One further point of interest dumbo. I did not always live in Germany,
and for quite a while when I lived in England, I worked part time as
a fishery officer for the Northumbrian Water Authority.Which is now
simply known as "Northumbrian Water". As I have also done for several
water authorities here. In case you are also too stupid to Google
that, ( surprising really, as somebody recently intimated that anybody
asking questions on Usenet should automatically have enough "net
savvy" to use Google), here is the link;

http://www.nwl.co.uk/Reservoirsenv.aspx

I am sure they would even provide you with information as to the
rearing and stocking techniques and policies used on their large
collection of waters, if you remembered your manners long enough to
ask nicely.Maybe this information is even on their site? Of course,
you would have to look and see.

However this may be, you really are a most tiresome idiot, and I can´t
be bothered with you any more.
