OK I can tick carp off my list. I asked the owner of the campsite about it. He went over to one of the locals table, nicked some of theirs and gave it to me! :-)
Very tasty, but boney.
Apparently they send the trout from here to queen Elizabeth. It takes 7 years to grow to 1kg.
I'll try it tomorrow.
Oh and they then donated some baluska. Again really tasty.
So we've drunk and stuffed our faces all night.
Bought a round for the locals who donated their carp and belushka. The bill? 29Euro :-)
