The Crucian Carp (carrasius carrasius) is an elusive member of the Cypranid family which is very closely related to the Common Carp of British waters. The Crucian Carp is a small member of the Carp family, which rarely exceeds a weight of 1.5kg.
The British rod caught record for Crucian Carp is 4 lb 9 oz 9 drm, caught by Martin Bowler in a lake in southern England in 2003. There have been various bids for a breakage of this record since, but they have been passed off as the specimens have not been said to have been "True" crucians.
