Fishing for migratory fish (Salmon and Sea
Trout) is not allowed on Sundays. Originally
this law was applied to netting stations.
Also called a "slap" it enabled
at least some fish to get past the nets and
up the river. These days virtually all the
nets have gone so it applies only to rod anglers,
but the principal is the same. It gives the
fish (and people that work on the river) a
day off! The other reason the law was originally
brought in was religion. The Church feared
that congregations would fall if fishing was
allowed on Sundays.
It is perfectly legal to fish for other species
(brown trout, coarse fish, sea fish etc,)
on Sundays. A few beats close all together
on Sundays so be a little careful.. Check
the venue rules before you turn up!
