From Waste to Wealth: Zero-Waste Catfish Processing as a Strategy for Food Security and Environmental Sustainability

Food security refers to a condition where sufficient food is available to meet the community’s nutritional needs in both quantity and quality, distributed equitably, and affordable for all. Catfish (Clarias gariepinus) is highly popular among Indonesians due to its good quality and economic value, making it a vital food source with easily accessible raw materials. Previous studies have explored the nutritional content and characteristics of various catfish parts to promote product diversification that provides social, economic, and environmental benefits. Recently, the local community of Kutu Wetan, Ponorogo, developed methods to enhance food value by processing catfish into fish sticks, nuggets, crackers, and shredded meat. These products are widely consumed by the community and play an important role in local culinary practices due to their zero-waste approach and economic contribution to the region. This paper examines the potential of catfish-based diversified products in enhancing food availability and transforming fish waste into a sustainable resource. Addressing the challenges of catfish waste management is essential for promoting food security and advancing environmental sustainability across regions.
