The success of any aquaculture project or fish farm depends to a large extent on selection of a suitable site. Site selection using the conventional method, based on very limited data, can result in inaccurate information and cause discrepancies among the implementing agencies. The utilisation of remote sensing and geographic information systems can provide a useful source of additional information. This article provides a GIS-based analysis of the suitability of sites for trout farming and the establishment of sport fisheries in the Menchukha valley, Arunachal Pradesh.
At an altitude of over 3,000 metres, Shi Yomi District is characterised by numerous perennial river drainages dissecting the mountainous terrain into deep gorges and narrow valleys.
The most sought after trout species for aquaculture avenues is rainbow trout, whereas the brown trout is preferred for sport fishing in natural water bodies. The Yargyapchu River is a hub for angling as this drainage contains many snow-fed streams harbouring trout. However, trout aquaculture is still in its infant stage in the Menchukha valley and much more effort has to be carried forward to expand trout farming in this beautiful region. Seeing the potential of trout farming and angling, initiatives have been taken by the Department of Fisheries (DoF), Government of Arunachal Pradesh, in establishing trout hatcheries and a couple of trout farms in different districts of the state.
