Feast your eyes on the following monster of a fish - called the Golden Mahseer (Tor putitora) - regarded as the king of fresh water game fishing. My own records of this fish are: 27 KGs in Tingtibi, 23 KGs in Sheytikharey, Kalikhola, 19 KGs in Harachhu, Wangdue, 15 KGs in Burichhu, Tsirang and 13 KGs in Piping, Chhukha.
If you do manage to hook one of these beauties, I can guarantee you that the adrenaline rush would be well .... subliminal!
Mahseers are migratory fish - thus if it is still in Changchey - it can only mean that the fellow is a resident - a rarity but not uncommon. This is almost November - they should have already headed for the Bay of Bengal by now.
