I never myself eat any mahseer, or other Indian river fish, anything like it.
Just where it emerges from under the barrier it forms a pool which is crowded with mahseer of all sizes.
In India at least one member of the family, the mahseer, takes rank with the salmon as a "big game" fish.
He dined with me at Rijaori, and highly approved the mahseer, which he pronounced equal to salmon, but far inferior in my opinion.
I rather think the Taiping water is too discoloured and sandy for Mahseer.
