What it is
Trotting is the river skill, not a single float. A stick on a gentle crease, an Avon on a heavier glide, a bolo when you need to hold. You feed a line, mend the bow, hold back to lift the bait, and let it run to search.
It is older than the method feeder and still the most satisfying way to catch roach, dace, chub and the odd barbel on running water. Depth, pace and feeding are the whole game. Five bad trots while you find them are normal; then you stay on that line.
Rivers, streams and drains in England and Wales are closed to coarse fishing from 15 March to 15 June inclusive. 16 June is opening day.
