The paper embodies to determine the sequential pattern of feeding behaviour of chocolate mahseer in pond condition. The diet composition of different developmental stages of Neolissochilus hexagonolepis during fry, fingerling and juvenile were determined based on the analysis of 98 specimens (17 fries, 43 fingerlings and 38 juveniles), collected from the pond environment of Mahseer Hatchery Complex of ICAR- DCFR, Bhimtal. Zooplanktons were the most dominant prey category (%F = 129.38, %N = 45.73) in fry, while phytoplankton's were the most dominant prey items in fingerling (%F = 139.59, %N = 63.67) and juvenile (%F = 233.88, %N = 70.84). The results of the study revealed that fry and juvenile seems to have a higher feeding activity in relation to fingerling and the diet of the fish varies with different stages of development. Hence, the fry are carni-omnivore while fingerlings and juveniles are herbi - omnivore.
