The objective of the present investigation aimed to determine the sexual maturity of a commercially important ornamental foothill fish Barilius barna from the Tamsa stream of Doon Valley, Uttarakhand, India. To comprehend its maturation biology, the study was carried out for a period of one year by applying the Dobriyal index and Gonado-somatic index. The values of D.I. and G.S.I. for both the sexes were observed maximum in the month of May and June respectively and minimum in August, indicating its absolute spawning period during the month of June to August.Abstract
