Sustainable Management Practices for Fish Waste in Madanpur and Simurali Fish Markets

Abstract

Fish is a vital source of protein in India, and the Indian fishing industry plays a pivotal role in the nation’s economy. India ranks as the world’s second-largest fish producer, yielding approximately 4.3 million metric tons of fish annually. To meet this high demand, fish production continues to rise, resulting in a significant amount of fish waste. In India, nearly 2 million metric tons of fish waste are generated annually, with West Bengal contributing a substantial 1,770.310 tons in 2019. Our research concentrates on the Madanpur and Simurali fish markets in the Nadia district. These markets generate substantial quantities of fish waste, often mismanaged due to the lack of awareness among fishermen. Various forms of waste, including fish scales, swim bladders, and fins, are prevalent. Our survey report underscores the need for proper management of these waste materials to ensure sustainable growth and mitigate the environmental pollution resulting from fish waste. Fish scales, in particular, serve as a valuable source of chitin and collagen, finding applications in cosmetics, pharmaceuticals, and the food industry. Additionally, fish waste can be processed into fish food, offering a balanced diet for Thai Magur and ornamental fishes. In today’s context, it is imperative to educate stakeholders about fish waste management and raise awareness about the adverse environmental impact of neglecting this critical issue. By addressing these challenges, we can harness the full potential of the Indian fishing industry while promoting environmental sustainability.
