Rainbow Trout culture and seed production at Arunachal Pradesh

Arunachal Pradesh has got immense scope for rainbow trout farming particularly in the district of West Kameng and Tawang. The water and temperature is favorable for its culture and propagation. However, there has been a constraint of seed availability of rainbow trout in the state although few numbers of brown trout eyed ova was produced at Shergaon and Nuranang trout farm.

Keeping this in view, ICAR-Directorate of Cold Water Fisheries Research, Bhimtal made an effort to transport a consignment of rainbow trout from Jammu & Kashmir during the year 2009 and reared them in the raceways at Shergaon Govt. trout farm. The eyed ova developed into brooders during 2014-15 in the farm condition under technical support of ICAR- DCFR.

However, it was realized 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 Department of Fisheries, Govt. of Arunachal Pradesh, 1 Lakh fry of trout has been produced during 2014-15 at Shergaon Govt. trout farm, Arunachal Pradesh for the first time.

ICAR-DCFR has taken further initiative 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 has been maintained in the farm creating further avenues of trout fry and fingerlings for the farmers of the region.
