Di-Morton,
If you mean takeing fish from your venue [?] [V]
you don't, they are not yours to take.
If you mean keeping them in a keepnet,
as long as you use the standard recognised type and size
and fishing rules allow you to on the venue you fish
then every thing should be ok. [^]
You appear to come across as someone who is new to Angling
if not my apologies, [:I]
I hope you have a current Rod license bad voodoo if you don't
as you will get hammered and definitely wished you had,
finaly do you have permission to fish the waters you visit,
either club member or day ticket holder,
if so then you are not as naive as you appear to make out.
Harry.
