includes physical and chemical factors. The concept applied in DSS for this study is based on IFTHEN rules concept. The Neolissochilus hexagonolepis (McClelland, 1839) in Pelus River, Perak fulfill all must have criteria as a target species. The objective of this paper is focusing on the brief description of aims and concepts in developing Decision Support System in order to preserve the target species, Neolissochilus hexagonolepis (McClelland, 1839) in Pelus River, Perak.
