Having spooned a couple of fish and found them full of shrimp (some still alive and swimming around in the sample jar!), on went a dead-ringer and attempts to work it as imitatively as possible.
Not a touch
(Why would a trout want to go after an imitation with thousands of the real things swimming about on the bottom? Even if it thought the imitation was real, why select that one with so many others around, a bit like the 'chance' on the lottery?)
Back to the cats-whisker and catching trout
Sometimes something different for lunch is a welcome change.
