Desi Singhi, also known as native catfish (Heteropneustes fossilis), is a small to medium-sized freshwater fish found in India and Southeast Asia. Known for its hardy nature, Desi Singhi thrives in various water conditions, including low-oxygen environments, due to its air-breathing ability. The fish is prized for its high protein content and medicinal properties, making it a popular choice in traditional diets. Desi Singhi grows quickly and is disease-resistant, making it an ideal species for small-scale and commercial aquaculture operations.
