European freshwater fishes ID

Alpenzoo Innsbruck. Species signed: Barbus barbus, Chondrostoma nasus, Rutilus virgo, Rutilus rutilus, Cyprinus carpio, Vimba vimba, Scardinius erythrophthalmus, Alburnoides bipunctatus, Abramis brama, Leuscius idus, Rutilis meidingeri

I know number 3 is the common barbel, Barbus barbus
Pretty sure number 2 is the bleak Abramis brama

Unsure about 1 and 4

2 is definitely a Common bream, and 3 is definitely Common barbel, so you've got those two correct.

1 might be a European chub (Squalius cephalus) but I'm not entirely certain. Could also be an Orfe (Leuciscus idus).

Number 4 is very difficult, as this resembles a Rudd, but there are multiple similar species (Rudd (Scardinius erythrophthalmus), Roach (Rutilus rutilus), Danube roach (Rutilus virgo), etc)

@Mr Gharial. European chub is defenitely possible, in which case that species is not signed.
