Abstract: Freshwater fishing is a major source of income and protein for the riverine populations of most tropical and subtropical regions. During present investigation a total of 1006 specimens of Sperata aor and 966 specimens of S. seenghala were collected from the middle stretch of the Ganga river at Prayagraj, Uttar Pradesh. Size range of fishes varied from 12.2 to 136.4 cm and 11.8 to 129.7 cm for S. aor and S. seenghala, respectively in during the months from September 2015 to August 2017. The 80.1-90.0 cm size group fishes of S. aor was shared (16.10%) while 70.1 to 80.0 cm size group of S. seenghala was shared (19.77%) in exploited stock. Middle size group was maximum exploited compared to lower and higher size group of both species. The exploitation pattern was not systematic for heavy recruitment. The result also indicated that the fishing activities should be prohibited during the breeding season of these fishes.
