Things certainly change over time. Going back a couple of centuries there used to be ‘Gudgeon parties’ held on the banks of the river Thames, where the Ladies and gentlemen used to catch gudgeon; and fry them up and eat them just like white-fry. NB: it must have been a bit upstream of London though as the Thames was full of excrement back in those days
And also Pike were regarded as being much better for the table than Salmon. Plus Lamprey were considered good to eat.
I have a book ‘the fisherman book in pictures’ which has pictures taken from somewhere on the continent showing them netting Carp and Pike with a large Siene net for selling for the table, and using several lakes for a type of crop rotation.
I have eaten Carp and Pike and jellied eel with liquor in the past but didn’t enjoy any of them, my favourite fish to eat are Cod, Haddock and Skate; preferably coated in breadcrumb or batter, together with chips, mushy peas and a Gherkin, plus various Crabs, Prawns and lobsters.
