This dissertation examines the fish availability and marketing system of a fish market in Deoghar, Jharkhand. It finds that the dominant fish species available are rohu and katla, comprising 70% of the market. Fish come from local ponds, rivers, and farms in Deoghar as well as imports from Bengal and Andhra Pradesh. The most common marketing channel involves fish farmers and fishermen selling directly to retailers and then to consumers. While the fish market plays an important role, it faces constraints like lack of cold storage and proper handling techniques. The study recommends modernizing facilities and training workers to improve the sustainability of the local fish market.
