Just this morning bought a couple of kilo of hemp from a local farm feed supplier... it is under new ownership, and the lass said that she had sold a few sacks of the stuff to anglers in the last two weeks, so using hemp is still, or seems to be a staple of the coarse anglers armoury.
Last year I gave hemp a miss entireley and concentrated on feeding micro halibut pellets in place of hemp, well looking at results in my diary, it seems that Hemp attracted a larger number of smaller fish, feeding pellets made a difference in that larger fish seemed to more in evidence , whilst sub 8 pounders were mostly absent .
I know its not scientific in any way, as my best double some years ago was taken using an open feeder filled with hemp and blocked with ground pellet and bread groundbait.... contrary to the above.
Anyway, this year I am going back to using hemp, I am thinking about hair rigging a few seeds again as a hookbait, as when I have done this before I have had unexpectedly large roach from the middle of the barbel swim, they dont put much of a bend in my barbel rods, but are always welcome.
