Heteropneustes fossilis commonly known as Singhi, occurs in freshwater bodies like pools, tanks, lakes, stream and rivers of india. Its is an air-breathing fish containing pharyngeal lungs as accessory respiratory organs which enables it to tolerate low oxygenated and eutrophicated water bodies like Sarua lake Campiorganj, Gorakhpur, U.P.. There is no detailed study was made on morphometric biology of Heteropneustes fossilis directly from particular water body. In the present study revealed morphometric characterstics of H. fossilis by using multi-linear dimensions from Sarua lake Campiorganj, Gorakhpur, U.P. India. A total 42 individuals of Heteropneustes fossilis were collected with the help of local fisherman by using different type of nets between September 2023 to March 2024. For each individual, total numbers of fin rays were counted with the help of magnifying glass. The body weigh were measured by using digital balance and various lengths were taken by using slide calipers to the nearest 0.01 gm and 0.01 cm accuracy respectively. The body weigh were ranged between 7.5 to 86.7 gm, and total length ranged from 109.0 To 130.1 mm. The fin formula of Heteropneustes fossilis is: dorsal, D.6-7; pectoral, Pc,1/7; pelvic, Pv. 6-7; anal, A.64-65; and caudal, C. 14-17. The findings of the current study can be very effective for identification and stock management of this particular species in the Sarua lake, Campiorganj, Gorakhpur, U.P., India.
