    • Abstract


      The fish matured only after attaining an average length of 700 to 770 mm. The period between July to September was established to be its spawning season. Observations on the Gonado-Somatic Index (GSI) and relative condition factor confirmed this observation. The variation in the sex-ratio during the spawning season was considered to be a remarkable adaptation towards low fecundity. The paper also comments on the problems of the Garhwal Himalayan mahseer and precautionary methods awaiting implementation in this region.
