In the last week I've seen two occurences at my local fishery which I'd never seen before....and am unlikely to see again.
1) Whilst stalking fish I saw a rainbow of about 2lb heading along the margins at very high speed. When it was opposite me it veered sharply towards the bank and, given the speed it was moving, came right out of the water and ended up near my feet, about six feet up the bank. I got it back into the water and it swam off.
Given the maximum size fish in the water is 6/7lb I can't imagine it was being predated but perhaps someone can explain.
2) Again whilst stalking I came across a fish of similar size sitting stationary in the water about 6" down with it's nose pressed hard against the bank. It could certainly see me but it didn't move.
I waved my arms over it.....nothing!
I put my hands in the water next to it.......nothing!
I eventually took hold of it.......nothing!
Then I turned it round facing away from the shore......and it swam off!

Any info on these events, particularly the latter, would be welcome.
