The water and temperatures there are favourable for its culture and propagation. However, there has been a constraint of seed availability of rainbow trout in the state, as only relatively few brown trout eyed ova were produced at Shergaon and Nuranang trout farm.
Keeping this in view, ICAR-Directorate of Cold Water Fisheries Research (DCFR), Bhimtal made an effort to transport a consignment of rainbow trout from Jammu & Kashmir state during the year 2009 and reared them in the raceways at Shergaon Government trout farm. The eyed ova developed into brooders during 2014-15 in the farm condition under the technical support of ICAR- DCFR.
However, it was realised that seed production could be possible through the developed brooders at the farm.
Therefore, ICAR-DCFR supported technically and financially to install a ova house having hatching facility in the said trout farm in order to solve the problem of not getting fry and fingerling of trout.
It is noteworthy to mention here that with all these efforts of DCFR with the Department of Fisheries at the government of Arunachal Pradesh, 100,000 fry of trout has been produced during 2014-15 at Shergaon trout farm for the first time.
ICAR-DCFR has taken further initiatives to improve the seed production potential of trout providing balanced diet and other management techniques.
At present 500 kg of brooders of both rainbow trout and brown trout have been maintained in the farm, creating further avenues of trout fry and fingerlings for the farmers of the region.
