Hi Andy and welcome to Maggotdrowning.
The fish in your picture above is one of the many types of Hybride Carp it may be a cross with any of the following Brown Goldfish, Cruican, Goldfish.
Or i could be what is called a F1 hybride which is a mixed cross that a lot of waters now stock as they only grow to about 4/5lb but grow quick.
Also the fish in the picture below (from your site)(hope you dont mind) is a small Carp and not a Bream as you quote.
Some nice fish pictured there from your trip.
Hope the above helps.
