canals can now be fished year round,with a few exceptions,such as the glastonbury canal in somerset (aka the south drain).
I believe that this water is subject to a close season because it runs through an area designated as a sssi,esa,nature reserve etc.
personally,i`d like to see the close season imposed on all waters again,these idiots who flout the rules and fish rivers in the close season,would then have no excuse,plus the fish would get a rest.
