Wildies is the name given to the original carp which had become established in British waters and it is argued became endemic inside our shores (not indiginous), Walton is quoted thus
" The Fourth Day, Hops and Turkies, carps and beer, Came to England in a single year"
I think however old Izaak, may not have notice the wildies which the Romans introduced prior to the arrival of the North American Turkey? Wildie were the fish which my ancestors used to breed for the Monestry Table.
The King Carp, although the same specie (Cyprinus Carpio), are however a genetically modified version, bred specifically for the table, the ideology being to produce a fat fish which you didnt have to descale (the Leather variety) throw backs of this process are your mirrors, leathers, line mirrors and the rest of the fat domestic pigs which we now have floating around in our lakes and pits. Because the King strain are of the same genetic base type as the Wildie, once King Carp had been introduced into a water containing Endemic Wildies, the gene pool (it is likely) would become polluted and thus the varieties mixed, other throw backs include Ghost carp, koi and fully scaled Mirrors. According to old Charlie Darwen all varieties will either speciate (decided by man) or revert back to their original format, this being over an evolutionary time scale.
My best King Common is a 39lb French Fish and my best English Wildie was 8lb, the latter fought in a comparable manner to the Amercian St Laurence fish, while my French fish was just kinda reeled in.
The Crucian Carp is an excellent fish, were the F**K have they all gone Ron?
