Abstract: The present study primarily concentrates on the waste generated by the fisheries sector and its effect on the human health and environment. Fish wastages attract pathogens, create bad odor, general aesthetic degradation, contamination of water resources and other hazards. Therefore decision makers move for some alternative methods of disposing commercial fish wastages. Fuzzy mathematical modeling plays an important role in decision making techniques. In this paper we use fuzzy multi criteria group decision making method VIKOR to help the municipal authorities to choose the right alternative method for the safe disposal of commercial fish waste.
