Abstract
The paper deals with maturation biology and spawning behaviour of a hillstream fish Botia dayi (Hora) collected from river Khoh in the foothills of Garhwal Himalaya, Uttaranchal. Seven maturity stages were determined for the fish. Based on GSI, Dobriyal index and availability of different maturity stages during months, it was inferred that the fish spawns during August- September as one time protracted spawner.
