<div style="text-align: justify;">Fish samples of Indian hill trout Barilius bendelisis, were collected from the Gaula river (290 17&rsquo; 25&rsquo;&rsquo; N Latitude, 790 32&rsquo; 143&rsquo;&rsquo; E) and reared in captive condition at Directorate of Coldwater Fisheries Research, Bhimtal (29021&acute; N, 79034&acute; E, altitude 1370 m MSL).Gonadosomatic index was found maximum in May for females (13.24 &plusmn; 0.92) and males (1.13 &plusmn; 0.07) respectively indicating a single spawning period of this species under captivity. Absolute fecundity (total number of eggs) varied from 320 to 4000. The average absolute fecundity was 1661 &plusmn; 304.6 at a total length 10.07 &plusmn; 0.30 cm and body weight of 11.92 &plusmn; 1.23 g. Histological study of the ovary &nbsp;revealed the presence of oocytes at different stages of maturity with a maximum number of the mature oocytes during April to May. &nbsp;Results of the present investigation suggest that B. bendelisis belongs to a category of low fecund fish and spawns during April and May under captive condition.&nbsp;</div>

<div style="text-align: justify;">The study describes, for the first time, captive breeding, embryonic and larval development of Barilius bendelisis. The captive breeding trial was carried out in April, in fish farm of Directorate of Coldwater Fisheries Research (DCFR), Bhimtal, India using differnet doses of &nbsp;ovatide. The most appropriate dose of ovatide was reported to be 0.3 ml/kg body weight to males and 0.6 ml/kg body weight to females. Fertilized eggs measuring 1.4-1.7 mm were spherical, demersal, and transparent with dark yellow coloured yolk. Hatching occurred 140 -160 hours after fertilization at 19.09&deg;C &plusmn; 0.395. &nbsp;Newly hatched larvae were transparent with yellowish yolk reserve, measuring 5.57 - 6.71 mm in total length and characterized by pigmented eye and yolk sac which completely absorbed in 72 hours.&nbsp;</div>
