Its so hard not too put too much pressure on trout / salmon or to avoid rubbing off their protective slime, glove or not. I was so upset with my seeming inability to release a trout / salmon unharmed that I've learned to stop handling them altogether. They are so fragile compared to bass...Instead, I bought a pistol-grip type hook removal tool and I hold the fish up by the line and grab the base of the treble hook on my Mooselook or Top Gun. A flick of the wrist is usually enough to drop the fish right back in water, no handling. I do this exclusively with trout / salmon now and the fish zip away, as opposed to swimming slowly (or floating or doing the i'm-going-to-die-in-five-minutes roll). I think this is a better way to release trout/salmon unharmed than any means of handling the fish. I learned this from a guide up on Moosehead in ME. As soon as I started doing this my release of fish (unharmed) improved dramatically.
