This study was carried out to compare the nutritional values of seven freshwater, air-breathing fish species commonly found in Assam, India. The fish included Channa punctata, Channa striata, Channa gachua, Channa marulius, Heteropneustes fossilis, Anabas testudineus, and Clarias magur. Samples were collected from the Kamrup district, and their protein, fat, moisture, ash, and carbohydrate contents were analyzed. The results showed that Channa marulius had the highest protein content at 24.94%, while Clarias magur had the lowest at 14.3%. Interestingly, Clarias magur contained the most fat (8.14%), and Heteropneustes fossilis had the least (1.52%). Moisture levels were high in all species, while ash and carbohydrate contents were quite low. These findings could be helpful for researchers, nutritionists, fish farmers, and consumers in choosing fish based on their nutritional benefits and for future studies.
