What is the European food fish with a rounded body covered large scales?

You are likely describing a bream. There are many species of bream found in European waters, but they all share these characteristics:

* Rounded body: Their bodies are deep and laterally compressed, giving them a rounded appearance.

* Large scales: Bream have relatively large, easily visible scales.

Some common European bream species include:

* Common bream (Abramis brama): This is one of the most widespread bream species in Europe.

* Silver bream (Blicca bjoerkna): This species is smaller than the common bream and has a more silvery appearance.

* Golden bream (Abramis ballerus): Also known as the "roach," this bream has a golden hue and is commonly found in rivers and lakes.

If you can provide more details about the fish (e.g., size, color, location), I might be able to narrow it down further.
