Hi smellyloo,
I agree with the live bait bit, and I don't do it. The lures that I have have barbless hooks, or if they are barbed I nip them down with pliers to make them barbless, I must admit though, the reason for this is that it makes them easier to remove from my fingers, palms, clothing and any other body/material part that they tend to stab into.
I would rather float fish for roach, bream etc, and be kept busy rather than set a bite alarm, rest my rod on it and wait.
I won't mind if a big one takes my bait, but I fish for pleasure, and am not the specimen hunter type.
As to taking fish away from the area they are caught, I think this is wrong, and how long will a live bait be alive.
