This thread has finally enabled me to identify a fish I caught back in 2007! I visited a local water and caught a fish that thwarted me in the id stakes. It looked like a hybrid but like no other. About the same time I was also having problems with some of the F1s/goldfish from the same water. They turned out to be gibel carp which meant a consignment of fish from abroad. That was the clue that my mystery hybrid might be an incomer and some careful checking has revealed that I caught a 'vimba' that day.
The golden rudd shown above is just that, a rudd. As for chub x bream, that combination doesn't seem to work (Colin Pitt thesis) so might have been something else??????????

Mark, it was swimming with a shoal of chub. It looked chubby but very breamy as well. I cannot remember where I looked it up but at the time I read somewhere that the hybridisation was very rare but possible. I have always believed that is what it was. I shall try to find a reference again.
Edited, Mark I found a reference by you on this subject in this forum FM on 12 th August 2011. You said it was possible but never seen one outside a lab. I am convinced due to its size that this may have been a million to one chance. I dont think there are ide in this river. The fish was just too deep not to be some sort of bream hybrid.
Edited again. There were a lot of silver bream in the Ancholme at that time. I never considered a chub x silver bream hybrid due to its large size and silver bream being so small, but who knows.
